SS-84  - Thank you Jim. I spent two hours last night discovering what I have been missing from my CDs. I finally found the amp that would match my DIY full-range speakers and at a price that did not leave a hole in my pocket. Thank you for the passion and effort that have been placed into the building of this amp.  It shows in the results. I would like you to know also that this is my favorite amp for music - it's like being rocked to sleep. It is connected to a stereo speaker that I made with Audio Nirvana full-range 12 inch speakers.  They match better than a husband and wife.  Basil C. (California)

SS-4772 - Dear frenzeltubeamps, Thank you very much!!! I received it today, it's amazing!!! Sounds great!!! Will recommend you to my friends.  Klepatskayavi (Russia) 

SS-4772 - Hey, thanks for making such a great amp and excellent customer service. Jeb. B (North Carolina)  

SS-4772 - Jim,  Christmas in May!  I received the amp last Friday and unpacked it Saturday.  It is absolutely the most beautiful piece of stereo equipment that I have ever seen...   Robert O. (Texas) 

SS-4772 - I just want to say " WOW WOW WOW" After a few days of listening to records on this amplifier, the sound coming out of my pioneer HPM"S is so smooth and warm.
The customer service is in the highest standards. They kept me informed durring the build of the amp. Thank you. Willy S. (Colorado) 

SS-4772/KT88 Jim, I purchased my tube stereo about 5 years ago.  I have wanted to give a review but since it was so hot in Hawaii, I decided to save my beautiful Tube Amp for later. I finally moved to Oregon and unpacked my Kt-88 Tube Stereo Amplifier with rectifier tube. I run it through a pair of Concept CE-1 speakers.  I listen to 80's hard rock  Ozzy and new bands like Halestorm. I was listening and checking out the amp and then i saw the presence pull for edge. This made the vocalist like they were standing right in front of me singing, I was blown away with the incredible live like sound. I was using a vintage ipod 80 gig with charging input not the headphone output, which does not sound as good as using the charging style  to rca. The sound is big and I hear so much more and feel the bass. Before making my decision on purchasing an amp. I looked at quite a few Tube amplifiers. Most offered not much of anything in the way on control features and all the small amps  were on circuit boards and had mixed reviews. The amps offered by other companies were small and started around a grand on up and were on a circuit board. I also was looking for used Tube Stereos. I came to the conclusion I didn't have time nor want to repair my new or used tube stereo. I made my decision and purchased a Frenzel Tube Stereo with KT-88 tubes. If you looked at other Manufacturers amps with Jims options you would pay about 2 Thousand on up. Jim offers an incredible product all hand wired(no circuit boards).  If your looking for a tube Stereo, look no further. Jim makes an incredible amp for the money. He ships his amps in a 2 boxes with about 4" of foam style blocks all the way around the product and the product is in its own box. Thats 2 boxes and I received my product in Hawaii in prefect condition. Jim does an A++ job on all his amplifiers and packing. Jim, Thank you for the Awesome Stereo.  Kirk Greenman  (Oregon)

SS-4772 - Hi Folks at Frenzel I wanted to wait till I let the SS-4772 Stereo Tube Amp get a good burn in on the tubes. So unboxing and hooking up the cables I was impressed Ok right out of the box, let the tubes warm and let the DAC send it signal from my laptop for some tunes it was close to what I wanted out of my stereo tube amp. A few tweaks with the settings and boy I don't need to let the tubes burn in, love it. It takes every kind of music played on it!!!, Thanks, Folks! The depth of the music is what I was looking for!  Richard Griesser  (Texas)

FM-5E3SD - I have two Frenzel Tube Amps.. One is a 25 watt 2008 Retro FM-5E3 Deluxe Plus and and the other a 40 watts 2011 FM-5E3 SD Super Deluxe. Jim Frenzel makes the real deal....and at fair prices that all can afford.. I used the 25 watt in the studio exclusively to record our "Devil on a Dirt Road CD." You can hear how I used my Frenzel at www.jackrobertsharveyband.com. All the CD songs are there and free to listen to. I couldn't be happier!!! Thanks Jim! — Jim Roberts & The Jack Roberts Harvey Band (California).

FM-5E3SDR - Hi Jim!! How are you? Just writing to say that I've received the amp today, and I must say it Kills!! Really really sweet, warm, I love both inputs and the reverb also sounds great!! Really, Im very impressed! Its so much better than my expectations :) Thank you so much for the attention and fast shipping. Thank you very much! Regards!! Julia Brandao. (Brazil)

FM-5E3SDR - Hey Jim, The amp is just too damn great to keep to myself, so my badass pal Steve has been exercising it .... One of the best blues players in Virginia Beach is now on my wait list to play it :-) Thx Pal and hope all is well in Texas!!! Donny P. (Virginia) 

FM-5E3SDR -  Jim, So, let me just start off by saying about the amp..."I HAVE NEVER PLAYED AN AMP SO UTTERLY PERFECT IN EVERY WAY! THANK YOU, THANK YOU JIM!!!! I mean, really...with the push pull Presence and the Bright and Normal channel, it's literally like being able to play 4 distinctly different amps, all of which sound incredible! Really Jim, what you made for me is hands down, not only the BEST amp I have ever owned, it is the best amp I could literally ever imagine owning and if I have anything to do with it, that amp will stay with me till the day I pass away.  This amp is a TRUE piece of art and it will ALWAYS be treated as so!!  You truly made EVERYTHING I could have ask for in an amp and EXCEEDED what I had even hoped for. Danny Drake (California)   

FM-5E3SD - Hi Jim, I made a combo cab (see Pictures page) for my Frenzel Super Deluxe head......I’m pleased with the results and the amp sounds great!! Lots of compliments on how good it sounds (and a few compliments on how good it looks...lol). I borrowed some design ideas from here and there and added some of my own as well. The speaker and amp are separated from each other by 3/4” plywood and there are deflectors that direct the sound coming off the back of the speaker out the side ports.  Glenn T.. (British Columbia, Canada) 

FM5E3SDX550 - Jim, 6 hrs in. Living room Fender 1/4 power is the most exciting so far with the 410. I was worried I’d not get a great 5E3 with the 6L6s but am very much not disappointed with each cab I’m trying. Loud cleans and 2 Marshall preamps are working with most cabs and Strat also. Tele loves this amp. Thank you, thank you, thank you. Andy S. (Illinois)​

​

FM-5E3SD - I want to thank Mike Gee Kustoms for the amazing "Rivers Cuomo Strat-o-Master" Guitar and Frenzel Tube Amps for the amazing "Super Deluxe" all tube Guitar amp. Without affordable High quality instrumentation and Equipment like this I would not be where I am today. Dominic Antonelli  

FM-5E3SD - Hi Jim. I thought I’d send some pics of my latest cab build for my Super Deluxe. Thanks for building a GREAT amp! Glenn Taylor (Canada)  
FM-5E3SD RETRO - Hey Frenzel Team - Proud to say, as of yesterday, I now own an awesome, lightly used, FM-5E3SD  "Super Deluxe with the Quad of 6V6's and the 6SL7 Retro preamp upgrades. It sounds amazing; looking forward to rocking out with this amp for years to come... Ryan D. "RCD Media/The Scarecrow Project Band" (California)

FM-5E3SD - Custom "Dukane Mojo SD"  -  (One of our customers requested that we convert a  vintage 1950's Dukane PA he had into a Frenzel Super Deluxe with lots of Mojo! Here is his review.) "Hi Jim, Got the amp. Nice work! Thanks for the bag-o-parts, too :) So far, I'm diggin' the Marshall side - seems brighter and quite "Plexi"-like. I'm running the gain full tilt on the pre, not getting much breakup, but just enough to put just a whisper of hair around the edges. This thing gets incredibly loud in a heartbeat - hardly moving the Master. I like it with the "Edge" control pulled (really opens it up a lot - the response comes alive), but it gets a lot louder.  I found  out quickly that I have to be very careful. I play Tele's, so I know humbuckers would kick it more - just not very much of a humbucker guy. I hooked up my Radial Elevator Boost pedal - and OMG did the amp COME ALIVE!! Now I don't have to crank it...it's awesome!  Long story short, there's still NOTHING like a great tube amp. And, now I have another GREAT tube amp - thanks to YOU! - and, it's ability to work with the Radial pedal is spectacular! So...I'm thinking that your 'DuKane Mojo SD' will also take eagerly to my pedal board (when I get a chance)". Ross J. (Minnesota)

FM-5E3SD - Hi Jim. Sorry it's taken me so long to let you know what I think of my amp. I received it last Tuesday and I wanted to do an unboxing video for YouTube at my friends studio. Well life happens and we weren't able to do it till Sunday. WOW! It's everything I had hoped for, and more.... My friend and I played and played. Thank you for putting out a solid product. I'm sure we will be doing business together again in the future. Bob P.  (Oregon)  

FM-800Z - Dear Friends at Frenzel...Thank you for this wonderful little FRENZEL FM-800Z amp / preamp. I am fully utilizing its capabilities as both amp and preamp and also combining the F and M channels to get a really nice tone. I lean a little heavier on the M channel. This amp seems to get better with time , warmer and richer.  The power amp section sounds great and gets actually pretty loud. The tone controls are very nice in that you can get an excellEnt variety of tones with them. The Rocker 800Z sounds so good with rich harmonics and overtones that a person can learn to play better and get those great tones. The level of build and sound quality would be very challenging and extremely expensive to beat. I want to thank all people at Frenzel that were involved in building this great little amp / preamp for doing such an excellant job. In the future I will probably order the 5E3-SD with a few upgrades. A local craftsman built the cabinet with solid teakwood. Sincerely, Donald K Bazille (Thailand) 

FM-800Z - Hi everyone at Frenzel Tube Amps, I just received the FM 800Z preamp.  I have been blown away by its incredible sound.I am using it with a Rickenbacker 4003 with the Ricosound.  The neck pickup goes to the fender channel and the bridge goes to the Marshall.  I put more bass on the fender channel and more treble on the marshall channel and it sounds amazing.  When you dig in it starts to growl and get a little more top end sizzle. The two channels are perfect compliments to each other.  The fender very fat and warm.  The marshall more bite in the top end. You get way more of an overdrive sound than I expected as well.  That's if you want it.  I will be using this for recording and most likely live after I build a nice case for it. Thank you so much for such a beautiful well thought out amp. Your newest fan,  Chris G. (New York)  

FM-800Z - Dear Jim, A miracle has come to pass - it arrived safely two days ago! I had very little time so far, but my initial impression is - awesome! It was really worth it. Both channels sound great. The bright switch and bass enhancement make it even more versatile. My setup is your preamp into a 35 watts tube poweramp from a local builder into either one or two 12'' cabs. I have a ABY switch on my pedalboard and connect it with four cables so that I have time based and Modulation effects between preamp and master. There are two boosters on the board - a midboost for solo tones and a fat boost for heavy rhythm. Works beautifully! The crunch channel on the amp sounds so fat and full, way better than any pedal i ever had. It also cleans up really nicely with the guitar volume. The clean is awesome too. Quite jazzy on 'normal' and sparkly on bright. It strikes me how quiet the preamp is. Very little noise. Well done! I am looking forward to spend much more time with it. You are a real gentlemen! All the best, Frank N. (Germany)

FM-800Z - I have one of these. I run it through my Mesa Mark V 25 and it sounds fantastic. It bridges the gap between the channel 1 crunch mode and the channel 2 MkIIc+ perfectly - William B. (Texas)

FM-880Z/2U  - When my FM-800Z2U got delivered it was enclosed in two boxes, one inside the other. The outer box had two florescent green “fragile electronic equipment” stickers on it for added safety.  I was impressed when I discovered the rack chassis was made of aluminum as I don't like rust. Some people say aluminum breaks down also, I say check out my aluminum boat, it looks new after years of use and a couple of trips each year to the cost in salt water. If it were made of steel it would be a a pile of dust right now. If you live in the southern states the humidity would take out a steel chassis after a few years unless you had a dehumidifier running all the time, then it would take a little longer. I took off the bottom panel of my preamp to find that the circuit board and related electronics are mounted on the top inside panel of the preamp, how thoughtful as what little dust makes in through the cooling holes will land on the bottom inside panel where it won't affect the electronics and can be removed in one swipe of a cloth. The eyelet board is almost one quarter of an inch thick, it will never bend, stress or crack unless you are trying to purposefully destroy it. All the components are mounted point to point. The board is there to stabilize and logically arrange the components. In traditional point to point type construction the components are soldered together with no added supported, other than another component, if there were ever a need for a component to be removed the heat of the soldering process could stress the other attached components, Frenzel has removed the danger by incorporating this type of eyelet board. All the markings on the components are readily visible as there are no components mounted underneath the board where you can't see them. The ceramic tube sockets are mounted on a separate aluminum bracket which is very sturdy and will undoubtedly stand the test of time. All the components are of top notch quality and the construction is suburb. Another refreshing quality of this exceptional preamp is the simplicity of its design, there is no extra unneeded circuitry for channel switching as one only needs to use an a,b or a,b,y channel switch for full control of the FM-800Z2U's channels. When designers add circuity for internal channel switching in their preamps they always use shared components which adversely effects the quality of the sound of the preamp, they add transformer taps to run the low voltage needed for op amps as well as other solid state components which are sometimes used for channel switching or low grade effects loops (non tube type), no so in Frenzel's case, the channels are discrete meaning no shared tube stages and no shared resistors or caps, another mark of ultra high quality. It is more expensive for Frenzel to design and build using discrete techniques I don't know how they do it for the prices they charge for their products. There is exceptional care and pride oozing from every aspect of their products. I am a designer and builder of my own personal tube equipment, if I had the time to build my own tube preamp with no compromises in cost or quality I doubt it would be as exceptional, functional or attractive as my FM-800Z2U. Frenzel has made well thought out rugged products that can stand generations of being moved around and used, in my opinion their equipment will only go up in value. Speaking of functional every time I plug in to my FM-800Z2U I love it more and more. The controls are endless in sweet spots, you find more each time you experiment. The FM-800Z2U is the most “amp sounding” of any tube guitar preamp I have ever heard and I have owned them all!  The old adage “If you want it done right do it your self” does not fly in this instance as you can not do it better than Frenzel and definitely not with less cost! Thanks ever so much Frenzel! I intend to be purchasing more of your quality equipment, I would rather be playing than building. Best Regards! Gary DiCenso (Maine)

FM-DP5A3/6SL7 - Hi Frenzel Tube Amps, I received my FM-RDP5A3 Retro Deluxe Plexi 6SL7 preamp today and I love it, thanks! Issac T. (Taiwan) 

JF-5A3RDS - Hi Jim,  I had never heard a 1949 5A3 Deluxe in person, but what I noticed on internet demo's was quite how ‘fat' they sound when cranked in comparison to later Fender amps. The Frenzel Retro Deluxe does this really well, almost like a fuzz. I have only cranked the master and gain fully in its 5 watt mode, and the overdrive is different from a Blackface or Silverface style, darker, more compressed, richer. It’s versatile too. In 20 watt mode it’s loud and has enough head room, it does jazz very nicely with a hollow body, clean or slightly broken up, and it also sounds great with a Telecaster. You can do Wes Montgomery or Punk with this head. I ordered a Tremolo on mine, which is lovely and has a load of sustain. It is a dark amp, I tried it with numerous different cabs I own before I found the perfect match (for me at least), an open back 1x12 with a 70s Fane/Hiwatt ceramic speaker. It is a bright speaker so I guess that makes sense. The Retro Deluxe also works well with an old school Alnico speaker for a 50s sound. I am impressed but not surprised how nice this amp is (it’s so quiet it’s almost silent), as I have had one of Jim’s 5E3’s for many years and it is the most reliable and well used amp in my studio, wonderful cleans, nice low gain drive on the Marshall channel. This new Retro Deluxe has already received several compliments from other players who have tried mine, it is a different amp to the 5E3 in a good way.I have lots of guitar amplifiers, from famous brands, boutique makers, cheap ones and oddball ones; this Frenzel is great and will get lots of use, highly recommended. The power scaling does what it should do (3 modes), you could definitely use it as a bedroom amp if that is your need. Lastly I should mention the Frenzel service, which is always as good as it gets. I am in the UK, and yet I knew what was going on during the build via constant email updates, and it was delivered perfectly and very quickly. Super friendly people, great service, great pro amps. Thanks Jim.   Rupert Latimer (Sussex, UK)

JF-6G15 "Rack Mount Tube Reverb Unit" with Frenzel FM-5E3 "Deluxe Plus".  Hey Jim, It sounds rich...perfect...fantastic! So happy together !   I love this reverb! Getting lots of great sounds out of this "one" effect. Down right organic. Regards, Steve R. (St. Thomas, Virgin Islands)

FM-5E3SDR -Thank You very much! This is by far the best amp I have ever owned (perhaps played thru?).My Carvin guitar with DiMarzio super 2’s thru a Keeley compressor, plugged into a Mesa 2/12 cab w/Celestion V30’s gives me all the tone  I need and then some. Again, Thanks.  Brian S. (California)

FM-5A3RSD/6SL7 - Thanks Jim, Got the amp today. Picked it up at the post office, put the tubes in and used it on the gig. Sounds great! I'm really impressed with the fat, but still tight, compression of the 6SL7 tubes. Also the Lineout/powersoak/speak.sim is the best Lineout I've tested. I pulled back all the treble on the PA system and pushed the mid a bit to sound like the speaker I was on (marshall1912... which is dark in character). But then, the feel, which always is the thing that gets lost in the "line out" process, was identical to the speaker feel.   Kudos! Thomas D. (Norway) 

FM-5A3RSD/6SL7 - Everything arrived on time and in perfect shape.  Took longer to unpack the box than it did to get a killer Telecaster sound.  You guys done good...thanks!  Ken M.(Texas) 

JF-5A3RD/SURFER - Hey Frenzel Team  - I would like to thank everyone involved for the outstanding workmanship, professionalism and care you show in doing things right for the people who do business with you. The way you packed the amp so it would arrive in perfect condition is truly impressive.  I believe that of all the companies I have ever dealt with, regardless of field of expertise, your company is the one that has stood out the most. I tried the amp (JF-5A3RD/Surfer Upgrade) as soon as everything was ready to go and the sound is full and well defined. I will make sure people know about Frenzel amps among the musicians I know here in Montreal.  I'm very happy and I can't wait for my next gig.  Michel P. (Montreal, Canada) 

JF-5A3RD "Retro Deluxe" Customer Review - Thank you, Jim. My Retro Deluxe arrived today and it is an awesome harp amp. I tried out two vintage microphones with it and it sounds great! It delivers the tone I want. It’s loaded with numerous extras. It’s priced right. And it was shipped in the most secure container I have ever received,I appreciate your attention to detail in every aspect of the amp. I appreciate you sharing your commitment to outreach work as well. Frenzel embodies integrity.Thanks. May you have joyous abundance in everything you do, Best regards,Vin (Massachusetts)

JF-5A3RD - Hi Jim, I can not say enough about the quality and sound of the Sweet Little 15 and the Retro deluxe that you recently made for me. Every time I plug these in and get such inspirational tones with ease, and the value provided, WOW, Thanks, Mike H. (Victoria, BC Canada)

JF-5A3RD - Hello, I received my Retro Deluxe (JF-5A3RD) amp today. I plugged it into my Weber Minimass and then into my computer audio.  I added some of my favorite pedals to the mix.  I soon found out I don't need some of my pedals nor do I need the Minimass.  The amp sounds great and has a good range of possible tone settings with the two pull controls on the gain and bass parametric eq knobs.  Thank you for throwing in the pull deep switch on the bass control.  This amp sounds the way I hoped it would and then some.  I plan to order the Sweet Little 15 next. Dan R. (DC suburbs)

STP-50 - Dear Jim,  I just absolutely love this amp.  It has such a pure tone, even when I put a small chain in front or in the loop . I still prefer nothing in front or in the loop, but I have found, surprisingly, that I can pretty easily get into high gain territory on both channels with a boost.   Matt C..(Missouri)  

STP-100 Jim, I got my amp and it is awesome!!!  Thank you!!!  Mark H. (Utah)

FM-L5   - I received the amp and it is absolutely wonderful. PBass, acoustic with pickups, and Les Paul! Plenty of volume, various tones for each of the guitars and great as a preamp to my big tube amp. It is light and portable and going to Thailand with me soon. Quite sweet. Thank you! Axel B. (Colorado)

​

FM-5E1BF - Hi Jim, greetings from Harlem, NYC. Thanks for building my FM-5E1BF Champ Blackface with the retro 6SL7 and 6L6 options. The amp you made for me is an audio masterpiece, a unique combination of imaginative circuit design, and flawless build, using first rate parts. This is THE best amp I ever heard. I tried it out with a nice 1x12” Ted Weber AlNiCo 12A125A, rated for 30 watts, at 8Ω. I used my favorite guitar, an ‘88 Gibson Howard Roberts Fusion with a Morley M2 volume, EHX “East River Drive” and a Boss DD-3 delay. I set the amp as loud as I dared in my apartment, gain 6, (“F” voice) with the EQ flat 5s, master 7-8. I ran my guitar with both pickups on, and knobs wide open. I started with the Morley volume backed way off and got a great spanky “acoustic” sound, opening the Morley a little more and I got a sweet, round bell-ringing chime, then pushing in a little drive, and going to about half open gave me beautiful fat, wet, voluptuous blues tones, finally flooring the gas and kicking in some long delay, with the deep switch pulled gave me an authentic arena rockstar solo sound, that heavy Gibson center block felt like it could sustain forever! It’s perfect for my New York City Co-Op apartment, but it's plenty loud... one could definitely gig with it, especially as you can line it out to the FOH sound system. Thanks for your honest dealing, very fair price, and evident, master craftsmanship. There are far too few people left who do business like you do. I highly recommend your company, and I plan to bore anyone who will listen going on about how great this amp is! You should feel free to add my comments to your long list of satisfied customers. Thanks again, Augustine Nocera (New York) 

HBX-WC30 - Dear Jim, I’m back from California and could finally try the amp. The amp sounds fantastic...all the power amp options are great. The best sounds to me are both channels in parallel one dirty and one with a little bit of breakup.Thank you again for your help! I’m really glad about the amp and your excellent service. Every day I get more used to the amp. I have some expensive amps (Matchless, Chieftain, 70th Marshall with custom mod from Larry Amps) -  but your amp sounds better – period!  Stephan U. (Germany).
 
HBX-AC15  Hi Jim, I am from far east, Macau. I am a happy owner of  FRENZEL "Sweet Little 15" for more than 5 years & I really like it....by the way, a guitar technician came to fix my guitars yesterday, he said my HBX-AC15 sounds very nice & he wants to get one too. Matias L. (Macau) 

HBX-AC30 - Ok you did it again. My 3rd Frenzel- this time the Sweet Little 15/30 In a word "Stunning" The incredible clean clarity, overhead and flexibility has me stammering. I have been hunting for a few years for a mate to my vintage ES-335 and bought this one guessing/hoping it would be a match the way my other two FM-5E3 SD "Super Deluxe" amps match up to my Telecasters and I couldn't have been more right. Punchy, in your face presence, bell tone sustain,  same killer tube magic but a new voice in the stable. The 335 is out of retirement! Keep up the good work and thank you again. Leon T. (Oregon)  

HBX-AC15 - Hi there, Just received my order for an HBX-AC15. I just wanted to say how impressed I am! The build quality is incredible and the tone is off the charts! Just had a moment to plug in my Telecaster and WOW!!! Blew me away! Thank you so much for the dedication to supreme quality! Money well spent!!! Kind regards,  Gord H. (Canada)  

HBX-AC15 - Hi Jim, I can not say enough about the quality and sound of the Sweet Little 15 and the Retro deluxe that you recently made for me. Every time I plug these in and get such inspirational tones with ease, and the value provided, WOW, Thanks, Mike H. (Victoria, BC Canada)

HBX-AC15  - Hello, I just received my HBX-AC15 amp yesterday and I'm very happy with it! Brian P. (New York)

HBX-AC30 - Hi Jim & Team Frenzel - I HAVE TO SAY:  WATCH OUT VOX AC15 AND AC30 HAND-WIRED, THERE’S A NEW KID ON THE BLOCK NOW !!!   So a big thank you for this marvelous HBX-AC30 amp - like “Wwwoowwww” !!!!  A TONE MONSTER!  Genius to use that Hot Box in an amp - What a sound! and such a value!!!   Bell-like tones …i have to say I really like the bright and deep push-pulls you installed (a big thank you - wasn’t expecting them on this build!) - They seem to ’make the difference’ on my Rickenbacker 12-string tones - getting that chime and jangle in spades!  I’ve got the Boost channel set up to play live shows - and I’m getting what I need in that channel for Rickenbackers AND Les Pauls - really versatile!  And using the guitars’ knobs couldn’t be easier with this amp!  The NNFB push-pull is a game-changer for sure, love that wide-open sound, great to have the option - same with the SS/rectifier tube option…All of these switches/controls really allow for many, many tones in this amp, just gorgeous! It is everything I thought it would be and more!! My Rickenbacker 12s have been looking for these tones - and now they’re here!  Amazingly versatile for what I need to do live!  Chime, jangle, open, very musical…made for my Rics!!!!  And my Les Pauls are smiling too!!  First class all the way!  You guys are hitting ‘em outta the park!! Thanks all again for a  great amp - John Z. (Ohio)

JF-B45 SBB - Hello: I’m just emailing you again to tell you how much I love this amp.  I’ve had it a couple months now and I can’t stop playing. One week I think the Bassman side is the greatest tone in the world and the next the Bluesbreaker.  Currently I am running KT66’s in it and the tone is unbelievable.  I crank the mids and it is the bluesiest tone ever.  I put a treble boost in front of the bluesbreaker channel and I have instant “Slash” tone.  Amazing.  Thank you so much. Steve E. (Canada0

JF-B45 SBB -Jim - I love this Frenzel 50W Bass amp. Perfect tones for my Hammond and 147 Leslie and my Roland RD 300s!!! Soooo much tone over the solid state I use to use. Very warm and "meaty" sound!! I get many compliments on "that Sound"  Keyboard player.  I now can keep up with the guitars when I'm not miked! Love this amp!!! It's great clean or gritty!!  Thanks for a great products Jim!!!!  Bob T. (Massachusetts)

FM-800Z - Just wanted to say thanks for a excellent amp! I ordered this with the 1 watt amp option not expecting much from it but expecting everything from the preamp. I've owned quite a few low wattage amps have have never really liked any of them. The Frenzel's little amp option blew me away, absolutely haunting tone with all the controls set at 5 and the master cranked with the guitar's volume rolled down a bit. That was something I wasn't expecting! Ran the preamp through the loop input of a 6L6 based head that I've always thought sounded lifeless and it's like being a kid in a candy store, can't find a bad tone if I tried. Thanks again! Mark S. (Florida)

FM-5E3DP -  Hi again Jim, Just installed KT66's, works fine, best amp ever !!  Tomeu C. (Spain)  

FM-5E3DP - Just finished three days of tracking with my Frenzel Deluxe Plus in my home studio. Since drums are in the same room I used the adjustable line out through a direct box and was able to dial in some great tones. Fun and versitile amp! Thanks, Dietrich P.

​

FM-5E3DP  - Hi Jim, This amp sounds like the best guitar tones I've heard over the past 50+ years of listening to music. On my Nashville Tele and Jensen Alnico's...I just can't stop playing! So many songs, so little time. Very inspiring. Thank you for beautiful tube tone. Curtis Popke (Round Rock, TX)  

FM-5E3DP - Just finished three days of tracking with my Frenzel Deluxe Plus in my home studio. Since drums are in the same room I used the adjustable line out through a direct box and was able to dial in some great tones. Fun and versitile amp! Thanks, Dietrich Pfeifer 

FM-5E3DP/525 - Well I can’t begin to tell you what an amazing amp it is. All I wanted at first was a nice clean loud enough clean tube sound. I am really glad I got the high gain JCM800 upgrade. The 800 sound carried me for years so to have that along with the clean F side is beyond words. Now they are both at my finger tips. I love the construction. You guys are masters. Thank you again and again. Cheers, Ivan D. (California)

FM-5E3DP525 "Deluxe Plexi 525" - Well if first impressions mean anything I’m impressed. This little thing sounds great. Nice tube tones from jazz to blues to rock. You can easily dial in the perfect breakup (I’m a Blues player) and you’re set. Step on a pedal and you get even more. I have an ABY box to toggle between channels or combine channels (highly recommended). I must also say these are a screamin’ deal that sound every bit as good as many $2000 amps I’ve owned and that’s no BS. Love all the features, Master Volume (excellent), wattage settings, edge control and line out. Most importantly…. The tube TONE is excellent!! Just a heck of an amp at a heck of a price!! Thanks Guys, Duke W. (Arizona) 

FM-5E3DP/525 -  Amp received! Beautifully packed and beautifully built! It sounds glorious! Thank you very much. This amp is awesome! - J. Stokes(Florida)

FM-5E3DP  - To Frenzel and Company: I just want to drop you a line regarding my Frenzel Deluxe Plus Amp received 3 days ago. It is every bit the amp I hoped for and more. All of the superlatives in other customers' reviews are true. I may never use my other amps again. Thank you for building a fantastic product. All the best to everyone at Frenzel! Thank you, Bob C. (Florida)

FM-5E3SD/100 - Hey Jim, Gotta say, this is one cool amp! I dig the tones I'm getting from it! I've recently had a few custom amps made that I just wasn't happy with, and then I went back to my trusty Frenzel DP3 that a bought several years ago and I just loved that sound!! My only problem was headroom, but tone was amazing! So I decided on the 100 watt version of the SD! I'll never have to worry about tone and/or headroom EVER!! I love what you do especially for folks like me on a budget. It's definitely great being part of the Frenzel family!!! Jarrett B. (Louisiana)

FM-5E3 DP - Hi Jim, been meaning to write a review but you know how it goes... I love the amp and its enormous versatility. So far I haven't gigged with it, but its the centrepiece of my practice setup. I've got a drum machine, a pedal board and the line out goes to a simple mixer. I can put any set of tubes into the Deluxe+ that I want and play any hour of the day or night. My wife and neighbours love you for making it!!  Cheers, Peter R. (Australia) 

FM-5E3DPR/6SL7 "Deluxe Plus Retro"  Dear Frenzel Team, THANK YOU! This amp sounds amazing. My Strat and Tele have never sounded better!! The Gretsch is almost dialed in as well. I can’t say enough about the tone of this amp. Even my wife walked into the music room 2 nights ago and said, “wow, that sounds awesome” Gretsch 5422TDC FSR + Frenzel F input + EXH Holy Grail Nano Reverb + MXR Carbon Copy Delay + THD 2x12 cabinet makes for an impressive Sleepwalk rendition. Again, thank you! Brian M. (California)

RB -100  Hi Jim, There were not a lot of reviews on the Retro Bassman 100 when I purchased it, so I wanted to share my experience. I have been using the Retro Bassman 100 for bass and guitar, and the tone has an incredible 3D quality.  As you might remember, while I was waiting for the RB-100, I ended up purchasing a Eden 1200 bass amp because of a gig I had to do. The Eden 1200 (Minnesota made version) is at the high end of performing bass amps. When it comes to comparing the two I find them to be equal in sound abilities, in their own ways.  The Retro Bassman 100 with the tube rectifier gives a rounded sound that is very articulate in how it represents effects.  The Eden (which has a 2 tube preamp) can't even come close to giving the same tonal quality, in any way shape or form.  On the other hand the Eden has a punch the Bassman can't come close to, even with the solid state rectifier. The Eden 1200 is an 800 watt amp in stereo mode and 1000 watts in mono mode at $2400.  The Retro Bassman 100 is a 100 watts at $1400 with all the bells and whistles.  Both amps push both my bass cabs at the same time (Bergantino HD112 and a Bag End 112) equally well.  The bottom line is that between these two amp there is no tone I can not get, where for the price, the point to point and no circuit board construction the Retro Bassman 100 has been a far superior purchase.  There are no words I can use which can describe the varied tones I get out of this amp.Then, there is using the Retro Bassman 100 as a guitar amp.  There is only one word that comes to mind, WOW.  All of the qualities which hold true for bass use go true guitar use. What I like most about it is that I get incredible feedback at any volume level.  Compared to Mesa Boogie, Fender and Orange guitar amps I have owned, the tonal qualities of the Retro Bassman 100 at lower volumes can't be beat, where the amp can still push really high volume levels.  It is like getting into a high performance car that drives really really fast on very curvy roads, compared to one that can only be driven fast in straight line.  I am using a number of different effect units including the Zoom B3 and G3 multi stomp effect units, Line 6 Pod XT live, Sans Amp Tri-AC , Digitech Valve FX, among other dedicated effect units.  They all sound incredible through the amp.  Next I am setting up my iPad with Radial Reamp, an Apogee One, and Jam Up Pro, Ampkit, and Bias apps to see how they perform with the amp in live use.  All of my guitars electronic systems are customized to the max.  All copper shielded, elaborate ground systems with grounds going from the input jack to everything (including hard soldered to the pickups), and quality pots, caps and wire.  I do this to allow the pickups to hear better.   A guitar or bass setup this way allows a quality amp abilities to really shine, and the Retro Bassman 100 really takes it to the next level.  I have used other boutique amps that can perform equally at the guitar level, but not at the bass and guitar level and definitely not at the price.  Very happy with your product. Rick K. (Sacramento Calif.)

SB-100 COMBO Hi Jim, I bought used a 2012 Frenzel Super Bassman 100 2x12 Combo the other day. I had few questions about the amp and I had immediate responses from Frenzel Tech Support, even on a Sunday. I like the amp a lot. I'm a boutique guy and have owned and currently own (Bad Cat, RedPlate) some high quality amps. And this Super Bassman was way cheaper. Yet there is something about the sound from the Bright channel and working the Presence that gave this beautiful top to clean sounds when I checked it out at a used music store. I think the Presence control and the Bright channel is what really makes this amp special. But I do love the cleans on it. This combo is a bit of a beast, but I couldn't resist it. I'll be playing a large venue in mid-December and will get a better sense of what it can do. Also the MV seems to work really well, too. And at 71 pounds, it weighs no more than a Vibro-King and less than a Fender Twin. Thanks, Mark Barna (Wisconsin)  

ST-800, Hi, It's been a year since I purchase my custom Frenzel Super Twin 800 and  I have to say that I'm in love with your Marshall channel. I like it a lot for playing break-up strat sounds.  Gerardo Regalini (Brazil) 

FM-5E3 DP - Hey Jim, Amp is here and really nice. I'll take a pic in the day time and send it to you. It looks great sitting on the walnut speaker cabinet. Thanks again...your service is second to none and I would happily recommend your business to anyone! Regards, Jason M (Australia)

​

FM-5F6MB - You guys did good!! - The Mini-Bassman arrived yesterday in excellent condition while I was at worship practice.  I built the cab for it over a month ago and was able to install the amp today and it sounds great!  This is my fourth Frenzel and never a disappointment with any of them. Many thanks, John W..(Indiana) 
 

FM-763  Dear Jim, How are you, family and employees doing now ? I have had the Super Vibe FM-763 for about 6 months now and have tried many tube combinations. During that time I have found many combinations all of which sound great in their own unique ways. This amps versatility is unmatched because of the very high quality components used. I am sure that you will not find this in any amplifier from a major manufacturer at any price. This amp delivers beautiful sounding overtones and harmonics, so much that I often let chords sustain and enjoy these absolutely beautiful sounds. 10 years ago I never imagined that my playing could sound this good. I mostly play with the M channel at about 7 and the F channel at 3. This gives it a very nice fat Marshall sound which I completely love and enjoy. This amp is an electronic work of art from the design stages until the final build. From this I conclude that this company absolutely loves what they do, true pros. For me the search for great tones is completed. I give my strongest recommendation to Jim Frenzel and Company as I truly believe you cannot do better anywhere else. Thank you Very Much and Good Luck To All At Frenzel Tube Amps. Donald K Bazille (Thailand) FM763SVR 

FM-763 - 1.5 years later.   Dear Jim, These days I am getting a lot of compliments on my guitar playing, but I think it is the absolutely beautiful tone that is getting the attention. I have tried a lot of different tubes in this amp and have settled on the following ; Preamp tubes are 1. Sylvania 12AX7 2. Sylvanis 12AV7 3, GE 5963. Trem and reverb tubes are 2 ea 12AX7 Shuguang and 1 Sylvania 12AT7. The rectifier tube is the original JJ 5AR4 and last of all 2 fantastic sounding NOS Tesla (not JJ) Mil Spec KT88s. I am not real sure how much my playing has improved, but this amp's tone cannot be beat.Thanks Again For Such A Superior Product!  Donald K Bazille (Thailand) 

FM-5F6MB - Jim and Team Frenzel, et al...Privileged to own three of your guitar amps. Started with a Deluxe Plus
Vibe...I picked up on ebay...using KT66's  du Tung Sol.  Best amp I've heard.  I've built amps, fixed amps and modded amps since the 60's.  Got pretty much THE amps. My vote is to award JIM the Western Electric Emeritus. I now have his Mini Bassman (which I dig in the Jim Marshall mode) and another Frenzel Deluxe Plus Vibe (which I dig in the F mode)...all with KT66's...Genalex and Tung Sol.  I play with a cord. A wood tele and two 12" Marshalls,  stacked.  Weber Alnico and Jensen Ceramic. JF, From one old radio guy to another...hey, good job.   yo ron  - Ron J. (Oklahoma)

FM-5F6MB  - Played my first gig with the 5F6MB last night, blues&rock - what an improvement over my last amp! Sent it thru a 112 Weber spkr, I use 2 pedals:  EH echo + overdrive. Using a single-coil guitar (strat), F input is the place - Using my Les Paul, it's a mix of F and M. The M circuit removes some of the bass frequencies that come with humbucker PU's + bassman circuit, reducing the 'boomy-factor.' Tone is still there, I like the balance by setting them half & half F&M - sounds great. - Regarding  tubes in V1 preamp position...12AU7/ECC82 delivers less clip at high gain/master settings, good for jazz or anything clean - 12AT7/ECC81 or 12AX7 delivers more clip, better for blues/rock. - Seems like the 12AT7 is just right for me, at this point.  Robert O. (Oregon) 

FM-5F6MB - Hey Frenzel Team - Purchased a FM-5F6MB Mini-Bassman about 4 months ago. Since then I've gigged indoors and outdoors - sounds great with my 1x12 cab, LesPaul, drive pedal and touch of delay. Clean on F-channel with bright-pull engaged was pure&smooth at the blues festival yesterday. An outdoor venue - set master at 3/4, gain at 10:00, bass down & presence up - exactly what I was looking for. Surprisingly loud, fit in the mix with full 'Fendr' tone + sparkle. My thanks to Jim and the Frenzel crew - this light-weight amp is affordable quality. Robert O. (Oregon)

FM-5F6MB  - Man, this thing is AMAZING!   Does everything I want it to, and then some.  The low end response is amazing.  Completely Satisfied, and looking forward to taking it out on gigs.  Amazing work, folks!   Amazing!  Best, Brad R. (California) 

FM-5F6MB - Dear Frenzel Amplification, I received the Mini Bassman Very well packed and built like a tank. After trying different combinations of tubes I found the three 12AX7 tubes, two 6L6GC power tubes and a 5U4 rectifier tube for a little more sag. The 5F6A Bassman input sounds excellent, the Marshall Plexi input sounds excellent also. When I use an AB switch to combine the inputs I discovered Tube Amp Nirvana, absolutely stellar tone to my ear. I added the Attenuator switch which comes in very handy. At the full 40 watts, this little amp is really loud. I am playing the amp through a close 2X12 enclosure with 2 Celestion Vintage 30 (16 ohm) speakers in Parallel. The amp sound great with Semi-Hollow guitars, Fender Strats, Gibson SG, Fender Telecasters. Single coils, humbuckers, P90s, Seymour Duncan rails. The amp responds very well to all types of pedals. If you are looking for a compact head, with a lot of versatility, look no further. Thanks Frenzel - Joe V.  (Ohio)

JF-5A3RD  Hi Jim, Got the amp JF-5A3RD  yesterday.  Your care in packing was as good as I have seen.I let the tubes warm up for about an hour and have played it for about an hour.  I am VERY impressed with the old school Jazz tones I am getting on my Mann 5 string electric mandolin. I will write a more complete review in a couple of weeks.  Let me say thank you for this wonderful piece of gear! Pete M.(Washington)

FM-5A3SD - Hi Jim, I just want to drop a note of thanks for the FM-5A3SD amp you built me. It sounds better than I hoped for! My Super Retro Deluxe (6SL7 preamp) is gigging regularly and is a joy! Thanks again, I couldn't be happier! Christian S. (Washington) 

FM-5E3SD - Hey guys, I just bought another FM-5E3SD Super Deluxe-this one off Ebay.(why would somebody get rid of one?) This makes 3 in my studio, 4 on stage as our other guitarist has one. The best tone machine on the planet - I know it is for me, and has made believers out of those in earshot. My original has been flawless on stage and studio since day one over 3 years ago. Thanks for making killer amps affordable. Leon Taylor (Oregon)   --- Hey guys just an update. 6 years of gigging stage and studio, this bullet -proof Super Deluxe is still flawless. The Frenzel does a few things no other amp I have ever played on could do #1. With pre-gain maxed, I can still play "clean" the most touch responsive pre-amp ever no pedals needed. #2. The sweet spot is found at every volume. I assume this is some kind of Voodoo. #3. The amp can be played at full volume ... the chance that is actually a thing are all but gone, but I have done it twice with my 1x12 40 watt KT88 driven combo. It only sounded like itself -only...more so. #4. The line out works well and sounds like the amp. Clean, quiet accurate reproduction of the great tone. Many a sound guy has started to mic my amp, I plug the line out into a direct box in it's place and "Perfect guitar tone" #5 Best Effects loop ever. I have owned amps that cost 5 times as much that didn't do ANY of these things. Thanks for a great amp.  Leon Taylor 12/28/2017

FM-5E3 SD - "Hi Jim, Love this amp - everyone who plays it is amazed at the touch and tone and all jaws drop at the price. Keep on building!" Russ R. (Texas)

SS-4772 - Thanks Jim, The amp sounds absolutely amazing, this is the best sound I ever had at home. Fantastic! Darek O. (California)  

SS-4772 - Dear Mr. Jim Frenzel, Your SS-4772 Super Stereo amplifier is nothing shy of epic. I am so thrilled, so happy, so blown away by your amplifier.  Thanks for integrating old school technology with new school systems compatibility.  This thing works great with my Apple iMac, my Samsung BluRay DVD, and my Samsung TV - and with no preamp required for these devices! It also works fantastic with my old school Technics 1200 Mk2 turntable.  My pristine 70's vintage Pioneer CS-99A speakers did a instant hand shake with this amp as if it was an old long lost friend. I am so pleased with  how this amp clearly transfers  digital iTunes music to a whole new world of old school analog tube sound.  Maybe it's the old school technology with a tiny bit of new mixed in to it... whatever the case my be, you have hit the nail on the head.  You have designed an old school analog tube amp that will transform the sound of digital recorded music to the way it should sound.  I'm amazed, I'm blown away, and I am so happy I chose your company to build my amp.  I received my amp last Friday. I have locked my doors, turned off my phones and email, and signed myself out from the outside world for a week while I process the prowess of this amp. A great super clean sounding tube amp at a price I could afford. Way to go!  Sincerely, John K. (Florida)

SS-4772 - Hi Jim, Thank you again for this wonderful amp. The best I ever had. I sit now and listen for hours, something I haven't done in decades..Darek O. (California)

FM-5E3 DP Jim, Just a note to say that the amp you built for me (deluxe plus) is perfect! I mostly play a Tele partscaster with Don Mare pickups. This seams to be the magic combination I have been searching for. The tone is great. It is small and light. It plays well with my pedals. I have installed it in a wood cabinet (photo attached). I did change a few tubes. I have a Phillips 5R4GY in the rectifier and RCA 6072 in the 1st position, amperex 12ax7 in #2 tone, and RCA 12ax7 in the #3 PI. The 6l6 are still the JJ. Anyway thanks for the great work! Alan B. (Texas) 

FM-5E3 DP - Finally arrived on Friday. Custom built, hand wired Frenzel Deluxe Plus. So far I think it is the best amp I've ever play through. I keep changing speaker combination and it still kick's Ass. 2x10,1X10,1X12,2X12 and any combination... The F preamp and the M preamp inputs are great. Manage them with an A/B switch Greg W. (New Jersey)

HBX-AC15 - Hi Jim, My Sweet 15 arrived today, safe and sound. I got it up and running and have played it for 45 minutes or so. My initial impression is wow, what an incredible range of tones this thing has. I haven't attached my pedal board to it yet. I was just playing it straight and dry with a strat and les paul.  Lots of exploring to be done here, but I can tell already that it has incredible clarity of tone. This amp is really going to cut through the band mix. -- (9months later) I have really been enjoying my HBX-AC15 over the past nine months. Thanks, William E. (Canada) 

HBX-AC15 - Frenzel Team - Thanks so much for the Sweet Little 15, the best tone I have heard. I have owed many, many amps. Jonathan C. (California) 

HBX-C15 - Howdy. the HBX-AC15 was delivered today. Yes, you guys did great. Thank you. I had to wait a little while to get it home, and it will take a little while longer still to try a couple of different cabinets and with various guitars. My first reactions are only positive. It's terrific, and I suspect I will continue to find great things about it. I really like the implementation of the controls and the way gain structure is set- not too much, not too little. The push-pull pots are a great and highly usable idea. Love it. Great work!  Thomas C. (California)

FM-5E3 DP -  Dear Jim, You wonderful amp has arrived and has enjoyed many good hours of testing--it passed with flying colors! Thank you for sharing your excellent work with me. I wanted to pass on a few pics of the cabinet I made for it.  I love the way it all turned out. Cheers, Ben W. (Florida) 

FM-5E3 DP  - Hi Jim, finally found the time to build a cab for the 5E3 DP, which I bought from You in 2010! I made a lightweight spruce-cab with the shape of the old Standel amps. In spite of the JBL-120 the weight is only around 17kg. Of course it sounds great! Helmut H. (Germany)

FM 5E1 - Hi Jim!  I love the old FM 5E1 that I've got! Cheers! Richard A. (Arizona) 

FM-5E1SS - Hi Jim, First gig in 2018. The line-out on the back of the Retro Frenzel Champ Super Sportster is amazing.The rig does wonders for my back. Who wants to carry around a Marshall stack? This one fits in the trunk of my car and the sound techs adore it!! Greetings from Holland guys. Colin W. (Holland)

FM-5E1BF" Dear Mr. Frenzel, My long time friend and brother in arms, Hein does have a couple of your amazing amps. For my birthday he presented me with a Champ by your hand. I'm absolutely over the moon with this little amp. Makes my Custom Shop Telecaster, by John Page, sound magical. Can't believe how loud 10 Watts could be. From the Netherlands I wish you a merry Christmas. First Lieutenant Colin W. - (Volkel AFB, the Netherlands)

STS-88  Thank you Jim , I really do love the tones this amp produces - the Edge boost is a very nice feature and I will find good use of that in my playing. This amp tunes  is very reminiscence of the Rivera Amp tones  I have loved and used over the years. I look forward to getting this baby out on the gig.  As a professional Guitarist since the age of 17, I have pushed thru all the commons in pursuit of the best tone for me. That is what lead me to building my own guitars and later launching my own guitar company over twenty-three years ago. I started playing a  Mesa Boogie in 1979 and had owned many combos and "Refrigerator Racks" of the  late 80's. Then moving back to combos with Rivera Amps in the late 90's and I was pretty happy. A few years ago I wanted to go stereo again( without the refrigerator).  I talked to all kinds of boutique amp designers every year at NAMM, then I found Frenzel Amps a few months ago. I talked to Jim about what he had in his line with the features I was looking for and there it was-  the STS-88. Several other amp designers had wanted three times as much to do what I was asking for!  My amp arrived a few days ago and I  put the amp thru it's paces. I found that the tone of the amp was rich and lush as I had come to expect from the Riveras'. One feature that I really dig is the "Edge" boost.  The STS-88 has great harmonics and a pallet of color that put a smile on my face! With the custom cabinets I designed this amp really sings.  I  run my effects through the front of the amp and use my  pedals to give me crunch and overdrive tones.  I find that  the STS-88 really responds well to them all. As a guitar designer this amp really shows off the tone of my instruments which complements what I do - and again, that puts a smile on my face! As it does to those who hear me play! Thanks Jim, you hit this one outta the park! Touch Singleton (California)

​

JF-B45 SBB - Hello Mr. Frenzel: Received the Super Bassman/Bluesbreaker a few hours ago.  Awesome packing job by the way.  I put the tubes in right away and let it warm up.  I have not stopped playing since.  Amazing sounds.  I can’t describe the tones I’m getting out of this.  Its putting my Marshall to shame.  And by the way a Marshall Class 5 Head is an awesome sounding amp.  But this does everything.  So many tones.  And tube options will make the tonal options infinite.  Thank you so much.  I need to get back to work but I can’t stop playing.  Thanks again. Steve E. (Ontario, Canada)

SS-4772 - Hi Jim, Hope you are well, many thanks for building this awesome amplifier for me, it arrived safe and sound thanks to the excellent packing. I had never heard one but took a chance due to the great reviews for your amps. on your website and elsewhere. I'm very glad I did too, the power, tone and clarity is just amazing and I can't believe how effortlessly it drives the Kef Chorales, they've never sounded so good even without new crossovers!  The Marantz CD63se sounds fantastic through the amp. I'm now thinking of buying a Musical Fidelity M1 DAC to further improve the cd analogue output for the amp., I think it deserves the best possible signal.Nice to see the 1% tolerance resistors that's real quality, they look like 2w carbon to me? Everything looks just as good inside as out, very neatly laid out, you are right to be proud of your products! Thanks again for building it for me, I wouldn't hesitate to recommend you to friends and family. Pete C. (United Kingdom) 

HBX-AC15 - Just blown away! Proud owner of a AC15 HBX ! Tone,tone,tone!!! Many thanks to Jim and the whole family! I waited on purpose to see if this amp was gonna make it thru the "Honeymoon phase" before posting a comment.Safe to say its a keeper! The cleans are perfect, the dirt channel is old school and there seems to be quite a bit of tweaking for various shades in between. To be honest, I haven't felt this good about turning on a amp and plugging in my guitars in a long time. Keep doing the fantastic work you good people do!   Dan F.(New York)

FM-DP1 - Hi Jim got the preamp after the UPS man left it at the neighbors house, but my wife tracked it down. You  sure  know  your stuff.  It works great!  Adds headroom, great volume control, awesome tone. Just what you said. Dwight H. (Colorado) 

FM-DP1/6SL7 - Thanks Jim and crew. What a cool piece! Love it! Love the DP1! Exactly what I was hoping for. I have a collection of various vintage Peavey steel amps and guitar amps for different gigs. Church, barroom, big, small, need to have multiple rigs set up sometimes. The DP1 lets me get my favorite preamp tube tone with any of my 5 PVs. Just fantastic! Octal preamp 6sl7 goodness on any amp I need. I love tube on front end/solid state on back end. Steel guitar needs clean power or it gets nasty, the DP1 gives me that wonderful bouncing off the strings feeling that tubes give, and the PV does the rest and fills the room cleanly. Love how I can grease it up a bit by tweaking gain and master.  I use your Retro Deluxe to record with and for certain gigs. DP1 is gonna be my main live secret weapon now! Gonna keep Retro 5a3 for studio work. DP 1 is so easy to pack in my bag. What a great product and service you do. Super value. Love my sound! Tommy C.(Florida)

FM-DP1 - Hi Jim, I have received the FM-DP1 and am enjoying getting to know it. It’s remarkable how many options of warmth I have available to me now. I am using an Acoustic Image Clarus Series 4 (not sure if you are familiar with it) but the ¼”instrument in seems to be a very low impedance? Meanwhile, by happy accident - the xld channel is perfect, gives the sound(s) I love. I seem to use far less power and not have feedback issues etc. I now feel some relief that I had the happy accident of requesting an xlr out. I am very grateful to you for the quality work you have done here Jim.. Thank you for the quality preamp, David O. (New Jersey) 

FM-DP1/800 - Hello there... I know its been a long time since we had spoke via email. Just to let you guys know I love this FM-DP1 preamp. I'm have so much fun with this preamp...great product. When I expand system I will be using your product and also I do tell others about Frenzel amp. Erik C. (California) 

FM-DP1  - Jim & Crew, -  All I can say is WOW!! This preamp sounds awesome with my Pedulla 5 string bass. I'm using a Y cable combining F&M gain  and the tone is incredible! I have played most of the high end pre's out there (I'm an old guy too)and this pre smokes all of them, not to mention the build quality, absolutely top shelf. I never really thought I would find that sound I had in my mind,,now I have. Thanks to all of you and your outstanding artistry and craftsmanship! Almost forgot,,This thing is dead quiet,,UNBELIEVABLE!!!  Thanks again,  Jeff R. (Ohio)   

FM-DP1 "Deluxe Plexi 1" Preamp -  Finally got a chance to put it through some paces this weekend. Used on a P-style bass for a recording session. Sweet! Many thanks for the excellent product. Al S. (New Mexico)  

FM-DP1 - Hi Jim,  I've received the preamp and am very pleased. I'm sure I'll discover more as I experiment, but It does what I hoped it would in softening and refining the attack with a solid state amp. Still clear and articulate, but without the clinical starkness that often comes with solid state. The care with which you build your products comes across in everything including the shipping. Thanks, John H. (Toronto, Canada)

FM-DP1 - "Warm Smooth Bass Tone Found - Melted Chocolate Flowing Over A Warm Brownie" - Dear Frenzel, I purchased an FM-DP1 about 3 years ago, and have used it to sculpt my guitar tone with great success. However, one weakness that I always seemed to run into when I was recording tracks, was getting the bass to have that warm, round, and smooth “thickness” that seems so elusive. I tried all sorts of options without real true success. I would have to run the bass through amp simulators to even get close, but it was never quite right. I could not find that tone. I even bought another bass to see if that would help, and it didn’t. So I began to explore tube-based Direct-In boxes, but found them to be too expensive. I then began to explore a DIY option to build my own tube-based DI box, but that wasn’t easy either. This morning I was going about my business, and had the Tube DI on my mind, and suddenly I had an idea. “Wait a minute, my FM-DP1 is all tube, and it is a preamp, surely, I could run that Direct-In to my Focusrite interface.” So I did just that. I set up a ProTools session where I ran tests on the Focusrite’s DI, the FM-DP1 Fender voicings, and the FM-DP1 Marshall voicing. I did the tests with both of my bass guitars: A 2004 Ibanez Iceman with humbuckers, and a 2015 Fender Squire J-Bass. In about 3 seconds I heard the tone I had been longing for. There it was in its glory! I achieved that thick, warm, smooth and beautiful tone immediately when employing the Ibanez through the FM-DP1’s Fender voicing. Gain was minimal, but if I wanted dirt, it was easy. The Fender J-Bass gave incredible deep throbbing, but rich and smooth tones with more detail (like pick attack, etc.), but both sounded spot-on. It was like melted chocolate flowing over a warm brownie. The FM-DP1 isn’t really marketed this way (as a Direct-In), but believe me…it sounds majestic, AND it just saved me about $745 on a tube Direct-In box. Thanks Frenzel!!!
