Standard Features:

  • Normal (Type F) Bright (Type M) inputs with separate preamps and Gain controls with Bright pull switched.for the unique smooth Fender Bassman warm tones or the Marshall Plexi great high mid-tones....or you can use an AB-Y switch and create your own distinct tones.

  • Bright pull-Switch on F and M Gains.

  • Master level control so you can crank the GAIN's up and overdrive the preamp without overdriving the output tubes.

  • Presence control  - used to adjust the high-frequency response and damping factor of the power amp section.

  • Boost - Unique NNFB "Edge" boost switch on the PRESENCE control that transforms the power amp section into a No-Negative-FeedBack style amp for soaring dynamic leads. 

  • Effects Loop - pure tube buffered serial effects loop designed to perfectly match the low impedance solid-state pedal levels with high impedance tube levels.

  • Line Out - post output transformer LINE OUT with LINE OUT LEVEL control for recording or driving a power amp, Auto switched internal load to simulate speaker if speaker is  not plugged in. Inject great tone directly into the PA system with the Speaker Simulated Direct Interface.

reviews

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.

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) 

Hi Jim, Here's a followup on my gig at a large venue with Frenzel Super Bassman 100. I ran Bright Volume at 6 and Master Volume at half and had a really nice clean tone with some grit and then added pedals as I chose. Had a few compliments on the sound, too. Thanks. Mark Barna
