Overview:
​
The FRENZEL STS 3030 "Super Twin Stereo 3030" is the stereo version of our classic Super Twin series of amps. It was inspired by the Jerry Garcia's use of Hi-Fi tube amps for the classic Grateful Dead sound. It is very unique and comes standard with both channels voiced for the Fender Twin tones. Each channel features a separate volume, tone stack, and presence control which allows you to fine tune the sound just the way you like it.
​
The heart of any amp is the preamp…it generates the signature tones. The preamp in this amp is a killer tone machine like none you have ever heard. It has High-Low separate input jacks for each channel. This allows you to match your pickup output impedance and to use an AB-Y switch select either channel or both to create your own unique tones! Each channel has its own Gain Control with a Bright pull switch, a 3 Band Tone Stack, Master Level Control and Presence control with Edge boost pull-switch that reduces the negative feedback level to produce a boost in volume and a soaring uncompressed sound for dynamic leads. The combination of all these options generates a wide ranges of tones from Clapton warm to Van Halen hot!
​
No matter how good any preamp is, it can always be fine tuned an Effects Loop to create your own unique tones with pedals. So we added a passive buffer pure tube effects loop which matches low or high impedance pedals with the high impedance tube circuitry of the amp to eliminate tone suck and volume loss.
​
Each output stage comes standard with a pair of 6L6GC power output tubes. A 6L6/EL34 bias switch allows the use of EL34 output tubes. For the output trannies we chose a ultra linear pro audio grade that provides you with extended low-end Fender warmth and those incredible enhanced Marshall high mid tones. All the while, maintaining a perfect balance between the highs, mids, and lows. The trannie has 4, 8, and 16 ohm output taps.
​
For the power supply section we used an over-sized custom power transformer which provides great voltage regulation so that you don’t sag too much when you get on it hard. The high-voltage is filtered for very low hum by an equally large choke and four filter capacitors. We stayed with the Fender Twin choice of solid state rectifiers, but chose the newest type FRED ultra fast recovery rectifiers for tight dynamic bass response.
The amp is built on a compact 17” x 10” x 3” aluminum chassis and come with a retro steel mesh cage. All the parts in the amp are top-of-the line including polypropylene coupling caps, precision mica tone stack caps, metal film resistors, Alpha pots, Neutrik jacks, high voltage sockets, etc… This is a rock solid point-to-point hand wired amp….a real one of kind collectors item...designed to last for generations!
Standard Features:
-
Dual Channel - Each channel has separate Gains, Tone Stacks, Masters & Presence controls.
-
Channel 1 & Channel 2 Fender Twin smooth warm clean tones.
-

-
Presence controls - used to adjust the high-frequency response and damping factor of the power amp section.
-
Boost - Unique NNFB "Edge" boost switch on the PRESENCE controls that transforms the power amp section into a No-Negative-FeedBack style amp for soaring dynamic leads.
-
Line Outs - 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:
Hello, I have been using your STS3030 now as my primary amplifier into a pair of these loaded with Celestion A-Types for a few months now and I just wanted to say that I couldn't be any happier with the quality, design and sound of your amp. I know you guys get a lot of well deserved praise, but I just wanted to add that from top to bottom this amp is absolutely amazing and fulfills all my stereo needs and beyond. I will enjoy it for a lifetime. Thanks for all you do! Sincerely, John Davis (California)
