"They make great class A hand-wired amps. I use a 40 watt that's switchable down to 20 watts. It's really an incredible amp! I've owned Fender Deluxes, Marshall JCM800's and lots of other amps, but this is the best one I've ever owned. I really love it"
--Jason Isbell (Vintage Guitar Interview)

"The Roaring-40 shines for it's overdrive, circuit design, a versatile set of controls and top-notch components"
--Vintage Guitar Magazine

"They brought it out to the NYC show and I couldn't let them take it back! A ridiculously well-made and great sounding amplifier"
--Jason Isbell (solo artist)

"These cats build the best hand-made boutique amps... I'm in love with it!"
--Mike Cooley (Drive By Truckers)

"...the Roaring-20 still beats out all the other amps I own, making it much easier to sell off the other amps in my collection!"
--Bill Stuart (amp collector)

"It felt like I was playing a baritone sax! The dynamic range of my playing has never been this pronounced"
--Mark Dziuba (Director of Jazz Studies, SUNY University)

“For my entire pro career I’ve been searching for the ultimate in true tone, but was just never able to “dial it in” completely in any of the off the shelf guitar amps. But, all that changed when I plugged into my Sommatone Roaring 40. From large concert halls to smaller club venues, the tone is so consistently rich and fat, and has the most true and natural tube sustain I’ve ever experienced. And the bonus… my smokin’ Roaring 40 gave me the ability to lighten up my pedal board, too. Quite simply, I’m hooked… thanks Jim!”
--Alan Grant (Primitive Soul)

"I've experimented with so many different amps in the studio and nothing compares to the versatility of the Sommatone Roaring 40. I finally found an amp that can do everything I want!"
--Evan (Dive)
Sommatone Roaring 20 & 40

These single channel "Class A" amplifiers are inspired by the tone and features of vintage amps. The combination of a well filtered power supply and original circuitry allow these amps to move some serious air, yet remain articulate no matter how hard they're driven – no mushy response here.

Tonally, the amps cover a wide range of sounds, from chimey clean to thick overdriven tones, and everything in between; controls are sensitive and interactive, yet any setting is exceptionally musical. Make no mistake - this is not a replica. You won't see this circuitry, build quality or tonal flexibility in any other amp on the market. Hear the difference.

The reverb circuit is unique as it's wired in parallel with the preamp versus series used by most amp manufacturers. Because of this, our reverb circuitry doesn't color or change the sound in any way.

Construction, Components & Features

The Roaring amps are constructed using true point-to-point wiring. By mounting all components directly to tube sockets, jacks and pots, we are able to ensure the purest signal path, maximum touch sensitivity and the least amount of tonal degradation. Our amps are handmade and extensively tested for tone as well as reliability.
