Sommatone Roaring 40

Post by beasleybodyshop »

long story short: the Drive By Truckers have been on heavy rotation on my ipod for the last few weeks. Great tone: good ol' lo-fi sounding southern rock. I was looking into the amps they use and found out they are mostly playing SF super reverbs and a Sommatone 40. After a search on Sommatone's website they describe the sommatone 20 and 40 as:

"single channel "Class A" amplifiers which 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"

...right. Ok. So when I hear Class A at the 20-40 watt range, Im thinking Vox AC type amps....so in the opinion of the group here would you say that these Sommatones are essentially hot-rodded AC-30s? Anyone have any experience with these? Just curious.

Without trying to start a "class" war, I've seen a number of places where people say the 5E3 is class A. Dunno, don't really care about class. Just suggesting another direction that "classic amp" comment might go.

AC30s don't operate in Class A either.

Many people believe that an amp is Class A if it is cathode biased.

Right. Not trying to start any flames here. I'm just curious to know if these amps are basically Vox topologies.

It was interesting to look 'round a Google search on this.

4- EL84 running a claimed 40 watts come from running very high voltages (SS rectifier as well). 2-knob reverb and 3-knob tone stack. Boost reported to work well with volume controlled from guitar.
