Details:

It features a push-pull cathode-biased dual 6V6 power section which happens to be my preferred design, as seen in the SWAT AST for example. No, this was a completely new circuit that features hand-wired components mounted on turrets the board and with tube sockets controls all chassis. Some later buyers of this model complained about a weak tremolo, but that's not the case here. This is an that needs a brighter speaker, and there are many good options.

Features a powerful drive channel with bass treble controls and clean tube-driven electronics reverb, tube tremolo, / middle EQ. If you want to know more, just ask me. The shipped with a boring Eminence model ING speaker which made the sound dark and little weak. Its a beautiful looking and wonderful sounding combo. I've had a lot of amps come through my studio, and aside from that cost more than twice as much this has been favorite.

And I couldn't. This beauty is a 2005 Gibson GA-20RVT Combo Guitar Amplifier with one 12 Jensen Blackbird Alnico speaker, the 100W version. So you can freely mix different pairs of the same type/brand of 6V6s. This is a non-master volume that conically perhaps most similar to bass man and it can get great blues overdrive when you crank.

But I need to downsize, so when went decide which one sell and keep tried find some difference between them. This was not a reissue, in spite of having the same model number as an old Gibson from 60's. And I'm a crazy speaker guy!, I have two of these Gibson amps and love them both. These tubes improve the treble response nicely.
