Older production amps were suggested to be sent back so they could be updated with this voicing. I have the speaker cabinet wired for stereo. Theres a vintage 30, and a lead 80 in the cab. Ive used this amp both live and in the studio extensively. Its super convenient having a stereo setup in one amp.Also, the foot switch allows you to blend between the blackface and plexi channels.. So there are a lot of unique tones in between the two channels. The item "Gerlitz Revelator Dual Amp G1 And 2x12 Cabinet + Road Cases" is in sale since Saturday, July 13, 2019.
