Revv Generator G20 20-Watt 2-Channel Tube Head
Revv · amplifier
The Revv Generator G20 is a 20-watt, two-channel lunchbox-format tube amp head built around Revv's flagship high-gain Purple Channel voicing, offering increased tonal flexibility in a compact chassis. As the original entry point in Revv's Generator head lineup, it established the compact, Purple-Channel-voiced format later refined by the G25's added headroom and reactive load/IR technology. It's aimed at players wanting Revv's signature high-gain character in a small, portable head rather than a full-size multi-channel amp.
