Revv Generator G25 25W Tube Amp Head

Revv · amplifier

The Revv Generator G25 is a compact, 20-watt two-channel tube amp head, effectively an update to Revv's earlier G20 with added headroom and modern refinements. It runs a pair of 6V6 power tubes and a pair of 12AX7 preamp tubes through oversized transformers, voiced around Revv's high-gain Purple Channel character. Built-in reactive load and impulse response technology, powered by Two Notes Audio Engineering, lets the amp be operated safely without a physical speaker cabinet connected, useful for silent recording or direct-to-interface use. It sits between the smaller G20 and the larger, EL34-driven G50 in Revv's Generator lineup.
