If you’ve been waiting for a tube amp that doesn’t force you to choose between raw power and modern convenience, the new G25 from Revv Amplification might just be your endgame. Building on the legacy of its G20 predecessor, this updated head crams a staggering amount of forward-thinking tech into a compact Tolex-wrapped chassis.
At the heart of the G25 are two meticulously voiced channels sharing a unified EQ, each designed to cover serious tonal ground. The Blue Channel delivers pristine, warm cleans that stay articulate whether you’re running straight in or stacking pedals.

Flip over to the Purple Channel, and you’re in high-gain heaven – tight, aggressive, and loaded with three distinct aggression voices that move effortlessly from old-school crunch to modern metal devastation. Independent volume controls for each channel make dialing in stage-ready balance refreshingly simple.
But what truly sets the G25 apart is how seamlessly it bridges traditional amplification with modern workflow demands. Thanks to its built-in reactive load and Two Notes-powered impulse response technology, you can run this amp direct via XLR and still retain the feel and response of a cranked tube head.

Despite its 20-watt rating, the revoiced power section offers increased headroom, giving the amp a bigger, punchier feel than its size suggests. A switchable low-power mode adds further flexibility, making it just as comfortable in a bedroom as it is onstage.
And with a transparent buffered FX loop, onboard digital reverb, tight noise gate, MIDI programmability, and included footswitch, this is an amp designed to handle the heavy lifting in any modern rig.
