Revv G25 Tube Amp Head

The Revv G25: a lunchbox head that convinces on stage, in the studio, and in the bedroom without compromising on tube sound

The Revv G25 is proof that small size and big sound are not contradictory. With a fully analog tube signal path, a powerful 6V6 power section, and switchable 4W/25W output, this head delivers a rich, dynamic tube tone that works at any volume. Whether you're filling a stadium or practicing at night on your headphones, the G25 adapts without losing character.

The two channels are each designed with a distinct personality. The blue channel is warm, clear, and exceptionally suitable as a pedal platform thanks to its higher 25W headroom, which only breaks when you want it to. The purple channel is tight, punchy, and articulate, with three selectable Aggression voices that can handle everything from vintage crunch to distinctly modern lead tones and downtuned rhythm work. Independent volume control per channel ensures the perfect balance on stage.

What truly sets the G25 apart is its integrated Two Notes Torpedo reactive load and IR technology. Send a perfectly miked, mix-ready analog tube tone directly to an audio interface or PA, without a speaker cabinet. Combine that with a built-in reverb, a transparent studio-grade noise gate, and a dedicated headphone output, and you have a complete system in 7kg. MIDI-compatible with storage for 128 presets, controllable with any MIDI controller.
