A tube guitar amp head with tight, gated high gain.
With modern amplifiers, compact size doesn’t have to mean compromise. The Revv Amplification Generator G25 25W tube guitar amp head proves it, delivering the brand’s signature Blue clean and Purple high-gain channels in a portable format built for studio, stage and silent recording. Powered by two 6V6 power tubes and three 12AX7 preamp tubes, the G25 blends responsive tube feel with modern control features including selectable 5W/25W operation, onboard reverb and a built-in noise gate. Two Notes Torpedo technology with reactive load and IR cabinet simulation enables direct recording, silent practice and FOH integration without a speaker cabinet. Add independent master volumes, MIDI capability and a programmable footswitch, and the G25 becomes a compact yet fully professional solution for players who need versatile tones without sacrificing feel or control.
Signature Blue and Purple Channels for Clean Tones and High-Gain Precision
The Generator G25 centers around Revv’s proven dual-channel platform, pairing the articulate Blue clean channel with the aggressive Purple high-gain channel. A shared 3-band EQ keeps tone shaping intuitive, while independent Bright switches allow fine-tuning for different guitars and pickups. The Blue channel’s proprietary Wide voicing expands headroom and clarity, while the Purple channel offers three Aggression voicings alongside a Fat switch for shaping modern high-gain textures. Independent master volumes per channel make switching between rhythm and lead tones seamless, giving players precise control whether tracking in the studio or moving through a live set.
Two Notes Torpedo Integration for Silent Recording and Direct Output
Built-in Two Notes Torpedo technology transforms the G25 into a complete recording and direct-to-FOH solution. A reactive load automatically engages when no cabinet is connected, allowing silent operation without compromising tube response. The onboard virtual cabinet section includes a six-position rotary selector, headphone output and adjustable level control. Additional editing via USB expands access to DynIR cabinet simulations, EQ, virtual power amp options and reverb processing. Whether recording at home, running direct on stage or practicing with headphones, the G25 delivers flexible routing without the need for additional gear.
Power Scaling, Reverb and Noise Gate for Modern Workflow Control
Selectable 5W and 25W operation makes it easy to dial in power tube saturation at manageable volume levels. A bypassable digital reverb adds depth without external pedals, while the built-in noise gate keeps high-gain tones tight and controlled. A transparent buffered serial effects loop supports modulation, delay and time-based effects without compromising tone. Together, these features create a streamlined signal chain and consistent performance across rehearsal, recording and live environments.
Compact Tube Platform With Professional Connectivity
Despite its compact footprint, the Generator G25 delivers professional-level connectivity and performance. MIDI control supports program change and continuous control functionality, while multiple impedance outputs accommodate a variety of cabinet configurations. Rear bias test points and tube fault indicators simplify maintenance, and high-quality custom transformers help maintain consistent tone and response. Housed in a durable birch headshell and weighing just over 15 lb., the G25 is built for portability without sacrificing the feel and dynamics players expect from a full-size tube amplifier.
Ready for Studio, Stage and Silent Performance
From silent recording and direct-to-FOH setups to traditional cabinet-driven performance, the Generator G25 adapts easily to modern guitar workflows. Its versatile two-channel architecture, integrated Two Notes technology and flexible power scaling make it equally at home in studio sessions, rehearsals and live environments. Compact yet powerful, the Revv Amplification Generator G25 25W tube guitar amp head delivers professional tube tone and modern flexibility in a portable, stage-ready platform.
