The Revv G4 Red Channel Preamp/Overdrive/Distortion Pedal Anniversary Edition is a high-gain distortion pedal built on the red channel of Revv's Generator 120 tube amplifier. It is a special cosmetic version of the standard G4: released in 2024 with floral graphics, it is identical in circuit to the regular pedal1. Premier Guitar listed it at $229.00 USD in December 20242.
What it does
The G4 is an amp-in-a-box style pedal: Revv describes the circuit as an "Organic 'amp-in-a-box' pedal based on the G120 - Red channel"4. Delicious Audio's Paolo De Gregorio calls it "the pedal version of the red channel of the company's 120 Generator tube amplifier," an amp-voiced pedal based on a tone used by touring and recording guitarists1.
Revv says the G4 can "Run the G4 into the front of any amplifier to use it as a traditional high-gain distortion pedal"5. Delicious Audio adds that it works with combos, heads, pedalboard rigs, in effects loops, and with cab modeling1.
For gain shaping, Premier Guitar notes "this finely tuned circuit offers gain variation with its 3-position aggression switch"2.
Where it came from
Revv built the G4 around an existing amp design: the pedal's circuit is based on the red channel of the company's Generator 120 amplifier, a finely tuned circuit that offers gain variation through its 3-position switch2. The Anniversary Edition carried a list price of $229.00 USD2.
The Anniversary Edition followed in 2024, part of a pair with an anniversary G3: Delicious Audio reports the 2024 G4 Anniversary Edition was identical in circuit but carried floral graphics1.
How it compares
- The standard G4 shares the same circuit; the Anniversary Edition differs in graphics only1.
- The G4 V2 Canadian Edition is Revv's current amp-in-a-box version based on the G120 red channel4.
- The G3 sits alongside it in Revv's Generator-based line, with the G2 covering lower gain and the G4 covering higher gain levels6.
- Revv also makes heavier-leaning distortions such as the Northern Mauler for players beyond amp-in-a-box voicings.

No. Delicious Audio reports that the 2024 Anniversary Edition of the G4 is identical in circuit to the standard pedal, differing only in its floral graphics. The pedal remains based on the red channel of Revv's Generator 120 tube amplifier and carries the same three-position aggression switch for gain variation.
What amplifier is the G4 based on?
The G4 is an amp-in-a-box style distortion based on the red channel of Revv's Generator 120 tube amplifier. Performer Mag's reviewer described it as Revv distilling the red channel of their high gain Generator series amps into a pedal, and Premier Guitar notes the finely tuned circuit offers gain variation through its three-position aggression switch.
