The REVV G2 Crunchy Drive is a medium-gain overdrive pedal from Revv Amplification, built to put the Green channel of the company's Generator 120 amp on a pedalboard. Revv describes it as an organic "amp-in-a-box" pedal based on the G120 Green channel, engineered to retain your guitar's natural acoustic characteristics, and developed alongside Nashville session guitarists to cover a wide variety of touch-sensitive sounds12. It joined the REVV G3 and REVV G4 in Revv's line of Generator-channel overdrives, and at the time of the announcement it was available for pre-order, due to ship sometime in July3.
Where the G4 distills the Red channel of the Generator 120 into a high-gain pedal, the G2 takes the lower-gain Green channel. Guitar Pedal X billed it as a drive rather than a distortion, with a bluesy, crunchy Plexi/Marshall-style voicing and lively, bright-edged dynamics3. Gearnews summed it up as a neat, medium-gain overdrive pedal with amp-like tones4.
Built from the Generator 120's Green channel
Revv's Generator 120 is a tube amp head, and its Green channel is the amp's lower-gain voice. The G2 is that channel in pedal form: Revv's product page calls it an organic "amp-in-a-box" pedal based on the G120 Green channel1, and Pedal of the Day's review confirms the lineage, noting the Green Channel on the amps is crunchy and touch-sensitive, "and that's exactly how the G2 behaves as well"6.
The contrast with the rest of the Generator line is the point. The REVV G4 is built from the Red channel of the same amp, the high-gain voice789, while Performer Mag's review of the G2 describes it as Revv finding a way to distill the lower gain sounds of the Generation series of amps after the G4 had already captured the Red channel8. In short:
- G2: Green channel, lower gain, crunch and touch-sensitive overdrive13
- G3: the middle pedal of the trifecta3
- G4: Red channel, high gain7910
Revv says the G2 was built and designed alongside Nashville session professionals2, and that it can be used as an amp boost or a standalone overdrive, according to MusicRadar's launch coverage11.
The three-position toggle switch
The G2's defining control is a three-position drive switch that changes voicing and gain saturation1. MusicRadar describes it as switching between different bass response, saturation and gain levels11, and Guitar World's coverage frames the three positions as clean tone-shaping, touch-sensitive overdrive and classic tube amp tones12.
| Position | What it does |
|---|---|
| Off (center) | Pulls the clipping diodes out of the path for a high-headroom clean boost with active EQ2 |
| Blue | Touch-sensitive edge-of-breakup crunch2 |
| Red | Thicker, hot-rodded classic-stack saturation2 |
Guitar Pedal X's review gives a player's-eye view of the two voiced positions. With the switch set to Blue, you are in Blues Breaker and Blues Driver territory, and that is the default setting with the toggle up. The Red mode moves into raunchier Plexi-style territory, and the middle setting is essentially a significantly cleaner version of the Blue setting3.
"In the Blue position, you get a touch-sensitive tone with gorgeous musical breakup."
That Blue position is where the Green channel character lives: Pedal of the Day found the pedal provides clear, dynamic, amp-like tone to push a rig where it needs to go6.
What reviewers made of it
Reception across the press was consistent about what the G2 is and where it sits. Guitar Pedal X called it a lower-gain drive with plenty of headroom and range to suit pretty much all playing styles, a verdict the reviewer attributed in part to the That Pedal Show gang3. Gearnews concluded that players looking for a neat, medium-gain overdrive pedal with amp-like tones would find the G2 worth checking out4.
Performer Mag reviewed it as a Preamp/Overdrive/Distortion pedal, noting its three-way voicing control with red or blue modes and its lineage in the lower gain sounds of Revv's amp series8. In 2020, Guitar World reported a limited-edition Gold finish for the G2, which carried the same 3-position Drive mode as the standard pedal12.
Price and availability
The G2 launched in June 2019 as a pre-order at $229 in the US and £199 in the UK, due to ship in July of that year3. Guitar World confirmed it was available for $229 later that month13. A 2023 Thomann affiliate listing showed it at $192.00 (209.00 euro), so street pricing can come in under the launch figure14, and Guitar Pedal X's 2025 roundup of boost and overdrive pedals still listed the REVV G2 Crunchy Overdrive at $2295.
Prices here are as published at the dates given. The 2019 launch price and the 2025 listing are both $229; the 2023 affiliate listing is lower.

Questions
Is the REVV G2 an overdrive or a distortion pedal?
It is an overdrive. Revv describes the G2 as a medium-gain amp-in-a-box overdrive, and reviewers have billed it as a drive rather than a distortion. It sits at the lower-gain end of Revv's Generator pedal line, below the G3 and G4, which handle higher-gain sounds.
What is the difference between the Blue and Red positions on the REVV G2?
Blue is the default crunch setting, described by reviewers as Blues Breaker and Blues Driver territory with touch-sensitive breakup. Red pushes into thicker, raunchier Plexi-style saturation. The middle Off position removes the clipping diodes for a high-headroom clean boost with active EQ.
Which REVV amp is the G2 Crunchy Drive based on?
The G2 is based on the Green channel of the Revv Generator 120 amp. Revv calls it an organic amp-in-a-box pedal built from that channel, and reviewers describe the Green channel sound as crunchy and touch-sensitive, which is how the pedal behaves.
How much does the REVV G2 Crunchy Drive cost?
The G2 launched in 2019 at $229 in the US and £199 in the UK, and Guitar Pedal X still listed it at $229 in its 2025 overdrive roundup. A 2023 Thomann affiliate listing showed it at $192.00, so street prices can sit below the launch figure.
What other pedals are in the REVV Generator series?
The Generator pedal line is a trifecta: the G2 Crunchy Drive for lower-gain Green channel sounds, the G3, and the G4, which is based on the Red channel of the Generator 120. The G4 was later joined by anniversary and V2 editions with the same core circuit.
