Fat, Saturated Amp-in-a-box Distortion Whether you're playing your guitar through a combo, an amp head, or direct with a modeler, you can tap into thick, saturated, amp-like distortion with the Revv G4. Fans of the Revv G3, take note — the Revv G4 isn't an updated G3, it's the polar opposite. It's got the fat, full sound of a raging amp stack, and it pairs well with a variety of mid-forward boosts, overdrives, and distortions. In the words of Revv, “if the G3 is a scalpel, the G4 is a sledgehammer.” For the gargantuan tone of the Revv amp's Red channel in a pedal format, get the Revv G4 distortion pedal.Fine-tune your tone with three voicing options Guitarists at GearNuts appreciate the extra sonic flexibility the Revv G4 offers with its 3-way voicing switch. In the off position, it packs the same sonic character as a Revv amp's Red channel.
