From the vendor

Project overview

Modern high gain drive, that’s what the Revv G2, G3 & G4 pedals are known for. This is your chance to build your own version of this insane preamp in a box. Accurate OpAmps emulations of the purple and the red channel from the Generator tube head.

There is no need to tell you how good this thing sound. You can find plenty of insane videos on YouTube if you do not know them yet. You will find why it has been chosen as the best pedal of 2018 by multiple specialized media after trying it.

Introduction

To finish up the Revv pedal line up here comes Revolution II, based around the G2. Supposed to be pedal with the lowest amount of gain for everything from slight grit to hard rock. But don’t get confused by that, when cranking the volume and the gain it’s still pretty hot and can make some metal guys out there happy. Well at least it makes me very happy and I could totally crank it without getting oscillation or the need to add a buffer before getting rid of that. Actually, it’s the one I expected the less from what heard before in demos and surprised me the most once I had it in my hands. So you are not just building this to have all three but because it provides you with a lot of useful tones.

For the guys that have trouble with designing their own artworks but don’t want to have bare enclosures – ask for a faceplate, we already offering the, for Revolution III and IV.
