Project overview

Modern high gain drive, that’s what the Revv G2, G3 & G4 ™ pedals are known for. With the Universal revolutions SMD, you can choose which of the three suits you the most and then build your own version of it in an easy, fast and fun way. Enjoy any of these insane preamps in a box! Once you try one, you will want to have the other two.

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 discover why it has been chosen as the best pedal of 2018 by multiple specialized media after trying it.

Introduction

Revolution II

Of the series, The Revolution II is supposed to be the 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 crank it without getting oscillation or the need to add a buffer before getting rid of that.

Build the Revv II if you want a sound that’s both warm and transparent, able to embellish the sound of your guitar while respecting its identity.

Personally, it’s the one I expected the less from what I heard before in demos and surprised me the most once I had it in my hands. Both dynamic and open, this pedal provides you with a lot of useful tones.

Revolution III & IV

As you can see, both pedals look very similar, not only by the controls but also by the components and the schematic; though they sound pretty different, they complement each other. In the words of Revv, “if the G3 is a scalpel, the G4 is a sledgehammer.”

The Revolution III it’s about clarity, punch, & precision. The Revolution IV is more about a thick, saturated distortion. However, when you try them tougher, you can see how good they blend.

Going back to the circuit analysis, one of the most interesting things about is the 3-Band hybrid EQ. Composed by a Baxandall control for bass and treble, plus an active mid control after volume, it makes sure that you can dial this pedal in any way you want it, yet keeping on the definition you need on each frequency.

Both pedals feature an aggression switch that engages different settings of resistors and capacitors to change how the gain on the first stage behaves. Although you must notice that this pedal might squeal on with the aggression switch engage and the gain knob over 75%, we can assure you; you’d have plenty of gain by then.
