For this pedal we can say that it’s clearly an amazing conversion of the original Revv Generator Tube Amp, where you can see a pretty similar schematic to the ones present here. This is possible using the same principle of Tube-to-Jfet we have seen in many of the modern high gain pedals such as the Friedman Be-OD, or our Wolfgang 5150.
As you can see both pedals look very similar, not only by the controls, but also by the components and the schematic, however they sound pretty different, being definitely complementary of 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. Both can be totally complementary to each other, that’s why this pack includes for free an extra order switch, so you can place them both in the same enclosure as your own portable preamp and play it everywhere!
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, making sure that you can dial this pedal in any way you want it, yet keep on the definition you need on each frequency.
Both pedals features 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%, but we can assure you, you’d have plenty of gain by then.
This board has been designed featuring a special grill for the ground net in order to keep all the unwanted noises as low as possible.
