We’ve re-engineered Catalinbread’s classic design with critical upgrades for the modern player:

Dirt Device DIY overdrive pedal kit The original schematic comes fromClearly a Fuzz Face inspired circuit, but with two interesting features that totally change the nature of this pedal, a knob for Bias control that regulates how much voltage is fed into the second transistor, and a big muff tone stack just before the output that allows you to shape the tone according to your taste. The circuit starts as two gain stages running into each other with an input gain control and a sag on the second stage (bias). Then you
