Dirt Device

Inspired by EQD Dirt Transmitter

Project overview
Clearly 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.
Introduction
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 have the voltage feedback added, and it became similar to a fuzz face in topology, but it sounds nothing like one!. In this case, the sound is totally dependent on the transistors; the original version works with a couple of 2N1711 NPN silicon, replace them and it’s a whole different beast.

The EQD Transmitter is like the love of my life, and we’re back together again. It has a very particular sound that I couldn’t live without and this clone nailed it; it is a different type of fuzz that can get REALLY loud and stay very quiet. Sounds great in front of my Fender Twin Reverb
