This project is a Fuzz Face inspired circuit with two unique features. The first is a knob for Bias control, which regulates the voltage fed into the second transistor. The second is a big muff tone stack just before the output, allowing the user to shape the tone. The circuit starts with two gain stages running into each other, with an input gain control and a sag on the second stage. The sound is dependent on the transistors used; the original version uses a couple of 2N1711 NPN silicon, but replacing them can create a different sound. The controls for this project are Volume, Bias, Dirt, and Tone. The Volume control adjusts the overall output level, while the Bias control adjusts the voltage fed into the second transistor. The Dirt control adjusts the amount of gain, and the Tone control adjusts the frequency response of the output. Overall, this project is a unique take on the classic Fuzz Face circuit, with two features that allow the user to customize the sound. With the Bias control and Tone stack, users can create a wide range of sounds, from classic fuzz to something entirely new.
