The Fuzz Stain is a pedal that is inspired by the Sam Ash Fuzz-Stainer. It features four controls: Volume, Fuzz, Tone, and Bias. The Volume control allows you to adjust the output level of the pedal, while the Fuzz control adjusts the amount of fuzz or distortion applied to your signal. The Tone control lets you shape the overall tonal character of the fuzz, allowing you to dial in a brighter or darker sound. The Bias control is used to adjust the bias voltage of the circuit, which can affect the overall tone and response of the fuzz.
