The PigButt is a modified version of the Op-Amp Muff pedal. It offers a saturated distortion that is neither too harsh nor too smooth, creating a unique “wall of fuzz” effect. The pedal features a tone bypass switch that provides a mid-range alternative to the traditional Big Muff tone control.

The controls on the PigButt include:

1. VOL: This controls the output volume of the pedal.

2. TONE: Similar to the tone stack found on the Big Muff, but with different values. It allows you to shape the overall tone of the distortion.

3. SUS: This knob adjusts the total amount of distortion produced by the pedal. Turning it up will increase the saturation and intensity of the fuzz.

4. TONE.BYP: When the switch is in the UP position, the tone control is bypassed. This provides a different tonal option, allowing for a mid-range focused sound.

Overall, the PigButt offers a unique take on the Op-Amp Muff pedal, delivering a saturated and textured distortion. With its tone bypass switch and different tone control values, it provides versatility in shaping your desired fuzz sound.
