Zvex M080 Fuzz Factory Special

The ZVEX M080 electric guitar effects pedal is a germanium fuzz pedal used by many guitarists, including Muse's Matthew Bellamy. It's a one-off Special Series.Action of the potentiometers, according to Zachary Vex: "Gate": turn to the right to eliminate hiss or adjust feedback pitch, and to the left to open the gate. "Compress": Adds attack when turned to the left and softens when turned to the right. "Drive": Increases distortion when used as a "normal" fuzz and adjusts the coarseness of the sound (no effect if the Compress knob is turned fully right). "Stability: Use all the way to the right. Don't try to set this knob below 2 o'clock, unless you like your Fuzz soft and squishy. Use to control feedback pitch.
