EH Big muff Op-amp pedal.

This pedal was fully tested and works as it should with no issues. No Box.

The Electro-Harmonix Op-Amp Big Muff Pi is a faithful modern reissue of the classic late-1970s (V4/V5) IC-driven fuzz pedal, famously used by Billy Corgan on the Smashing Pumpkins' Siamese Dream.

Key Features & Specifications

• Circuit Design: Uses operational amplifiers (op-amps) instead of standard transistors and features three gain stages instead of four for a heavier, crunchier, and more abrasive wall-of-sound tone.
• Controls: Standard Volume, Sustain, and Tone knobs.
• Tone Switch: A toggle switch that completely removes the Tone control from the circuit to boost volume and alter the gain structure.
• Modern Enhancements: Housed in a compact, pedalboard-friendly die-cast chassis with true bypass switching and an LED effect-status indicator.
• Power: Powered by a 9V battery or an optional 9V DC center-negative power supply.
