Electro-Harmonix Big Muff Pi 2 Dual Op-Amp Fuzz Pedal - Red

Unearthed from the archives of Electro-Harmonix co-founder Bob Myer, the Big Muff Pi 2 dual op-amp fuzz brings a forgotten circuit to life with modern precision and vintage attitude. Originally conceived in the late 1970s but never released, this unique dual-op-amp design has been resurrected by EHX disciples Josh Scott (JHS Pedals) and Daniel Danger, transforming a hand-drawn schematic into a pedalboard-ready powerhouse. With singing sustain, rich harmonics and a raw, slightly more dynamic response than the classic Big Muff, the BMP2 delivers a fuzz voice that’s instantly recognizable yet distinctly its own. And in a first for the Big Muff lineage, it also features silent true bypass switching with selectable latching or momentary operation, allowing you to tap into instant bursts of fuzz fury. This instant classic comes wrapped in a nano-sized die-cast chassis with exclusive artwork by Daniel Danger, making it a compact yet powerful addition to any rig.

Classic Big Muff Character With a Fresh Edge

The Big Muff Pi 2 maintains the legendary fuzz personality EHX players know and love, with a few modern twists. Crisp highs cut through dense mixes while full, booming lows provide weight and depth, and its slightly less-refined clipping adds character and bite. The dual-op-amp circuit expands dynamic response, making the BMP2 feel more expressive across picking nuances and note articulation. Whether you’re stacking it with other drives or running it solo, this pedal produces rich sustain and harmonically complex fuzz tones that feel alive and touch-sensitive from chord work to searing lead lines.

Intuitive Controls and Innovative Footswitch Functionality

Shaping the fuzz is simple and immediate with the familiar Big Muff control layout: Sustain delivers everything from gritty medium fuzz to full-on distortion, Tone sculpts treble and bass balance and Volume sets overall output. A first for a Big Muff, the footswitch offers latching or momentary operation, letting you engage standard fuzz or unleash a controlled burst of mayhem with a press-and-hold gesture. True bypass ensures that your clean signal remains pristine when the pedal is disengaged, giving you maximum tonal integrity for stage or studio use.

A Compact, Hand-Assembled Design Built for Modern Rigs

The Big Muff Pi 2 comes in a nano-sized, pedalboard-friendly die-cast enclosure designed for both durability and style. Its eye-catching Daniel Danger artwork makes it as visually striking as it is sonically versatile. The pedal runs on a standard 9V battery or optional adapter, making it quick to integrate into any setup. Hand-assembled with high-quality components and featuring EHX’s renowned attention to detail, the Big Muff Pi 2 is a collector’s gem, a pedalboard essential and a powerful fuzz tool for players seeking classic inspiration with a fresh, expressive edge.
