Electro-Harmonix Big Muff Pi 2 Fuzz Pedal - Dual Op-Amp, Nano | No Limit Guitar Co, Idaho Falls

The Electro-Harmonix Big Muff Pi 2 is a resurrection of a lost circuit — a previously unreleased dual op-amp fuzz design from the late 1970s, unearthed from the personal files of EHX co-designer Bob Myer and brought back to life by Josh Scott of JHS Pedals. Built for guitar players who know and love the Big Muff legacy, the BMP2 delivers the same singing sustain and singing, sustained grind of the original with its own distinct edge: gnarlier clipping, more dynamic response, and a woolier, more raw fuzz texture that's unmistakably Muff. At No Limit Guitar Co in Idaho Falls, this is one of the most compelling new fuzz pedals to hit shelves in years.

Product Overview

The story behind the Big Muff Pi 2 is as compelling as the circuit itself. EHX founder Mike Matthews and serial inventor Bob Myer created the original Big Muff together, and over the decades Bob continued to bring new designs to Mike as technology evolved. The dual op-amp circuit that became the BMP2 was one that didn't make the cut in the late 1970s — shelved and forgotten in Bob's workshop files for decades. During an interview at Bob's old workshop, EHX devotees Josh Scott of JHS Pedals and artist Daniel Danger discovered the hand-drawn schematic among Bob's notes. Josh decoded and optimized the circuit, resurrecting it as the Big Muff Pi 2 for a new generation of fuzz players.

Sonically, the BMP2 sits in familiar Big Muff territory while staking out its own identity. A crispy top end, booming lows, and less-refined clipping give it a texture that's more dynamic and woolier than earlier iterations — stopping just short of zipper territory and landing in a zone that's simultaneously raw and musical. The Sustain knob sweeps from medium-grit crunch to full-blown wall-of-fuzz saturation, while the Tone control ranges from deep, resonant thunder to brash, ear-splitting rasp as it's turned up.

The Big Muff Pi 2 introduces a first for the Big Muff line: silent true bypass switching with both latching and momentary footswitch action. Click for standard on/off operation, or press and hold for a momentary burst of fuzz mayhem that releases the moment you lift your foot — a performance tool with no precedent in the Muff catalog. The nano-sized die-cast chassis keeps the pedalboard footprint minimal, and the distinctive artwork by EHX aficionado Daniel Danger makes it one of the most visually striking pedals in the Idaho Falls guitar shop.

Key Features

Resurrected Dual Op-Amp Circuit The BMP2's circuit was designed by Bob Myer in the late 1970s, never released, and rediscovered decades later by Josh Scott of JHS Pedals — who decoded the original hand-drawn schematic and optimized it for production. The result is a fuzz tone that's distinct from any previous Big Muff iteration.

More Dynamic, Woolier Fuzz Character Less-refined clipping gives the Big Muff Pi 2 a gnarlier, more tactile response than earlier models, with a crispy top end, booming low end, and a slightly more dynamic feel that rewards expressive playing.

Volume, Tone & Sustain Controls The familiar three-knob layout keeps the BMP2 intuitive for any Big Muff veteran. Sustain sweeps from medium grit to full fuzz fury; Tone moves from deep thunder to brash treble rasp; Volume sets overall output level.

Latching & Momentary Footswitch A first for the Big Muff line — the footswitch operates in both standard latching mode and momentary mode (active only while held), opening up real-time performance techniques not possible with previous Muff pedals.

Nano Chassis with Daniel Danger Artwork The compact die-cast nano chassis keeps the pedal small enough for even the most crowded pedalboard, while original artwork by EHX aficionado Daniel Danger makes it one of the most visually distinctive fuzz pedals available.
