Electro-Harmonix releases Big Muff Pi 2 Dual Op-Amp Fuzz

Electro-Harmonix has announced the release of the Big Muff Pi 2 dual op-amp fuzz pedal, a circuit based on a design by original Big Muff creator Bob Myer that was never previously manufactured. The schematic for this unreleased circuit, labeled 'BIG MUFF USING (2 DUAL OP AMPS),' was uncovered by EHX enthusiasts Josh Scott of JHS Pedals and Daniel Danger while researching the company's history. Scott collaborated with Electro-Harmonix to realize the design. The circuit utilizes two dual op-amps, distinguishing it from both the classic transistor-based Big Muff variants and the previously released Op-Amp Big Muff Pi from the late 1970s. This configuration results in a fuzz tone that is described as having slightly lower gain and a less refined character compared to other Big Muff models. It reportedly offers a pronounced low-end and midrange presence, delivering high output volume and singing sustain. The unit is housed in a compact nano-sized chassis and features the standard three-control layout common to the Big Muff family. Key Features Circuit Type: Analog Dual Op-Amp Fuzz based on a late 1970s schematic by Bob Myer. Controls: Sustain (distortion amount), Tone (variable filter cutting bass and boosting treble when turned clockwise), and Vol (output level). Chassis: Nano-sized die-cast enclosure with graphics designed by Daniel Danger. Bypass: Features silent true bypass switching via a mechanical relay. Footswitch: Offers both standard latching and momentary action. Power: Requires 9VDC (15mA, center-negative plug). Ships with a 9V battery; optional power supply is not included. {PRODUCT-HEADER-33978-bigmuffpi2}.
