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

The Electro Harmonix Deluxe Big Muff Pi 2 is a dual op-amp fuzz pedal that reimagines the classic Big Muff circuit with expanded tonal control. This deluxe edition pairs two parallel signal paths, each with its own op-amp based distortion stage, allowing players to blend clean and distorted signals or stack two different fuzz textures simultaneously. The topology delivers everything from vintage sustain to modern high-gain saturation, anchored by independent EQ and gain controls that shape each channel with surgical precision. Each op-amp channel features dedicated Bass, Treble, Sustain and Volume controls, giving players granular command over harmonic content and drive characteristics. The pedal includes a Dry/Wet blend control that preserves low-end definition by mixing unaffected signal back into the output, addressing the frequency scooping that traditional Big Muff circuits exhibit. True bypass switching maintains signal integrity when disengaged. The all-analogue signal path runs on standard 9V power, housed in a robust die-cast enclosure with top-mounted jacks for pedalboard efficiency.
