Electro-Harmonix Bass Big Muff Pi 2 – Classic Op-Amp Fuzz with Low-End Power
Bring iconic Big Muff fuzz to your bass rig without sacrificing the low-end foundation that drives your sound. The Electro-Harmonix Bass Big Muff Pi 2 combines the distinctive midrange grind of the original 1970s Op-Amp Big Muff circuit with bass-focused controls designed to preserve clarity, weight, and impact. Developed for bass players who want aggressive fuzz with plenty of tonal flexibility, it delivers virtually endless sustain and a powerful distortion voice all its own.
Vintage Op-Amp Fuzz, Tuned for Bass
The Bass Big Muff Pi 2 builds on the revived Op-Amp Big Muff design, using a unique circuit featuring two dual op-amps. Its signature midrange character, flexible EQ, and sustaining fuzz provide a distinctive alternative to traditional bass distortion. Added low-frequency control helps keep your sound full and present, even when dialing in more aggressive fuzz tones.
Blend Fuzz and Clean Signal
The BLEND control lets you mix your dry bass signal with the fuzz effect, giving you control over how much distortion sits alongside your original tone. Retain the clarity and foundational low end of your clean signal while adding as much fuzz character as the performance calls for.
Shape Your Tone and Boost the Low End
VOL, SUSTAIN, and TONE controls provide familiar Big Muff sound shaping, while the dedicated BASS BOOST switch adds more overall low end to your signal. This is especially useful when running the TONE control at brighter, more treble-focused settings, helping maintain the weight and impact expected from a bass fuzz pedal.
- VOL: Adjusts the overall output level.
- SUSTAIN: Controls the amount of fuzz and sustain.
- TONE: Shapes the pedal's tonal character.
- BLEND: Mixes the dry and fuzz signals.

Flexible True Bypass Footswitch
The Bass Big Muff Pi 2 features mechanical relay true bypass with a soft-action footswitch that supports both latching and momentary operation. Click the switch for standard latching functionality, or press and hold for a momentary burst of fuzz. It's a flexible performance feature for adding dramatic fuzz accents exactly when you want them.
