Electro-Harmonix
Description

The Electro-Harmonix Bass Big Muff Pi 2 fuzz pedal carries forward the legacy of the legendary 1970s Big Muff circuit, reworked specifically for bass players who refuse to sacrifice low-end authority. Built in the USA, this pedal uses two dual op-amps to produce aggressive midrange grind and long, singing sustain while preserving the foundational lows bassists depend on. With an added Blend control and dedicated Bass Boost switch, it lets you shape fuzz that hits hard without hollowing out your core tone. Whether you’re after subtle grit or full-on saturation, the EHX Bass Big Muff Pi 2 keeps your bottom end firmly intact.

Dual Op-Amp Circuit With Signature Big Muff Grind

The Bass Big Muff Pi 2 is powered by a distinctive Big Muff design that employs two dual op-amps to deliver sharp attack, focused mids and extended sustain. This circuit captures the raw edge of the vintage op-amp era while maintaining strong clarity and note definition. The result is thick, textured distortion that stays articulate even in dense mixes.

Blend and Bass Boost Controls for Low-End Authority

The Blend knob lets you mix your dry signal with the fuzz to preserve articulation and punch while layering in distortion. Engage the Bass Boost switch to reinforce low frequencies, especially when using brighter Tone settings. Combined with Volume, Tone and Sustain controls, these features give bass players precise control over how much fuzz they add without sacrificing clarity or impact.

True Bypass With Latching and Momentary Switching

A mechanical relay true bypass keeps your clean signal untouched when the pedal is disengaged. The footswitch supports both latching and momentary operation—click for standard on/off control or press and hold for a burst of fuzz on demand. Compact and powered by an included 9V battery or optional adapter, the Electro-Harmonix Bass Big Muff Pi 2 is ready for reliable performance on stage or in the studio.
