Electro-Harmonix Bass Big Muff Pi

Electro-Harmonix Bass Big Muff Pi – Classic Fuzz, Tailored for Bass

The Electro-Harmonix Bass Big Muff Pi takes the legendary Big Muff fuzz circuit and tailors it specifically for bass players, delivering deep, saturated distortion without sacrificing your low-end punch. Inspired by the classic Green Russian and NYC Big Muff designs, this pedal gives bassists that thick, harmonically rich fuzz that sits perfectly in a mix.

The 3-way toggle switch lets you choose between **Normal**, **Bass Boost**, and **Dry Blend** modes—giving you control over how much low end is retained or how much clean signal is mixed in. The result is a fuzz that growls without getting lost or muddy, ideal for modern rock, metal, or doom-inspired tones.

With true bypass switching, dedicated Dry and Effect outputs, and a rugged die-cast chassis, the Bass Big Muff is a versatile fuzz built to take a beating on stage or in the studio.
