Electro-Harmonix Deluxe Bass Big Muff Pi 2

Electro-Harmonix Deluxe Bass Big Muff Pi 2 – Maximum fuzz with total control for bass

The Deluxe Bass Big Muff Pi 2 takes the classic, once "lost" Big Muff 2 design with dual op-amps to an entirely new level. With flexible tone shaping and professional upgrades, it delivers a massive fuzz sound tailored for modern bassists who demand both power and control.

The pedal retains the original’s signature midrange bite, combined with the long sustain and dynamic response that made the Big Muff an icon. This Deluxe version adds a BLEND control, noise gate and an advanced CROSSOVER section that offers unique possibilities for precise sound shaping.

The BLEND knob allows you to easily mix clean and distorted signals for aggressive fuzz tones with a clear low-end. The GATE function removes unwanted noise and keeps your playing tight and defined. The footswitchable CROSSOVER function splits the signal into two paths: a high-pass filtered signal sent to the fuzz circuit and a low-pass filtered clean signal. The result is a clear, aggressive fuzz on top combined with massive, clean bass at the bottom.

The pedal is also equipped with an expanded input and output system for both studio and stage use. The XLR DI output makes it easy to connect directly to a mixer or recording equipment, while the DIRECT OUT provides a buffered, completely clean bass signal.

The true bypass footswitch offers both latching and momentary operation: tap once for classic on/off switching, or press and hold the footswitch for a temporary explosion of fuzz.
