The Big Muff Fuzz Legend, Adapted for Bassists

The Electro-Harmonix Bass Big Muff Pi 2 combines the legacy of the iconic Big Muff with a reimagined version of the 1970s op-amp fuzz circuit, specifically optimized for electric bass.

Developed in collaboration with Josh Scott of JHS Pedals, this pedal recreates the original circuit while adding modern features tailored for bassists seeking a powerful fuzz without sacrificing low-end depth.

The result: a unique, rich, and massive sound capable of electrifying stages and studios alike.

A Fuzz Optimized to Preserve Low-Frequency Sound

The Bass Big Muff Pi 2 retains the signature Big Muff sound:

✔ Thick Saturation

✔ Near-Infinite Sustain

✔ Characteristic Midrange Grain

✔ Flexible EQ

But it also adds bassist-specific controls for enhanced tonal balance.

Advanced Controls and Features

BLEND (Wet/Dry Mix)

Allows you to blend the clean (dry) signal with the fuzz (wet) signal.

Ideal for:

Maintaining the definition of your playing

Keeping the fundamental bass frequencies intact

Preventing a loss of clarity in the mix

BASS BOOST Switch

Activates a low-frequency boost for added depth and impact.

Particularly effective:

With the TONE knob set to higher frequencies

For a massive sound on stage

Classic Big Muff controls

VOL – Output volume

TONE – Equalization (frequency control)

SUSTAIN – Distortion intensity and sustain duration

Versatile footswitch – Latching and momentary modes

The Bass Big Muff Pi 2 features a latching/momentary footswitch:

✔ Standard press = normal operation (latching)

✔ Footswitch hold = momentary burst of intense fuzz

A perfect system for adding dynamic bursts of saturation to your performances.

The circuit uses a true bypass mechanical relay to preserve signal transparency when the pedal is off.
