Product Description

The EHX Bass Big Muff lets you rip and rumble with a full fuzz tone and no low-end loss. Inspired by the mythical bass response of the Black Russian Big Muffs of the 90’s, the distortion of the Bass Big Muff hits like a ton of bricks, sludgy mortor and all. The classic three-knob design of Volume, Tone, and Sustain make for familiar control over the fuzz circuit. A Dry/Bass Boost switch either mixes you dry signal with the fuzz tone or reintroduces more low frequencies into the fuzz circuit, which is useful when the Tone knob is set high. A seperate Dry output allows for two amps sets for increased setup versatility.


From the manufacturer

Bass Big Muff Pi Distortion/Sustainer

The Prodigy reborn with underworld instincts comes to life wielding the drive of the original classic Big Muff Pi and the earthy support of a bass tailored design with no loss of low end. This is the pedal that bass players who loved the Big Muff sound have been waiting for.

Volume knob

The volume knob sets the output level of the distortion. When the toggle switch is set to DRY, the volume knob has no effect on the output level of your original bass.

Tone knob

Provides a range of sounds from high treble to deep bass. The overall tone filter frequencies were carefully chosen to enhance your bass guitar.

Sustain knob

As in the original Big Muff Pi, adjusts the amount of sustain and distortion.

Bass boost / norm / dry toggle switch

This is a 3 position toggle switch that allows you to choose three distinctly different sounds. In Bass Boost mode, the top position, a bass frequency boost is added to the distortion. It is most effective when the Tone knob is set to the upper or treble half of its rotation. In Norm mode, the middle position, you have the pure tone of the classic Big Muff Pi. In Dry mode, the bottom position, the original dry signal from your instrument is mixed with the output of the distortion circuit. The level of the Dry signal is constant and will not change as you turn the Volume knob up or down. This allows you to set the level of the distortion effect against your dry signal.
