EHX is known for its wide variety of effects, not only for guitar but also for basses. The Big Muff Pi provides the nice fuzzy sound most of us know and love from guitarists, but combines it with the option to boost your bass-sound without losing sound quality.
It has 3 knobs which provide a simple but effective way to shape the sound and a 3-way-switch below offers the pure fuzz sound, the fuzz sound with a bass boost or the raw bass sound.
The stomper is made of solid metal and can be powered either by a battery 9v-block or a power supply.
Overall the Big Muff Pi provides a variety of sounds but keeps your basses where they are supposed to be. Low and heavy
