Professor’s Notes

The Nano Bass Big Muff Pi delivers the same low-end preserving fuzz of the classic Bass Big Muff in a more compact, pedalboard-friendly enclosure. It’s the perfect choice for bassists who want iconic Muff sustain and grit without losing punch or clarity.

Description

The Electro-Harmonix Nano Bass Big Muff Pi packs one of EHX’s most popular bass fuzz circuits into a smaller footprint, making it easier than ever to fit onto crowded pedalboards. Designed specifically for bass, it combines the sustain and harmonic richness of the original Big Muff with tailored features to keep bass fundamentals intact.

Controls for Volume, Tone, and Sustain are complemented by a Dry switch, which allows players to blend clean signal with fuzz for extra clarity and presence. The result is a versatile bass fuzz pedal that can deliver subtle growl, thick sustain, or massive walls of fuzz without sacrificing low frequencies.

Compared to vintage Muffs or the larger Bass Big Muff, the Nano version offers the same tone in a rugged, compact housing that’s ideal for gigging or studio use. It’s a true EHX workhorse — affordable, reliable, and unmistakably Muff.
