EHX Big Muff Pi Nano Settings Guide
The EHX Big Muff Pi Nano is the compact version of the classic silicon Big Muff Pi — the same civil-war era circuit with Sustain, Tone, and Volume in a pedalboard-friendly enclosure. The Big Muff Pi circuit, in its silicon incarnation, produces a thick, sustaining, wall-of-sound fuzz/distortion that sits between fuzz and distortion in character. David Gilmour, Smashing Pumpkins, Dinosaur Jr., and many more have made it central to their sound.
Used by: David Gilmour
The best EHX Big Muff Pi Nano settings start with: Volume at 6/10, Tone at 5/10, Sustain at 6/10. Adjust from there based on your amp, guitar, and room volume. For Alternative / Grunge: Volume 6/10, Tone 5/10, Sustain 8/10.

Settings by Genre
High Sustain for wall-of-fuzz alternative rock — the Big Muff at Sustain 8 produces the massive, mid-scooped fuzz that Smashing Pumpkins (Siamese Dream) and Dinosaur Jr. built their sound around. The silicon circuit's mid scoop means it sits in the mix without masking the bass.
Maximum Sustain with Tone slightly dark — shoegaze uses the Big Muff as a droning, sustained fuzz underneath tremolo picking. Tone at 4 prevents the high-end from becoming harsh at extreme Sustain settings. The wall of sustained fuzz is the aesthetic foundation of the genre.
Moderate Sustain with Tone slightly bright — Gilmour's Comfortably Numb solo and Animals-era lead tones used the Big Muff for singing, sustained lead lines. The silicon Big Muff at Sustain 6 has enough saturation for infinite sustain on bends without losing note definition.
Dark Tone with high Sustain — the bass-forward Big Muff character suits slow, droning psychedelic rock. Tone at 3 reduces the high-end harshness and emphasises the low-mid density of the fuzz.
Artist Settings
Documented settings used by professional guitarists on this unit.
Gilmour used various Big Muff Pi versions throughout his career. His typical approach was to use the Muff for extended lead tones where sustain and bloom were the priority. The specific model he used changed across different recordings and tours (ram's head, civil war, various custom versions) but the general setting of moderate Sustain with brighter Tone remained consistent.
Tips & Common Mistakes
- The Big Muff Pi's mid scoop is its defining characteristic — the circuit naturally cuts midrange frequencies, producing a scooped, bass-and-treble-heavy tone. This sounds thin in isolation but powerful in a full band mix. If the Big Muff sounds thin or weak, try it in context with the full band before adjusting.
- The Nano version is the same circuit as the standard Big Muff Pi in a smaller enclosure — no circuit differences. Choose Nano for pedalboard space; standard for the larger footswitch (easier to engage precisely on stage).
