Artist Settings
Documented settings used by professional guitarists on this unit.
Gilmour used Civil War and Sovtek versions. Moderate sustain, balanced tone — the Big Muff provides singing lead sustain rather than brute-force distortion.
Cobain used an op-amp Big Muff (NYC version) for Smells Like Teen Spirit. High sustain, slightly dark tone, into a clean-to-cranked amp. The specific "ugly" compression was intentional.
Corgan ran the Big Muff very hot (Volume above unity) to compensate for the mid-cut. Maximum sustain for the wall-of-fuzz Siamese Dream lead tones. Into a Mesa Boogie.
Tips & Common Mistakes
- The Big Muff cuts mids heavily — in a band context, set it solo (not with the band playing) and you'll get lost in the mix. Add a mid-boost after it.
- Tone at 9 o'clock (leftward of centre) gives the classic scooped character. Tone at noon is more balanced.
- The Volume knob often needs to go above noon to compensate for the mid-cut volume drop.
- The Big Muff responds well to being driven by a Tube Screamer in front — the TS restores some of the scooped mids.
