Notes

Studio recording, Bleach album sessions (1988-1989). For 'Mr. Moustache' and most Bleach tracks, Cobain used his red Epiphone ET-270 into a Randall solid-state head and BFI Bullfrog 4x12 cab, with a Boss DS-1 for distortion. This is confirmed by multiple sources including Guitar World and Live Nirvana. No evidence of modulation or time-based effects on this track. Settings estimated based on genre, amp type, and era.

Difficulty

The riff is fast and requires tight palm muting and aggressive picking, but uses straightforward power chords and rhythm, making it accessible to intermediate players.
