Notes & Caveats
- No direct numeric amp settings found for the clean riff section; settings estimated based on typical Fender Twin Reverb use in 1990s alternative rock.
- No evidence of pedals or additional effects used for the clean riff; chorus, delay, and modulation are not audible in the recording.
- Pickup choice inferred from Cobain's known preference for bridge pickup on clean parts and forum discussion.
- Some sources discuss general Nirvana gear or live rigs, but this is focused on the studio recording for 'In Utero' (1993).
- Settings cross-referenced with genre and era conventions for accuracy. Kurt Cobain used a crunchy, mid-forward tone with moderate gain, typical of his early-90s grunge sound, likely from a cranked clean or slightly overdriven amp (like a Fender Twin or Mesa/Marshall), with little to no reverb. The tone is thick, not scooped, and avoids excessive brightness or low-end boom.
