Notes & Caveats
- No direct numeric amp settings for 'All Apologies' found; amp EQ estimated based on Cobain's quote about 'all the midrange up' and typical Mesa/Marshall settings for 90s grunge.
- SansAmp DIP switch and knob settings referenced from general In Utero session info, not song-specific.
- No evidence of chorus, delay, or modulation effects in the riff section; chorus pedal was used on other songs but not audibly present here.
- Guitar model inferred from studio session notes and typical use; some sources mention Jaguar/Strat, but Mustang with bridge humbucker is most likely for this part.
- Presence and reverb settings estimated based on typical studio tones and lack of audible ambience.
- Settings cross-referenced with genre and era conventions for accuracy. Kurt Cobain's 'All Apologies' riff tone is crunchy but not high gain, with a balanced, mid-forward EQ typical of his Jaguar/Mustang through a clean-ish Fender amp and DS-1/DS-2 pedal. The mix is warm, not overly bright, with subtle room reverb and no scooped mids, reflecting early '90s grunge production.
