Notes & Caveats
- Exact amp knob settings for the studio recording are not published; values are estimated based on typical Mesa/Boogie Studio Preamp settings for Cobain's tone and era.
- Pedal settings for the Boss DS-1 and EHX Small Clone are sourced from forum posts and user analysis, not official studio notes.
- Guitar model is confirmed for the 'Nevermind' sessions, but some sources mention live use of Stratocasters; this JSON is for the studio recording only.
- Presence and reverb settings are estimated based on genre and typical Mesa/Boogie/Marshall stack use in early 90s grunge recordings.
- Settings cross-referenced with genre and era conventions for accuracy. Kurt Cobain's 'In Bloom' riff tone is a saturated, mid-forward grunge crunch with tight low end and pronounced attack, likely from a Mesa/Boogie or similar amp with high gain, moderate bass, even mids, and slightly boosted treble/presence; the recording is dry with no audible reverb, matching the early '90s Seattle sound.
