Notes & Caveats

  • ⚠️No direct photo or interview with exact amp knob settings for 'Heart-Shaped Box' studio recording; settings estimated based on genre, era, and typical Cobain approach.
  • ⚠️Some sources mention Vox AC30 and Mesa/Boogie for 'Nevermind' but not for 'In Utero'/'Heart-Shaped Box'.
  • ⚠️No evidence of modulation, delay, or reverb pedals in the riff section; only Boss DS-2 Turbo Distortion is confirmed.
  • ⚠️Pickup selection inferred from typical Cobain usage and tonal characteristics; bridge pickup is most likely for main riff.
  • ⚠️Amp reverb is set low; no evidence of heavy reverb in the riff.
  • ⚠️Settings cross-referenced with genre and era conventions for accuracy. Kurt Cobain's 'Heart-Shaped Box' riff tone is a mid-forward, crunchy sound typical of his early 90s Jaguar/Mustang through a cranked clean-ish amp (often a Fender or Mesa/Marshall) with a DS-1/DS-2 pedal. The amp is set for moderate gain and warmth, with mids slightly boosted, treble and presence moderate, and reverb nearly off to keep the tone dry and direct as on the In Utero recording.
