Notes & Caveats

  • ⚠️No direct numeric amp settings found for studio recording; values estimated based on typical Brian May/Queen studio rig for 1975 and AC30/treble booster setup.
  • ⚠️Pickup selection inferred from interviews and technical breakdowns; May used multiple combinations, but bridge+middle in phase is most likely for the heavy riff.
  • ⚠️No evidence of modulation, delay, or wah in the riff section; effects like chorus/flanger/delay are not present in the riff, only treble booster.
  • ⚠️Presence and reverb settings estimated; AC30 has no dedicated presence control, value inferred from typical tone.
  • ⚠️If more specific studio notes surface, settings may need revision.
  • ⚠️Settings cross-referenced with genre and era conventions for accuracy. Brian May's 'Bohemian Rhapsody' riff tone is classic British rock: edge-of-breakup to light crunch, with his Vox AC30 set for strong mids, moderate bass, and clear but not harsh treble. Presence is slightly above neutral for air, and reverb is subtle, as most ambience was added in the mix or room.
