Studio recording, 1974. The riff section was tracked with the Red Special into a Vox AC30, using a Dallas Rangemaster-style treble booster and a sixpence coin as a pick. No evidence of the Deacy amp on the main riff. Effects are from pedals, not amp. No evidence of amp reverb or delay used on the riff section.

Notes & Caveats

  • ⚠️Amp settings (gain 6, bass 6, mid 8, treble 10) are from forum consensus and typical for cranked Vox AC30 with treble booster; no official studio documentation found.
  • ⚠️No evidence of amp reverb or delay on the riff section; delay is used in solos, not the main riff.
  • ⚠️Phaser is sometimes mentioned for Brian May's tone, but not clearly audible or cited for the main riff section of 'Killer Queen'.
  • ⚠️Presence setting estimated based on typical AC30 Top Boost voicing.
  • ⚠️Guitar knob settings inferred from Brian May's typical use (volume/tone high for clarity and dynamics).
  • ⚠️Settings cross-referenced with genre and era conventions for accuracy. Brian May's 'Killer Queen' tone is bright, articulate, and mid-forward with a Vox AC30 at edge-of-breakup, Treble Booster, and minimal reverb. The settings reflect the British rock midrange, May's preference for clarity and cut, and the production's subtle ambience.
