Killer queen amp settings — Rj 15

The Queen guitar tone for “Killer queen”, dialed in for a Rj 15 with a Fender Player Stratocaster. Studio version, Sheer Heart Attack (1974)

Original rig

Brian May Red Special (bridge+middle in series) → Dallas Rangemaster Treble Booster → Vox AC30 (Normal channel, cranked) with room mic ambience

Warm, singing midrange overdrive with chimey harmonics, smooth sustain, and studio room ambience — not aggressive or modern distorted

Simulates the Rangemaster treble booster — keep gain LOW, level HIGH to push amp front-end. The original tone was overdriven, not distorted. If your pedal has a 'boost' mode, use it.

Why these settings

The RJ 15 is a basic solid-state practice amp that lacks the harmonic tube compression of an AC30. Your distortion pedal set to low gain/high level mimics the treble booster pushing a clean amp. Mid boosted +1 vs typical AC30 settings because the RJ 15 has a flatter, less mid-forward voicing. Treble dropped to 5 because your Strat's single coils are brighter than May's series-wired Red Special pickups. Reverb at 3 simulates the studio room ambience heard on the recording.

PRO TIPMay used a sixpence coin as a pick for that distinctive attack and harmonic overtone — try a heavier pick (1mm+) held loosely and strike the strings with a slight angle to approximate that texture. Roll your tone knob to 6-7 during the verse for the mellower rhythm parts, then open to 8-9 for the solo.
