Tone Timeline
Brian May — Tone Evolution
May built his own guitar at 16 (the "Red Special") and never needed another. The Vox AC30 / Deacy Amp / phaser combination is among the most distinctive and immediately recognisable signal chains in rock history.
1973–1977: Queen I / News of the World
The early Queen records captured the Red Special through Vox AC30s, with May using sixpences (British coins) as picks for a brighter, more clanky attack. The treble-booster-driven AC30 saturates into a singing, harmonically complex tone. Bohemian Rhapsody's operatic guitar solo used a single Red Special into an AC30.

↑ Deacy Amp introduced — the tiny, warm compressed quality of the home-built amp added depth and character unavailable from any commercial unit.
The later 1970s saw May adding the MXR Phase 90 and experimenting with the Rangemaster replacement booster designs. The Deacy Amp (built by John Deacon from a discarded amp chassis) appeared for studio work — a tiny amp that gave a distinctive compressed, warm quality.

1984–present: Works / Innuendo / Solo
↑ Fryer treble booster replaced the Rangemaster — same concept, improved consistency and more reliable modern component spec.
The Innuendo era saw May modestly expanding the effects chain with Boss pedals and a Fryer treble booster, while keeping the Red Special at the centre. His solo records use the identical approach — sixpence pick, Red Special, treble booster, AC30.
