Signal chain

01Treble Booster (e.g., BSM RM, TC Electronic Spark, or Analogman Beano Boost)

RECOMMENDED — not currently owned. This pedal is essential to May's tone; it pushes upper mids into the amp's front end, creating the singing sustain. Without it, the tone will lack the harmonic complexity and vocal quality.

Boost/Level 6

Why these settings

The Hot Rod Deluxe is brighter and more scooped than the AC30 Normal channel, so treble drops from 6 to 5 and mids rise from 6 to 7 to compensate. Your Les Paul's humbuckers are hotter and darker than the Red Special's Burns Tri-Sonics wired in series, so gain drops to 4 (original was cranked amp breakup) and tone knob stays at 7 to retain clarity. Push master volume to 6 to engage tube compression — this amp needs volume for the smooth sustain May achieved.

PRO TIPRoll your guitar volume to 8 instead of 10 to clean up the attack slightly and mimic the Red Special's phase-combined output — this lets individual notes 'bloom' rather than hit hard, which is central to the bell-like solo sound on this track.
