Why we think this is right
May's chain is one of the best-documented in the instrument's history and the curated prior calls it a confirmed studio chain at confidence 90: Red Special into a treble booster into a cranked Vox AC30 Top Boost. I accepted all three claims. One point of precision rather than disagreement: the curated prior names the booster as a Dallas Rangemaster, and while the Rangemaster (a mid-1960s unit, so entirely era-correct for 1976) is the design May started from and is the standard shorthand, by the mid-1970s the unit on his board was most likely a custom booster built to the same idea. I have kept the curated name and recorded the nuance here rather than substituting an undocumented builder. The booster is on for every note of the song — with May the booster is not an effect that gets switched, it is how the AC30 is driven — and the amplifier never changes channel or setting, so the riff, the verses and the solo are one amplifier voice played with different attack and guitar volume. RULED OUT for this track: no wah, no fuzz box, no phaser, no rotary speaker and no Deacy amp orchestration part — the harmonised guitar lines here are ordinary multitracking of the same rig, and none of those devices is documented or audible on this song. Nothing in the chain postdates 1976.
