Gibbons' first-person Prime Cuts account identifies a digital delay for the Bo Diddley-style tail and a Maestro Ring Modulator for the three verse tags, with the guitar feeding a Marshall Major. His later Guitar Player interview independently confirms the unusual fuzzy lead sound and explains that the source fault was never identified, so no extra fuzz pedal is inserted here. The sources do not publish a jack-to-jack order and the two processors serve different passages; the display groups them as switched studio inserts in conventional delay-then-ring-mod order rather than claiming they were simultaneously connected in series.
No source publishes this sequence. The units are ordered by conventional signal-chain practice, and any documented routing zone is kept as recorded.
