Why these settings

The original JCM800 at gain 4.5 is a touch-sensitive edge-of-breakup British crunch. The NUX Mighty 20bt's Crunch channel (British-voiced) approximates this — gain 3 keeps it clean enough for the chorus to shimmer without mud. Mid +6 compensates for the Enya's humbuckers being warmer than Marcovich's Strat single-coil quack. Treble stays conservative at 5 because humbuckers don't need the brightness push a Strat would. The NUX lacks a presence knob — that's normal.

PRO TIPThe magic of this tone is the right-hand muting and syncopation on the montuno figure — palm-mute lightly on the low strings while letting the higher chord tones ring through the chorus. Roll your tone knob to 7 to tame the humbucker's top-end bite and get closer to Marcovich's vocal, singing Strat quality.
