Why these settings

The Mustang LT25's Metal 2000 model approximates the Rectifier's saturated modern voice. Your Epiphone's Probucker humbuckers are passive and warmer than Daron's active-style pickups, so gain is pushed to 8 (vs 7 on a real Rectifier) and treble stays at 6 to retain pick attack. Mids scooped to 4 replicates the Rectifier's characteristic mid-cut. No physical pedals needed — the built-in noise gate handles the tight stops.

PRO TIPTune to Drop D. The song's percussive attack comes from aggressive downstroke palm-muting right at the bridge saddle — mute hard and pick closer to the bridge than usual for that machine-gun tightness on the verse riff.
