Why these settings

The ME-90B's CRUNCH amp type approximates the hot-rodded JCM800 voicing of Hetfield's modified Marshall. Your GRG170DX's Infinity R humbuckers are hotter and darker than the vintage Flying V pickups, so treble is dropped from 8 to 7 and mids raised slightly from the original's extreme scoop (reported at 2-2.5) to 3 for clarity. Bass pulled back from 7-9 to 6 because the Ibanez's basswood body and tight low-end won't need as much push.

PRO TIPHetfield's right-hand attack on this track is relentless downstrokes with the pick angled slightly—dig in hard near the bridge pickup for that percussive chunk, and keep your palm muting tight but not choking the note's initial attack.
