Why these settings

The Jackson JS22 Monarkh carries passive high-output humbuckers rather than James Hetfield's active EMG 81s, so the onboard TS drive block is engaged as a clean boost to recreate that tight attack. The Mooer GE100's Cali MK model reproduces the Mesa Mark preamp, with mids pulled down to 3 and treble boosted to replicate the famous post-distortion graphic EQ V-curve. For the clean interlude: switch to the 65 TWIN clean model, turn off the drive block, and switch the Jackson to the neck pickup.

PRO TIPEvery single rhythm note in the main riff must be strictly downpicked with heavy palm-muting right against the bridge saddles to get the signature percussive thump.
