Why these settings

The Marshall MG50DFX solid-state preamp needs gain at 8 on the Overdrive channel with the Contour control turned clockwise (around 7-8) to replicate the Mesa Mark IIC+ graphic EQ mid-scoop. We scoop the amp's Middle knob down to 2 and elevate Bass and Treble to match the punch and bite of the JCM800 power section. Adding an external graphic EQ pedal in the FX loop will bridge the final gap to Hetfield's extreme V-curve.

PRO TIPStrict downpicking with heavy palm-muting right against the bridge saddles is essential to get the percussive, machine-gun chug attack of this track.
