Why these settings

The Boss MT-2 acts as the entire preamp and provides the iconic Mesa Mark IIC+ 'V-curve' graphic EQ scoop, so the Marshall MG30FX is set flat on the Clean channel at low gain to avoid muddy double-distortion. The MT-2 Mid knob is pulled back to 3 with Mid Freq set around 800Hz (knob at 4) to replicate the tight thrash scoop without losing pick attack. For the clean interlude, bypass the MT-2 and switch to the neck pickup.

PRO TIPAnchor your palm firmly against the bridge saddles and execute strict downpicking for every chug to get James Hetfield's percussive, machine-gun articulation.
