Why these settings

Original Mark IIC+ is tight and mid-scooped with surgical precision. The Mustang's Metal 2000 model approximates this voicing but is looser in the low end—dropped bass from 5.5 to 5 and raised mid from 3.5 to 4 to compensate for the Strat's thinner single-coil output vs Hetfield's hot humbuckers. Reverb set to 0 as the recording is bone dry.

PRO TIPPalm mute directly over the bridge saddles with the heel of your hand barely touching the strings—the Justice-era tone lives in that ultra-tight chug, and loose muting will turn it to mush on a modeling amp.
