Why these settings

Your Solar has passive humbuckers vs Hetfield's hot EMG 81s, so gain goes from his effective 8.5 down to 7 to avoid mud — the NUX's digital gain is more saturated than a real Mark IIC+. Mids scooped hard to 2 (original was ~1-3) to replicate the 'Justice' sound. The Cali Crunch model approximates the Mark series voicing; if it lacks punch, switch to Dual Rect and drop gain to 6.

PRO TIPThe 'Justice' tone is ALL about right-hand precision — palm mute directly over the bridge saddles (not toward the neck) for that machine-gun chunk, and pick closer to the bridge with a stiff 1mm+ pick for maximum attack and note definition.
