Why these settings

The original used a cranked Plexi plus RAT for stacked gain into a bright 4x12. Your Fender Champion 20 has no mid control and a scooped clean platform, so the RAT pedal becomes mandatory—it supplies the Marshall-style mid presence and aggressive gain the amp cannot produce alone. Amp gain stays at 2 to keep the clean headroom; the RAT does all the work. Treble is maxed at 8 to compensate for the Champion's darker 8-inch speaker versus the original's bright Celestions.

PRO TIPPick HARD with downstrokes near the bridge—early Metallica rhythm tone lives in the attack transient, not sustain. Your P90s in the Les Paul Special will sound grittier and slightly darker than Kirk's EMG 81s; this actually works well for the raw Kill 'Em All era vibe.
