One amp settings — Fender Champion 20
The Mettalica guitar tone for “One”, dialed in for a Fender Champion 20 with a Cort X300. Studio version, ...And Justice for All (1988) — main rhythm riff tone
ESP MX-220 with EMG 81/60 pickups, Mesa/Boogie Mark IIC+ (slaved into Marshall power section), onboard graphic EQ (classic V-curve), noise gate
| Knob | Setting (0–10) |
|---|---|
| Gain | 8 |
| Bass | 8 |
| Treble | 7 |
| Reverb | 1 |
| Master | 5 |
The Champion 20 lacks a dedicated mid knob, so the classic Mark IIC+ V-curve scoop is achieved by setting the Voice selector to the high-gain Metal voice and boosting bass to 8 and treble to 7. Your Cort X300 active/hot humbuckers provide the fast transient attack needed to emulate Hetfield's active EMGs without muddying the low end. Keep onboard reverb extremely subtle at 1 to match the bone-dry, clinical production of the record. Clean intro: switch Voice selector to Tweed/Blackface clean, neck pickup.
