One amp settings — Marshall Mini Jubilee
The Metallica guitar tone for “One”, dialed in for a Marshall Mini Jubilee with a Ibanez RGA42FM. Studio version, ...And Justice for All (1988) — heavy distorted sections
Mesa/Boogie Mark IIC+ head, ESP MX-220 with EMG 81 bridge pickup, Ibanez Tube Screamer as boost/tightener

01Distortion (as boost/tightener)
Run into amp input. Low gain, high level — use as a clean boost to tighten the amp's low end, not as a gain source. Mimics the Tube Screamer function on the original recording.
02Delay
Off for main riff sections. The studio recording is bone dry.
03Reverb
Off. ...And Justice for All is notoriously dry — no audible reverb on rhythm guitars.
04Chorus
Off for distorted sections. Only used on clean intro.
The Mini Jubilee is mid-forward like all Marshalls, while the original Mark IIC+ has a deeper mid-scoop and tighter low end. I dropped mids to 3 (vs typical Jubilee settings of 5-6) to approximate the scooped AJFA sound. Your RGA42FM's passive humbuckers are warmer and lower output than Hetfield's active EMGs, so I kept gain at 7 rather than backing off — the distortion pedal set as a low-gain boost will tighten the low end and add the pick attack clarity that EMGs provide naturally.
