Roland documents the JC-120 as Hetfield's long-running clean amp and explicitly links it to Welcome Home (Sanitarium). The heavier Master of Puppets album tones are widely tied to Mesa/Boogie Mark IIC+ heads, but this row focuses on the clean intro texture.

No Sanitarium clean-intro knob sheet was located. Settings are estimated from Hetfield's documented JC-120 clean usage and the song's bright, glassy, high-headroom intro tone.

1.Roland JC-120 built-in chorus — Estimated from the JC-120's signature role in Hetfield's clean sounds and the subtle width heard on the intro.

2.Studio reverb — Used as a conservative estimate to add ambience without softening the picking detail.

Playing Technique

Play the clean arpeggios with very even dynamics and strict muting between note groups. Let the notes ring just long enough to create the haunting sustain, but keep the right hand controlled so the tone stays glassy rather than gritty.
