Why these settings

The intro clean was tracked with an EMG 60 into a crystal-clean solid-state Roland JC-120 with lush chorus. On your solid-state Randall Jx30d, use the Clean channel with low gain to prevent breakup and dial the onboard DSP to a moderate Chorus setting. The Jackson JS22 passive neck humbucker needs a slight mid scoop and boosted treble to emulate the glassy clarity of active EMG cleans.

PRO TIPPick cleanly with a stiff 1.0mm+ plectrum near the middle between the neck and bridge to replicate James Hetfield's crisp, percussive clean arpeggios.
