Why these settings

The Princeton Reverb lacks a dedicated midrange control, but its natural tube voice provides a classic scooped profile that suits the 1988 JC-120 clean tone well. Keep the volume around 3 to maintain pure clean headroom without edge-of-breakup saturation from your active EMG pickups. The treble is pushed to 7 to capture the glass-like top end of the original studio track.

PRO TIPSelect the EMG 60 in the neck position and pick strictly with downward angle attacks close to the middle of the body for that signature sharp, hi-fi percussive snap on the intro arpeggios.
