Why these settings

The vintage-voiced Princeton Reverb is a pristine clean tube platform with only Volume, Treble, Bass, and Reverb knobs, making Metallica's cascading Mesa Mark IIC+ thrash saturation physically impossible to achieve from the amp alone. Crank the Princeton's Volume to edge-of-breakup while rolling bass back to 4 to prevent the 10-inch open-back speaker from flubbing out on rapid palm-mutes, and roll your Strat bridge tone down to 8 to tame single-coil icepick bite. Adding a dedicated high-gain distortion or preamp pedal in front is essential to deliver the required scooped saturation and tight compression. Clean interlude: switch to neck pickup and roll guitar volume back to 7.

PRO TIPStrict, aggressive downpicking with heavy palm muting right against the bridge saddles is essential to get the percussive, mechanical chug of Hetfield's rhythm tracks.
