Why these settings

The Snakebyte's active EMG Het Set provides high-output bite, so gain is kept at 7 to prevent fizzy saturation. On the Marshall Code 50, select the 'American High Gain' preamp model with the 1960V cab, pull the mid knob down hard to 2 to replicate the iconic Mark IIC+ graphic EQ scoop, and set reverb strictly to 0 for the bone-dry Justice production sound.

PRO TIPLock your palm directly against the bridge saddles and execute strict, relentless downpicking on all rhythm figures to get Hetfield's signature percussive thud.
