Why these settings

The JCM900 Lead channel supplies ample diode-clipping bite to match Synyster Gates' aggressive pick attack, but running a single-coil bridge Strat requires pushing the bass to 6 and rolling guitar tone back to 8 to tame single-coil sharpness. Keep mids around 5 so the fast 16th-note gallops retain cut without getting overly thin or flubby. If you later acquire the recommended TS9/SD-1, run it as a clean boost (Drive 1, Level 9) into Channel B and drop the amp gain to 6 for maximum low-end tightness.

PRO TIPUse heavy, precise palm-muting right against the bridge saddles on the open Drop D chugs to keep the riff percussive and separated from the unmuted melodic pull-offs.
