Why these settings

The Jackson JS22 ceramic bridge humbucker closely matches the hot, bright output of the original DiMarzio Super Distortion. Using the GT-1's Marshall amp block with a slight low-mid dip and upper-mid boost captures the polished Mutt Lange production sound without getting muddy. Keep the amp gain moderate at 6 so chord definition remains crisp during full-voiced chords.

PRO TIPPick hard right near the bridge saddles with a stiff pick to get the signature percussive '80s pop-metal transient on the opening riff.
