Why these settings

The Spider IV 'Metal Red' model emulates a Dual Rectifier, which naturally has loose low-end and fizz if pushed too hard. Keeping amp gain at 6 and hitting it with the SD-1 (Level high, Drive nearly off) tightens the fast gallops without getting muddy. Your Kramer's bridge humbucker supplies the necessary bite, so the treble is pushed slightly to 7 to preserve articulate pick attack.

PRO TIPAnchor your palm directly across the bridge saddles for the opening riff to choke the chugs hard, keeping the gallops separated and percussive rather than sustained.
