Why these settings

The original clean rhythm relies on a British-voiced Selmer amp at edge-of-breakup, captured here via the Clean Warm voice with Blackstar's ISF dialed clockwise. Because your PRS Custom 24 humbuckers produce strong output, gain is dialed to 6 to retain clean headroom without getting muddy, while mids are pushed to 7 to deliver the defining riff punch. Rolling your guitar tone back to 7 smooths out the top-end sizzle of the PRS bridge pickup.

PRO TIPPick firmly right near the bridge with a stiff pick while keeping the guitar tone knob slightly rolled off—the percussive snap combined with the ultra-short DD-8 delay creates the signature synth-like track texture.
