Why these settings

The solid-state GA-1065 clean channel acts as a pedal platform to avoid harsh double-gain clipping, letting the Boss DS-1 supply the cranked Marshall Plexi saturation. Because your Stratocaster bridge single-coil is brighter and thinner than Eddie's PAF humbucker, keep the DS-1 Tone knob rolled back to 4 and push the amp midrange to 8 for authentic Brown Sound bark. When you add a Phase 90, run it before the DS-1 with the Speed dialed low around 9 o'clock.

PRO TIPLightly strike your pick with the side of your thumb (pinch harmonic attack) on the aggressive riff sections, and rest your index finger parallel across unplayed strings during tapping sequences to keep the high-gain DS-1 quiet.
