Why these settings

The Zoom G1Xon provides the entire high-gain Marshall Super Lead Brown Sound alongside the Phase 90, tape delay, and plate reverb blocks. Because the multi-FX unit acts as the primary gain and amp simulation engine, the Peavey Rage 158 is set to its Clean channel with Pre Gain at 2 to avoid muddy double-amplification. The amp EQ is set neutral with a slight mid push to support the G1Xon's Marshall voicing through the 8-inch speaker.

PRO TIPEddie placed his MXR Phase 90 before the cranked Marshall so the phase sweep accentuates upper-harmonic feedback and pinch harmonics; keep the speed slow so it swells underneath the fast tapping runs.
