Why these settings

The Marshall MG30CFX lacks the tube power-amp sag of Eddie's Variac'd Super Lead, so we run the OD1 channel with solid gain while using the Joyo Ultimate Drive with low gain and high level to tighten the front-end attack. The MG30CFX has no physical presence knob, so upper harmonics are pushed by setting treble to 7 and mids to 8. Reverb is set moderately on the built-in plate/spring setting to replicate the Sunset Sound studio echo chamber.

PRO TIPLightly graze the edge of your picking thumb against the string simultaneously with the pick stroke on lower-string riffs to induce Eddie's aggressive natural pinch harmonics.
