Why these settings

The DSL40CR's Classic Gain Crunch channel nails the cranked early-80s Plexi/JMP response Randy used on tour when pushed with a front-end overdrive. The Ibanez RG550 V8 bridge pickup has more high-mid clarity and tighter output than Randy's vintage Les Paul humbuckers, so the amp bass is anchored at 5 while the MXR 10-band EQ pushes the essential 1kHz and 2kHz bands to reproduce his cutting solo attack. Your Fat Rat and Pentatone remain bypassed to keep the saturation strictly British and articulate without double-stacking distortion stages.

PRO TIPRandy aggressively used heavy edge-picking near the bridge saddle on his solos; angle your pick 45 degrees toward the headstock to squeeze out his screaming, razor-sharp pinch harmonics on the D and G strings.
