Why these settings

To compensate for the Player Strat's single-coil bridge pickup versus Randy's hot DiMarzio humbucker, amp mids are boosted to 8 and the guitar tone knob is rolled back slightly to tame excess glassiness. The NUX MG-300's Plexi model paired with the onboard Distortion+ block reproduces the exact cranked Marshall front-end saturation of the original tracks. The tight low-end cut prevents the Strat's lower output from flubbing out during rapid alternate picking runs.

PRO TIPRandy aggressively double-tracked his solos with heavy pick attack near the bridge; roll your Strat's tone knob down to around 8 to fatten the single-coil while digging hard with a heavy pick to get that iconic biting chirp.
