Why these settings

The Cube 40GX's CRUNCH channel approximates a British-voiced amp but sits flatter than a real JCM800. I pushed mids to 7 (vs a Marshall's natural 5-6) to compensate for the Cube's more neutral voicing. Your Pacifica's Alnico V bridge humbucker is lower output than a Gibson PAF, so gain stays at 6 rather than dropping it. Rolled tone knob to 7 to tame the Pacifica's slightly brighter top end versus a mahogany Les Paul.

PRO TIPRobe's attack is critical to this tone — use the thick part of the pick angled slightly and dig in hard on downstrokes. Back off your guitar volume to 7-8 for the verse clean-up, then slam it to 10 for the heavy sections; the Cube's CRUNCH channel responds well to this dynamic.
