Why these settings

Your SV20H is a Plexi-voiced 1959SLP circuit — Murray's JCM800 has tighter gain staging and more mid-focus. I've pushed mids to 7 to compensate for the Plexi's slightly looser low-end and cut treble to 5 because your Les Paul's humbuckers are already darker and hotter than Murray's Strat single coils. The original Strat brightness is naturally offset by your Les Paul's warmth, so no treble boost needed.

PRO TIPMurray picks aggressively right over the bridge pickup pole pieces with a stiff pick (1mm+) angled sharply — this attack is 50% of the tone. Your Slash Les Paul's Burstbucker pickups will compress slightly more than a Strat, so dig in hard to get that same percussive snap on the galloping rhythms.
