Why these settings

The Plexi 1959 is the authentic platform, so cranking Volume I (gain) to 8 into power-tube saturation delivers the core brown sound naturally without extra dirt pedals. The V7/V8 ceramic humbuckers on the RG550 have a tighter, hotter output than a PAF, so bass is held at 5 and treble at 6 to prevent high-end harshness while pushing mids to 7 for the iconic chewy bark. Jumping channels allows you to blend the Normal channel volume around 4-5 to add low-end body beneath the aggressive High Treble lead bite.

PRO TIPPick forcefully near the bridge with a rigid, heavy pick angled slightly against the strings; Eddie's aggressive pick attack and pinch harmonics rely heavily on immediate string strike dynamics rather than excessive preamp gain.
