Why these settings

The Ibanez RG550 has brighter, tighter ceramic/V7 neck humbuckers than Slash's warm Alnico II pickups, so roll your neck tone knob down to 7 to achieve that round, singing 'woman tone'. On the ME-90, the STACK CRUNCH preamp provides the modded Marshall bark, pushed by a mild T-Scream boost for liquid sustain. Treble is dialed conservatively at 5 to keep the upper register smooth and avoid modern fret sizzle.

PRO TIPPick right over the neck pickup with a heavy pick using medium-firm attack; the roundness of the intro tone comes from Slash's neck pickup response combined with slightly softened pick transient dynamics.
