Why these settings

Your RG550's Wizard neck and likely V7/V8 humbuckers are close cousins to Vai's JEM — same Ibanez DNA. The GE150's USA model replicates the Carvin Legacy's smooth, singing lead voice. Vai's original was slightly scooped (mid 4.5), but I raised mids to 5 here because the GE150's modeling needs more mid presence to cut through without sounding hollow. Delay mix is critical — 40% wet keeps the trails audible without drowning the attack.

PRO TIPVai plays this almost entirely on the neck pickup with wide, slow finger vibrato and uses his volume knob for swells on the sustained high notes (roll down to 6-7 mid-phrase, swell back to 10). Practice the pinky-grafted whammy bar bends — he never lets go of the bar, using pinky pressure for micro-pitch shifts during sustained notes.
