That he can and even if you only got maybe 70-80% of the tone down, actually being able to play properly in the EVH style (that specific swing in "I'm the One" for instance) will truly help sell it more, than some guy who's got all the right gear (mystery pots on the back of amp and all
), but plays it half-assed.
I know a 'local' guy who's a great player in a VH tribute and he does the EVH stuff on a Marshall JVM. His playing skill just helps to sell it.
My own 'EVH' signal chain to somewhat mimic the tone isn't true to the original either;
Charvel So-Cal ProMod MIJ (alder body, maple neck (now THIS is important! MAPLE FUCKIN' NECK!!!), Super Distortion bridge, brass block under Floyd-->MXR Phase 95-->MXR Micro Flanger (vintage)-->DOD 250 (modded, for boost)-->Engl Savage 60 mkI into Marshall 1966B (Mesa V30+'85 vented T75). FX-Loop: TC Alter Ego V2 set to Space Echo, TC HOF Mini Reverb with plate patch.
But for a little at home jammin', it gets it done.
