actually, Evo II isnt even used by steve vai.. it's just Evo with a diff sound (supposely better, but i believe is subjective).
Steve vai uses Jem 7V. Swee lee sells it 53(or 6)(something something). So yea. it's 5000+++++++ before discount.
It looks good on a girl too. Look for Yasi on youtube. ^^.
^ steve vai names his guitars, and he has a guitar called Evo II that's used as a backup for Evo, one of his main guitars. it's actually a prototype of the JEM7VWH if i'm not wrong. but you are also right on the dimarzio
