What are good exotic sounding chord shapes, I'm thinking exotic as in Steve Vai's Freak Show Excess. What kind of shapes does he use in that song?

Thanks.

Chords aren't shapes, they're collections of notes.
Someones knowledge of guitar companies spelling determines what amps you can own. Really smart people can own things like Framus because they sound like they might be spelled with a "y" but they aren't.
