Re: If you had a time machine....
I've never really wanted another person's guitar, be it because it was cool or because it was his, the closest thing though would be Criss Oliva's ESP i.e the "Gargoyle Guitar" but mainly because if there'd be even a cold day in hell's chance of me sounding even remotely like the guy did, I'd take it. Most expressive player I've ever heard and the only guy whose very playing has stirred actual emotions in me.
(with his student and bandmate Chris Caffery being a somewhat close approximation, and don't get me wrong, the guy is a stupendous player but he's not quite the same).
