Who didn't see this one coming lol.
Honestly there are far too many that I like and try to emulate, all of whom are fucking awesome in their respective "sub" genre's.
Malmsteen, Hendrix (fuck yes), Jimmy Page, Hammet, Vai, Van Halen (no shit lol), Morello (I know what you might be thinking, but this guy IMO is good, really really good), ahh too many to list, but those are the ones that immediately spring to mind (its not in order by the way).
Utmost respect for these guys, best of the best.
Oh ya before I forget, Neil Young lmao M Thomson and J. Root (shit I just signed my own death warrant lol)
edit: And I just know that when I see other ppl's picks, I'm gonna slap myself for not remember their name(s).
