Eddie Van Halen
Billy Joe Armstrong (cut me some slack, I started playing in '95 and I was 11)
David Gilmore
Influenced:
Jimmy Page
Slash
Eric Clapton
I broke the two up because while I was inspired to start playing guitar by Eddie, Billy, and Dave, I don't play anything like any of them.
The other three are the people I actually play more like, or in Slash's case aspire to play like.
