Mine are the usual ones:

Van Halen
Alex Lifeson
.. plus a bunch of others I don't know the names of...the guys from the Shadows, Starcastle, the Beatles, and yes.. The Partridge Family... no joke. They were the first songs I ever learned and they were recorded by some of the best L.A. session musicians around.. like Tommy Tedesco. So it was like taking a crash course in studio techniques, harmonies and pop songwriting.

I think I get just as much inspiration from none guitar players though.
Like the original keyboard player for Saga played some incredible lead lines.
Even inspiration from none musicians.... Charlie Chaplin, just because he'd do 200 takes until he got something right and wouldn't accept second best.
Isaac Asimov, for originality and the shear volume of material he put out.
