Jus Oborn (His work on Come My Fanatics rivals everyone. Tripped out, incredible soloing throughout much of the album, as well as Electric Wizard's other albums)

Eddie Hazel (Maggot Brain. This guy did the greatest solo ever in the history of guitar)

Neil Young
David Gilmour
Robbie Krieger (The Doors)
Wino (The Obsessed, The Hidden Hand)
Tony Iommi (Paranoid is loaded from beginning to end with top notch, memorable riffs and solos
Daniel Riddle (King Black Acid... This guy has a great, mellow style that puts you so at ease)
Bernard Sumner (Joy Division)

Best bass players would be

Tim Bagshaw (The greatest BY FAR. His killer heavy, ultra groovy riffs in Electric Wizard's early albums are the best ever.)
Al Cisneros (Om, Sleep)
Peter Hook (Joy Division)
