Here are a few to remember: Leslie West, Ronnie Montrose, Gary Moore "Skid Row", Wayne Anderson "Granicus", Martin Pugh "Armageddon", Rick Emmett "Triumph", Rusty Burns "Point Blank", Mick Devenport " Nutz" (not much on the album, but great live). There were a lot of very good to great guitarist during the seventies and the above list doesn't even scratch the surface.
