Howard Roberts, Tommy Tedesco, Barney Kessel, Tal Farlow, Kenny Burrell, Hank Garland, etc. The Jazz studio masters were the best of the best. Then there are the Nashville session players from the 50's and Classical legends too. There are several different genres of music besides Rock and most have some astoundingly talented musicians on guitar.
Consider all the genres of music Tommy Tedesco recorded in. He even did Classical recordings on a nylon string guitar playing with a pick (in one of his seminars that's on YouTube he talks about doing that). How many other musicians could pull that trick off?
