What about Pete Townshend, Eddie Van Halen, and Steve Howe, Jimmy Page?
All great guitar players also to add to the list.
I was flipping through channels about a year ago and stumbled on a blues fest taped at the house of blues in Chicago (2010). I saw a part where Steve Winwood was playing guitar with Eric Clapton at the end. I was like WTF? Steve Winwood on guitar? I always knew him as a keyboardist. He was not bad. It was entertaining to watch. He may not be an "all time great" on the guitar, but he can play pretty well.
