I think Zakk Wylde is a pretty versatile guitarist. He does/did the Ozzy thing, he's got the Black Label Society stuff which consists of heavey stuff along with lighter upbeat accoustic stuff. I've heard him do Hendrix covers. Even heard him do some country "chicken pickin". I'm not saying he's THE most versatile guitarist. All I'm saying is he's able to cover many different styles very well.
