I agree with Superhuman regarding Hendrix. A god to me as a youngster. The reason I picked up a guitar. I loved rock music and the guitar was always mt favourite element, but Jimi made me want to play. Unoveratable in my personal opinion. Jimmy Page is not under rated by anyone I know.

Tough question all the same. Paul Gilbert springs to mind as over rated by some, very skillfull, technically enviable, but WHERE'S THE FEELING ?

Under rated . . you tube search for Anastasia Bardina , I'm sure she's not under rated by anyone who has had the pleasure of listening to her, but she is certainly under known.

ps, Angus ROCKS ! but perhaps his less flambouyant brother Malcolm gets less credit than he deserves, and I'm pretty sure he is the true guitar genius behind AC/DC.

My humble opinions anyroads.
