To be honest I don't think any successfull guitar player is over rated or under. I feel it is what you bring to the table that sets you apart and to each his own. But the most briliant guitar players I have ever heard are little known and some are local guys. To say who have impressed me the most and are famous, and who hasn't, that is a different subject. Impressed: Jimi (of course) Dicky Betts,Duane Allman, Derek Trucks, Warren Hanes, Steve Morse, Albert King (and all the king bros for that matter hehe) Walter Becker, Larry Carlton, Jango Reinhardt,Steve Morse, Johnny Winter, Chet Atkins, Mark Knopler, Alvin Lee, Steve Ray, Carlos, Los Idios Tabaharas, George Harrison just to name a few off the top of my head...(this list can get extremely long)And Unimpressed by most of the now guitar players that don't extend their instrument beyond noise, tho I do respect the athletisism it takes to play some of those rythems =)
