best non-guitarist, guitar players are..?

henryhk, im with you on the neil young deal,IMO neal is a great sounding guitar player but isnt even thought of as being proficient.

gohstrider45,FZ was a highly regarded guitar player & composer & i consider him to be 1 of the all time best.

mike.

On the lighter side...

Jack Black (Tenacious D)
Adam Sandler

just my goofy 2c

Ellery

Hugely successfull, and terribly untalanted, but has made an impact on the music scene;

The Edge

Walter Becker by the way, is actually quite good, and has
the sense to get someone more capable to do what he cannot.

completely agree w/ Zappa, Prince, Edge (though both Zappa and Prince are certainly technically proficient!)....the others I don't know well

how about also
Joe Walsh
John Butler (check this guy out from down under!...jam band)
Lowell George from Little Feat
Monte Montgomery (if u do not know u gotta check him out: acoustic w/ an attitude)
Peter Frampton (I know, but then again...)
Bonnie Raitt
Tom Petty (when he wants to)
Bruce Springsteen (Bad Lands!)

Paul McCartney is actually a very good guitar player, not just bass.
