Don't think I ever added to this thread.

Underrated -

-Steve Stevens (Though a rock guitar player worth his salt would probably not argue it either)

-Neil Geraldo (Pat Benetar). Seriously, there is genious in his playing. Not from a technician's standpoint but his ability to phrase and adapt styles is really something.

-Nancy Wilson (Heart). Go ahead, just whip up that acoustic intro to Crazy On You and tell me that isn't something...

Overrated -

Harder to do cuz who really wants to rip on another guitarist...Well, LOTS of guitarists do but they shouldn't. Maybe Vinnie Vincent (if anyone recalls him)..Was in Kiss and Vincent Vincent Invasion. Good songwriter but that tone and the almost atonal overplaying was not my bag.
