Neal Schon- he is one of if not my favorite guitarist. He can shred, but choses to do so in a melodic and not "show off" way. His solo albums have great melodies and his tone is one of the best out there . Really inspired me on guitar
Johnny Marr- I love guitarists that play well on clean. Just something amazing and simple but full about his playing
Duane Allman w/early Dickey Betts
Derek Trucks and/or Warren Haynes
Jerry Garcia - I don't actually listen to him much these days but I sound more and more like him... spooky
Trey Anastasio (he's one you kinda have to be able to listen to him all day to listen to him at all )
Jack Pearson - you could listen to this cat for YEARS and not get bored
Pete Carr w/ Jimmy Johnson on anything that came out of Muscle Shoals
I've also listened to nothing but Charlie Christian for a week
My first thought was Buckethead. That guy has covered pretty much every genre imaginable. I'm sure there are others that would fit the bill for me, but he"s definitely the prime example of a guitarist you could listen to all day.
That tone. Those licks. Could listen to him forever.
Permanent Vacation came out the year before I was born, my dad has always been a fan and so I've been listening to that album for as long as I can remember, so, quite naturally, Joe (and Aerosmith) are a favourite!
