Two best resources I have found.......
First, Fred Sokolow's Fretboard Roadmaps (available as book and
video, sold separately) really opened my eyes. He now has a
bunch of "specialty" books (for country, blues, etc.) that build
off the first. I think Fred, along with Arlen Roth, is one of the
best teachers I have found.
Second, I totally agree with Abe. You have to find some other
guitar players to jam with. I was strictly a "Guitar George" until
Mike Rice started hosting jams at his place. And when you jam
with Mike, be prepared to take a solo!
Anyway, my 2 cents!
