You want to not only know the fretboard but OWN the fretboard?? Get involved with the weekly backing track jam where you post you playing to a backing track and then post it Twanger Central sub forum here. The people are way cool, the regulars don't tell others how to play, they see the cup as half full. And if you asked for constructive critique and no negative criticism you would get just that. And learning the neck? No better way to learn it than by making music with it. A year of doing this fun weekly bt will forever improve your musical thinking and your playing.
