Love you brother, but disagree completely.
Hammer on's, pull off's, sweep picking, ghost bends...etc..etc.. is technique.
Knowing your way around a fretboard is theory.....IT MAKES NO DIFFERENCE if its standardized Western Music Theory, or a system of organization you came up with yourself.
Stephen Stills from Crosby, Stills, Nash, & Young was not only one of Jimi Hendrix biggest fans, but was one of his closest friends as well.
Stephen has said in many interviews that "Jimi, really didn't even understand what you meant if you said a "I, IV, V progression", but on the other hand, he had a way of organizing his own licks that was unbelievable, and went over all of our heads."
We all have heard the stories that SRV, Van Halen, Danny Gatton, Hendrix
(insert your favorite here) didn't study music theory.
And while this maybe true..... and maybe these fine guitarist don't understand music theory like a GIT instructor, I still protest that they have a way of organizing the fretboard.....even if its their own way.....and even if no one else understands it.
