i struggled a long time with learning traditional theory, modes never clicked for me, learning how intervals made up a scale was booooooring. I found reading Fretboard Logic gave me a intuitive, visual representation of the fretboard that's allowed me to develop my knowledge of traditional theory more. It seems like guys who are really about teaching theory traditionally don't like the book, but if you're baffled and struggling, it couldn't hurt to check out. Volume one is really basic, Volume 2 goes more into detail about different scales and chord forms.
