John, I recommend Connecting Chords With Linear Harmony by Bert Ligon. It's a college text, I think, and I learned about it on this site. The author used to post here as well, I believe. It's not a guitar book, but rather a non-theory-based analysis of lines played by well known jazz musicians, and categorization of them into three categories of paths between chords. I practiced it by playing the 2-4 bar lines in the key as written but in each of the usual five major scale shapes on the guitar, in more than one octave as available. I found great value in this book. It sounds to me what you're looking for. it's widely available.
