Anyone else really enjoy picking up new ideas from books? There are a lot of crap ones out there, but some real gems too.
Pic related is what I'm working through now and it's fantastic. Randy has another book that's a more general introduction to jazz guitar, which is probably the most useful information dense guitar book I've ever found.
I've heard good things about that book, but never had a look myself. I definitely put really learning the fretboard off for way too long - felt like an asshole once I put in the time on it and realized how much it opened things up for me!
