Thanks for the reply harps, did you finish it or how long have you been working on it/with it?
Yes, I read the whole thing, and even understood most of it

, but I haven't been doing the exercises like I should. I completed the written exercises in the book, but not the extra ones that really push home the knowledge that you need to learn the fretboard. I gotta work on that.
Justin is not a spoon-feeding type of teacher. By that I mean that he doesn't tell you every single piece of information like you were a 5 year old; he gives you the info you NEED to know and lets YOU fill in the blanks and connect the dots. RUGS Pt.1 isn't about book learning, it's about teaching you how to think about music theory. You don't just memorize charts and diagrams, you DISCOVER music theory with his help. I am SO looking forward to the next RUGS lesson!
Definitely buy the book. If you don't like it J will refund your money. Here is a copy of the Terms and Conditions:
Terms and Conditions
Basically, if you don't like it, send it back in 14 days in perfect condition and I'll refund your money. If you've damaged it, that's not cool. If it's damaged in transit, send it back and I'll send you a new one and refund your postage. I have to put up an 'official' terms and conditions - but I want you guys to be happy, so please contact me with any problems and I will do my best to help. Thanks
