Query: Great Book

Ganapes does a great job with this book. It starts off with the bare bones and takes you all the way to a pretty advanced stage of playing. By the end of the book if you put in the work and time you will know inside and out of the blues progression as well as how to navigate the fretboard with confidence. The studies of each chapter are tasteful and are a great way to give the reader insight into typical licks and riffs. The only reason I didn't give this book 5 stars is because Ganapes does get a little vague at times, particuliarly with chords. Sometimes he leaves out theory behind certain chord substitutions and I found his sections on thirds and sixths a bit confusing. However these things come up again in his 2nd book More Blues You Can Use so this might be by design. Anyhow, this book is an amazing accomplishment in teaching blues guitar. Ganapes also has a forum online at [...] in which you can ask him questions (how awesome is that!?!). I highly reccomend the book.
