Despite having picked up the guitar decades ago, I've never progressed beyond simply being a 'strummer'. When I decided to get serious about guitar, and bebop in particular, I took a chance with Richie's course. I spent several months working through the material on my own. While the material exposed me to a wealth of knowledge, I was struggling to apply it to my playing. Once I began studying privately with Richie I was able to solidify areas I'd previously glossed over while benefiting from his years of experience with the bebop idiom. I highly recommend his course.
