(To Richie) "I have been playing guitar for more than 45 years. For 30 years I have had a great passion for jazz and have been playing rhythm guitar in a big band for 20 years. Likewise, I have been trying to learn to improvise for 30 years, but all previous attempts have brought little. With your course, however, I really have the feeling that I am progressing. It is the best and most effective course ever found in all the years. Thanks for that!!!"
