So, I recently gave this course a shot. I found that Mr. Johnson does have a fairly solid, but basic knowledge of the guitar. I sincerely believe that there is potentially something to be learned from his courses. However, MANY aspects of the product prevent the potential of this course to shine through. The basic quality of the audio and video on the DVDs is absolute garbage. Mr. Johnson's attire, posture, and teaching props are 'basement' quality at the very best. Just a little more effort to improve the impression that one gets would go a long way. While Mr. Johnson may have a basic knowledge of the guitar, he has extremely poorly developed skills, and struggles embarrassingly to demonstrate his points. There is no evidence from the courses that he actually has ever had any formal guitar education, or that he has put any education that he has received into good old fashioned practice. Putting it bluntly, he sucks at playing a guitar! In addition to all of this, (which I was willing to overlook if I could have learned something new -- remember, I recognize potential here!) some of the DVDs were blank, and many others had no sound track, only video! How can you learn anything that way? I did have a very good response to my question about where the 'extras' were, and was able to find them all on the web site. There is some great information in these, especially about how to learn guitar the right way and how to avoid learning the wrong way. So, I have sadly requested a full refund, based upon his one-year unconditional money back refund policy. We'll see how that goes. I'm giving them 2 business days to post the refund to my credit card, or to contact me to get the process rolling. If I don't hear or see a response from them by then, I'm going to contact my credit card company to reverse the charge from that end, file a formal mail fraud complaint to get an investigation going, and may even contact an attorney. I suggest that anyone else who has any difficulty with this dude do exactly the same thing -- just Google "mail fraud complaint" on the web and off you go. The more complaints that are registered, the better the possibility that the authorities will go after this guy. HOWEVER, IF HE HONORS HIS REFUND POLICY IN A TIMELY MANNER, NO HARM, NO FOUL!!!!!! (Can ya feel me Claude? I mean absolute business here, and I'm not some kid who doesn't know what I'm doing. If you are sincere about your business, do the right thing, improve your product, continue to learn the art, and good luck to ya!
