This online guitar course describes itself as being aimed more towards the over 40s, which is no bad thing. Whoever said that you can’t teach an old (blues) dog new tricks neglected to let Keith Dean (the course instructor for Adult Guitar Lessons) know. And Keith, in turn has neglected to let anyone who bought this course know. And judging by the impressive testimonials, that is a GOOD thing. The Adult Guitar Lessons course comes with a 60 day money back guaranteee for complete peace of mind.
