I've been playing off and on (and not exactly seriously) since teaching myself ~15yrs ago. I have basic theory knowledge but never applied it to guitar, just got used to playing "what sounded good" and picking up patterns I could use. This course made it very simple. Conceptually, it's all very easy. Now I just need to put in the time to get it down in my fingers so I can use it easily. Great stuff, already looking forward to your next course.
