Even though I'm an experienced, "intermediate level" player, I took on the 5-day challenge freebie. I was impressed at Tony's clarity of instruction and straightforward presentation of the fundamentals. So I enrolled in the main TAC course.This was what I needed: review and practice of the fundamentals. Before, I had grown careless and unfocused about "cleaning up" my playing; hitting clunker notes, being slightly off-time and so on. This course is the solution to get me back on the horse and see how good and how polished I can be.Even though I've advanced to earn several figurative tae-kwon-do guitar belts over my playing career, I love Tony's course to get me to "put the white belt back on". I'm only two weeks into the course and this is high value.
