I've been having a great time since starting the 30 day challenge. Over the past ten years I've taken on-line lessons, in-person lessons, and followed guys who teach songs. Despite all that, I've never really made any significant advances. Tony's sessions have been so enjoyable and informative. I find myself looking forward to my guitar time each day. Although I'm familiar with the cords and some of the scales, the review has been fantastic. I've made significant gains in cleaning up cords and transitions. I've played 13 days in a row. Some days on 20min and others over an hour. Loving every minute of it.
