Signing up for TAC has been incredibly rewarding. I've played rhythm guitar almost exclusively for decades, primarily in groups that did folk, country and early rock - loved to strum and sing. Never had a lesson. In my dotage, I decided to take up as a hobby learning more about how to play guitar, particularly finger picking. Tony's approach suits me well. His methods and presentations are excellent. I've worked on both finger and flat picking, tried to become more adept at barre chords, etc. After the end of 2015, I'm going to go back through all the lessons I've taken, using the tabs to improve my proficiency with each song and technique. I can't keep adding five day challenges -- need to feel better about what I've started to learn!BTW, my guitar is a PRS Angelus. Sold my much loved Collings D2H because it was heavy and not well suited for finger picking.
