I am a self taught, as an adult, guitarist and songwriter and I wanted to up my playing game for song writing. I am pretty confident with chords, but I have never played a solo, though I have learned some scales to play a few melodies and riffs. I just ran through the 30 day kick start and found a number of areas to improve, especially with single notes, and confirmed that my rudimentary chord work is pretty solid. I'll be going back to the Blues, strumming patterns (to practice pick attack), and solo lessons regularly as I move forward with the challenges. Wish I had known of TAC when I started learning guitar, you teach the way I learn.
