I’ve been learning guitar for a few years now. I did in person lessons and did learn the cowboy chords and some theory. But I was a dabbler. I never seriously felt like I was progressing. Tony has changed that. There is so much truth behind the “guitar routine “. And now I feel I have one and it is paying off. I am noticeably gaining skills and having way more fun playing now then ever before. I definitely recommend Tony’s Acoustic Challenge.
