Wow. Where to begin to respond. First know that there is a chat on the home page. Victoria usually is the one to answer and she is very prompt, 10-30 minutes typically. Here is a link to the Quick Start Guide which gives you a roadmap on how to get started here.
After 30 days the next step is 5 day routine. Then you can move on to the Daily Challenges which are so much more than a “four week rotation of skills with ie: Blues, Chords, Strumming, Soloing”. Every week you cover the 5 core guitar skills: Monday – technique, Tuesday – guitar lick, Wednesday – Improv (soloing/scales), Thursday – Rhythm guitar and finally Friday – Chord transitions. You do this every week for as long as you are in TAC. There are many members here who have been doing it for 5 years, several more than 10 years. They all still find it valuable!
I love this program, I tried a number of other ones as well and TAC is easily the best for it’s structure. Could it be improved? Heck yeah, it sure could but it’s still an excellent value.
