Well....I have been playing and "stop playing" guitar for years.....
I will say I have never learned guitar in a "step-by-step" way....I mean, I know how to read a Tab and I can play it through endless practice, but that is all. I have never learned the basics like:chords, scales, etc...
After years, I think now it is time to learn how to play guitar "for real". I will see how far I can go in 1 year, with this outstanding website.
Cheers~~
