A friend has decided to start playing guitar and asked me for some advice regarding online and DVD lessons. They live in a small town so want to learn that way, rather than with a live teacher. Other than Justin Sandercoe's site, Doug Marks' Metal Method site/DVDs, and the Gibson Learn & Master series I am not really familiar with any online or DVD learning resources. Can anyone here recommend decent ones? If it matters, they want to learn to play both electric and acoustic.
