Online guitar lessons seem to be the popular thing now.  There are hundreds of products out there that offer free and easy guitar lessons.  Some of them make claims such as "Learn guitar in 3 weeks" or "Play like a pro in 2 days!"  While I think there are several high quality sites out there, no site or teacher can promise these claims with any certainty.  The only way to become a good guitar player is to practice, practice, practice!  So remember when you sign up to learn guitar online , it is still up to you to put them time and effort into learning.
