I strongly recommend Active Melody for guitar lessons for the beginner to the advanced players. Go with the premium membership; it's less than $70.00 and you won't be able to get through all the material. There are instructional videos, printable tablature, on-screen tab viewer that you can slow down while you're playing, and downloadable backing tracks.
I haven't seen anything like this instructional website ever. It would cost you $70.00 for 2 hours of lessons-here you get 100s of hours.
Sign up at www.activemelody,com and pay for the premium account. You won't be disappointed.
