I have been giving JamPlay.com a shot for a more structured aproach to learning the Guitar other than just Youtube videos. I am enjoying their Guitar 101 course by Chris Liepe. The Guitar 101 videos are on Youtube but for the full course material of .PDF's, MP3's and Guitar Pro .GPX files you may have to join to try it out. I only have temp access for a month but I am checking it out.
I am also using the Guitar Pro Android app to use .GPX guitar tabs. There are quite a few .GPX Kingdom Melodies made by a Brother here at OneDrive. He plays some of them at: Kingdom Melody Guitar on Youtube.
