I just got out of an online guitar training session that was out of this world.  It was the 3rd one for me and they just continue to get better and better.  The first lesson got me hooked enough to want to come back to another.  The second one was challenging but I knew that i needed.  But now that I am into the 3rd lesson I know that I am hooked for ever.  The blues guitar lessons that they have on there are perfect for beginners and really help you learn the basics before you start anything else on guitar.
