Guitar Instruction Tools by Cary:

The Complete Guitar Personal Instruction Program was created in 1995,
used by hundreds of my students, and provides everything from chords,
rhythms, lead, theory, tablature to note reading and playing classical. 
By the time you finish the course you can play just about anything. 
Use the pdf book along with the web app to get the audio files
associated with the songs and the lessons.
