Like Merwood said, "plenty here to learn".. You can purchase a month at a time to try GT out, and it is refundable if your not satisfied..
If you are totally unfirmilar with guitar, you start with the core lesson fundamental 1.. Lots of members brush through the fundamental no matter what stage of learning thery are at..
You can even get help with set-up info, repairs, tones and effects.. Anything to do with guitar and guitar music is here and more comes all the time..
Good luck and keep on pickin'
