Hi there,
So glad you're checking out GT for your guitar lessons.
If you know how to play a couple simple songs, and switch open chords easily, and you can easily run up and down a simple box scale pattern, you can start with either Guitar Fundamentals level 2 or if you want a challenge, go for the experienced lessons.
But of course, everyone is a little different!
