I would seriously reccomend that anyone starting guitar takes at least a few lessons to start and then delve into music/guitar theory right away. If you ever want to become a -serious- musician, you need it. When your jamming along and the bass player nods at you to solo and you don't know wtf key, scale, etc, you look like a total idiot and nobody takes you seriously after that. I went back and learned that stuff after I had already taught myself to play, it sucks. Like trying to put a bomb back together that just exploded. Save some trouble in the future and learn all that shit now.
