Learn the theory

I am a bit of a nerd so even playing guitar involves me learning the scales and the musical theory behind...well....making good music!

Ive only had friends so far teach me a few things now and then and mostly its the internet free stuff that i look up to learn. So far its been working for me, lots of helpful ppl out there ready to share what they know on the matter.Here are a few of my favs
