I've been playing guitar for 5 years now and although I'm a fair guitarist, played in a couple of bands and can pull off some tricky songs, I've started to get the feeling lately that I'm just a guitarist and not a musician. My music theory isn't bad, passed my ABRSM Grade 5 back in November, but I really don't know how to get started with applying it to guitar.

I know it's a long process but I'd just like some advice as to how I should get started and eventually get to the stage where I could meet another musician that I don't know, turn up and play.

Thanks in advance.
I highly recommend Scotty West's Absolutely Understand Guitar course. It's expensive but it's great for music theory relating to the guitar.
