Hey wassup people? I found this site last night looks pretty cool, I have been playing guitar for about 9 to 10 years with some time off in between but I am trying to get back into it hot and heavy. I was in a couple of go no where bands when I was younger and left them because the guys would rather drink or smoke weed than practice so I said C ya. I see a lot of talk about Music Theory on here I don't know how to read music lol I use some tab but I like playing by ear and making my own stuff up. My only problem I have is I fell into a Blues rut I can play any SRV you want but when I try to play metal scales or licks it all comes out like a metal blues :D again I would rather not play someone elses music I want to make my own licks and riffs so does this mean I need to learn about Music Theory?

Thanks for any input
