I play guitar and bass, but guitar is my main instrument. Bass is just when there's no guitars around :lol:
I've been playing for 3 years now. I'm not great, but I guess I can play some technical stuff pretty well. Meh, I'm a metal guitarist, technicality is a must.
I'd say I take it pretty seriously, I'm in a band and we're close to recording our first demo (We've only been together 3 months). I just love playing.
