I play guitar (and banjo, to an extent) and sing.

My guitar is a $250 Ibanez. Not supreme in quality, but it sounds decent enough when you plug it in. When I graduate from university in a little over a year I'll get a Martin.

I play folk music, traditional and contemporary. I do not play in a formal band, though there are numerous people that I perform with, depending on the setting and who is available. I'll occasionally play a break set for someone, or during my own shows have some of my colleagues accompany me. It's all very informal.
