My nephew got his first guitar!

Well this question could go one of two ways.

If you're referring to the first instrument I ever got my hands on and learned how to play reasonably well, I say piano, because my parents had/have one.

If you're talking about the first instrument I owned myself, it's a bass. My parents bought me a bass for my birthday way back in 1994. A couple of years after that I had enough to order my guitar from Musician's Friend, so I have a REALLY old bass and a relatively old guitar. Both still work fine, and I am getting to be good at both despite having to teach myself almost everything
