I've been fooling around with the bass for about 3-4 years now. I play it mostly as a hobby, since I don't really have much interest in joining/forming a band.
Besides that, I can play a little bit of electric guitar (no shredding, sadly) and acoustic guitar (not properly). I got a harmonica for Christmas, so I've been fooling around with that as well. I used to be able to play the alto sax; I probably can still, I'd just need to re-learn what keys make what notes.
