I play guitar and flute. I can play a passable keyboard and I wish I had more time to learn about midi.
I used to play harmonica while playing guitar (yes, deep down, I'm a folkie). Then one day I realized the world is filled with people playing their harmonicas... badly.
I'm currently building guitars and I have several projects on the go. I have an octave XII almost finished. I'm putting the finishing touches on a telecaster.
I'm excited as I recently jumped at the chance to get an acoustic bass neck for real cheap. I've got a 12 string body that I've had for a while. You know how an acoustic neck on a 12 string body will sound like (probably sound like crap). I'm going to play it until I get better and then invest in a decent bass.
