Electric guitar, five-string banjo, trumpet and recorder. I can play a little flute, too. I own a trombone and a lap steel guitar, but it's a bit of a stretch to say that I can really play either one just yet.
Update: To satisfy the gear curious out there, I have two banjos, a Deering Calico (one sweet machine) and a Deering Goodtime (my starter banjo and the one in the picture on my home node). I also have two guitars, a Carvin DC127 (poplar) and a Carvin DC727 (seven string, mahogany). Two amps, a Carvin SX100 (which I rarely use any more) and a Tech21 Trademark 10 (which sounds better IMHO and is powerful enough for my church "gig"). The only effects I use very often are a Carl Martin compressor and a Tech21 SansAmp Original, though I also have an Alesis Midiverb 4, Lexicon Vortex, Boss DD5, Dod FX17 Volume/Wah, Ebow, and perhaps some other miscellaneous stuff floating around. My other instruments are pretty nondescript for the most part except for a relatively nice Roessler soprano recorder.
Any of the trumpeters out there want to recommend a good, reasonably priced trumpet (I'm still working with the one I started with in fourth grade some twenty years ago or so.)
