Sure, every band geek has heard of the mythic contrabass sax. But I bet you didn't know there were contrabass clarinets and french horns or subcontrabass recorders, flutes, and... uh... this thing. On the other end of the spectrum you've got the sopranino recorder, saxaphone, clarinet, and ukulele.
Xaphoon! It's a saxophone! No, it's a clarinet! It's dirt cheap and it fits on your pocket! Apparently these have been around for twenty years, but I've never heard of them before. I've ordered myself one of the plastic ones. Has anyone here played one of these things?
