The cajon is a Peruvian percussion instrument, and a favorite among hipsters and poor college students at the moment. Simply put, it's a box that you sit on and with your hands. If you look up some videos of folks playing the them, you'll quickly see that they can produce a variety of sounds, especially considering the fact that it's just one box. A blue grass group played at my church a few months ago and they used one. I looked at it and thought, "I could build one of those..."
So I did.
Since I'm a guitarist and a member of the Cigar Box Nation, it features a license plate (which can be slapped for a kind of cymbal sound [by which I mean a cheap, trashy cymbal sound just perfect for playing with a CBG]) and f-holes:
Hopefully I'll post a video sometime of me on a CBG and some one who can (unlike me) play drums on this new fangled old fashioned license plate cajon.
