My friend Justin Sabe made this nifty cigar box sitar and did an Instructable and a short YouTube vid for it.

I decided yesterday to stop thinking about how to do it and finally make a cigar box sitar. The main difference is the buzzing bridge. In many ways, it’s easier to make than a cigar box guitar/ukulele because it’s fretless and doesn’t have any critical measurements to make it in tune. It took me as long to construct as my girlfriend to take a medium-length bath and about three times longer than that to fine tune it for a good rich buzzing sound. As you can see, my cat likes it just fine.
