You may call it silly. You may call it disgusting. I call it a fun, little project.
I got this vintage bedpan from eBay. After sanitizing it a dozen times, I felt that I could work on it. The neck is poplar and the headstock is maple. The cherry fretboard has 17 frets and has a baritone (19 inch) scale length. The tailpiece was taken from a child sized guitar.
This ukulele can be plugged into an amplifier with the help of a piezo rod embedded into the bridge. It is connected to a potentiometer that controls the volume to the 1/4 inch jack.
See it in action!
Here is another one that I made a couple of years ago.
