This quick instrument was an experiment in three different things. It's been made from the leg of a piano stool and some scrap wood, nails, washing line wire and a motor from an old cd player.
The main reason for this build was I wanted to see if an acoustic version of the Droneitar would work at all, so this little instrument has a motor embedded in the very base of the neck with a small piece of frayed string. This should, in theory, make the strings hum.
It didn't work quite how I'd hoped, so I added a quick piezo contact mic to amplify the drone a bit and it sounded better.
Another thing I wanted to try out was a quick and dirty way to make a hollow bodied instrument, you can see how I did that in the progress pics.
