The main parts for this instrument (besides the actual satellite dish) were taken from this electric guitar that was purchased at a garage sale. The neck and tuners were used, along with one of the pickups and one of the potentiometers.
The paint was painted black before it was mounted to the dish. Some wooden blocks served to set the neck at the correct angle.
This guitar used a top-loading hardtail bridge purchased from eBay. The single-coil pickup is connected to a 500K ohm potentiometer. The wiring is just like this diagram.
