Check this out. There have been threads in the past asking if a theremin would be good for a person with tendonitis who can't play bass any longer. Don't know the answer but this proves one CAN play bass on a theremin! I can see a theremin built into a standard bass guitar shape with pitch on one hand (neck) and volume on the middle of the "guitar". Might be cool!

Hey, I haven't even IMAGINED anything quite like this was even possible!
