Prototype thumb piano with built-in amp and speaker.


Shows thumb piano tine lid and can internal view, in this instance with a Smokey Amp and added rheostat. The Smokey amp has no output control so the rheostat was added to provide volume control.

At low volume the instrument sounds normally electrified but at mid and hi volume the thumb piano becomes a feedback unit as the vibrations of the speaker are cycled into the piezo. Interestingly, at that point the pitch and tone can be altered by gently applying and varying finger pressure on the tines and lid rather than plucking.
