Telharmonium
Here’s another amazing and somewhat old one: Google “Telharmonium”. It was basically a precursor to the Hammond organ, but being pre-vacuum tube, it’s tonewheels had to be large enough to drive all the phones in a city at once! A real steampunk monstrosity.
Thanks Tom.
In reality this was a very short time ago. Amazing how far musical instruments and technology have come in such a short period of time.
Great post!
