In the last panel, Rachel is referring to a Rhodes Electric Piano, which is a very cool instrument.  It has keys that kick hammers like on a regular piano, but rather than striking strings, they strike tuned metal tines (bells – like an over-sized glockenspiel).  Each of these bells has a magnetic pickup (like on a guitar) that translates the physical motion of the bell into an electrical signal.  Plug this signal into an amp – particularly a tube amp with just a touch of overdrive – and you’re in EP tone heaven.

I have some rather pretty pictures of my amplifier project to show off, but they’ll have to wait until Thursday.  See you then!
