You are buying the piece pictured.

It\'s a handy size-about the size and shape of a large effects pedal. It runs on a 9-vold battery no wall wart required. And it has a built-in speaker which, although it has a very limited frequency response, provides some nice instant gratification. The top of the device has control knobs for volume, pitch (which sort of \"tunes in\" the range depending on available light), LFO depth and rate. A power switch, square/triangular wave switch, LFO rate LED and the dime-sized light sensor round out the top panel. There\'s a 1/4\'\' audio output jack on the side panel.

The piece is hand made by Professor Television and is in perfect working condition. See pictures for details of actual item shipping. Theremin will ship well protected, buy with confidence.
