Variable Speed Modified Cassette Walkman
Selectable Photocell/ Knob Control/ CV Input
w/ AM/FM Radio, Voice Activated Recording Mic, and Headphone Out

Control tape speed via knob or selectable light reactive and voltage reactive modes. Putting the pitch knob in a fast position will increase the amount of influence from light or voltage. Brighter light near the photocell will result in slowing the speed. CV mode works best with LFOs, Oscillators, Sequencers, etc. 

Runs on two AA batteries or optional usb power.
