I got this off Ebay recently. It did not take long to bend this one, as I found all the bends in the Circuit Bending Book by Reed Ghazala. I think I will open it back up and search for more bends at some point. But she is a real horror movie music maker. Its got a 10 switch panel that is controlled by the knob (flux dial). I wired in a 1/8 inch mono output with a speaker on/off switch, and a 1/8th inch mono input, with a microphone on/off switch.
