This was made from a Boo-Bah toy. It really doesn't do a whole lot, hence the name, Boo-BLAH. The Circuit board was re-housed in a can that a wrist watch came in. Bends consist of a red push button trigger switch, pitch control pot, toggle switch for added distortion through a capacitor, 1/8" input jack for photocell control of pitch, and a 1/4" audio output. Also has a small internal speaker for stand-alone operation.
A pretty annoying little bugger, just like the toy!
