I got this at KB toys. It was the first toy I found to try to circuit bend. When I first opened it up, I thought wow, there are no components that I know in here. I poked around a bit, and then closed it back up unbent. I later learned what surface mount components were. It took me a few years before I ran out of things to bend, I opened it back up and found the pitch resistor, and replaced it with a 1M potentiometer. This is the smallest resistor I have replaced yet. This thing now kicks out some wicked bass. I had to replace the speaker to make room for the Pitch Knob. It has a reset button, and a mono 1/8 inch output.
