These are the newer SMD type of the Voice Changer Megaphone Toys. Casper’s notes were roughly used, due to the board layout being revised, but it’s mostly all there nonetheless. Added input and output 1/4″ audio jacks for use as an effect pedal. There are four various sized potentiometers used for the pitch bends, and a 3 way mode selection switch for pitch up, pitch down clean, and pitch down dirty. Bend On/Off switch so the toy can be used as normal.
Video coming soon.
