I recently found a Laser Phase pedal in a yard sale. It was very cheap so I took it home and found out it's a cool sounding pedal. It says PH310 on the pcb, which I found out was made by Yu Brothers (Coron) (thnks effect database) and also by companies like Tronix (hence the video). I already did some work tracing and did some photoshop magic, but I really need someone to make sense out of it (schematic or new pcb layout). I have not traced before. Its a very slow progress. Here's my contribution so far:

Pretty cool. I have a collection of Yu Brother effects. Right now I have about 12 plus assorted mics and other stuff.
