Hello, everyone.
I would like some help from the tech guys. My Expression pedal stopped working. At first, it started to roll back to heel position constantly (0%) by itself. Now it's completely stuck on 0%. So i can't use it to control anything. If i assign it to a volume pedal the patch will go completely silent, for instance. The pedal switch is working normally and is changiing from EXP 1 to EXP, as it should. It just won't sweep, even when at pedal cal. screen. I've tried to flash it again with no luck, so it's probably hardware.
After fighting it, I had it opened by a tech friend. He said the probable cause is an optical sensor pair malfunction. He said i should take it back to him when he has the time to work on it, but gave me the green light to research the part beforehand just in case he comes to the same conclusion after examination at his shop.
So here i come... does anyone know the correct specs and ID for the part and where i could get it??? I attached some pics to help. Thanks !!!!!!
