Hi all, I have a nice red Mission EP1-L6 expression pedal that has become unstable. When I use it with my HXFX and look using HX Edit, the software-registered position is unstable, it moves up and down rapidly without touching the pedal. It's quite old, from 2011, and used quite a lot. Could the potmeter be worn out? If so, does anyone know a good address for a replacement potmeter without sending the whole thing off to the USA for repair? (I live in the Netherlands, so USA is not handy...). Thanks, Steve
