I have a GT22 with two Mission Engineering SP-1RJM connected, which i use with my Axe FX III. The Axe won't register the entire sweep of either of my expression pedals, i.e. from 0 to 100% (or 0 to 10, depending on parameter i want to control). I have tried calibrating both pedals several times, and each time both pedals stop at 99.2% or 98.4%, depending on which parameter the pedals are controlling, but it's always the same for both pedals. Cliff from Fractal says it's NOT an issue with the Axe FX, so that leaves the MMGT22. I have also opened up the pedals to check for loose parts that might affect the sweep of the potentiometer, but everything is as it should be.
