I picked up a couple of cheap M Audio expression pedals, but no matter what I do they won't go to the end of the calibration slider.
When I use the "Vinyl Stop" effect it doesn't go to the max, so it doesn't sound as cool as when I use the Mission pedal. Also makes them useless for volume.
I'm sure it's something simple like "those won't work properly with the KPA" but want to be sure.
