I've had my Kemper Stage since November 2022. Since the day I got it the two left knobs under the display (in between the Gain and Master Volume) have been very faulty, as in unpredictable and impossible to fine tune (jumping all over the place) even when not touching them, they will adjust. I just ignored this since I can bypass that and use the PC Rig Manager.
After procrastinating for too long, I finally decided to figure this out since I won't always be able to have access to the Rig Manager.
Today I tried to use electrical cleaner because I thought dust or dirt would be the problem.
Unfortunately, the problem persists.
What solutions are there to fix this?
