Hi, I have a problem with my Kemper Stage.
As you can see in the photo, when switched on and also during use, the effects have a blue led on.
This problem suddenly appeared to me.
Has anyone had the same experience? Did you manage to solve it somehow?
Sorry for my english.
Thanks!
It’s no big deal and nothing is wrong with your Profiler. Go to:
Rig Menu - Page 6 Rig Effect Buttons.. Clear all 4, then reassign the effects as you prefer.
Yes, I guess you've assigned two effects to each one of the effect buttons, nothing wrong with that, but if you didn't mean it, just need to clear those assignments the way the manual explains, just like Ruefus pointed in the previous answer.
Hope it helps! 
i tried but unfortunately this is not the case. the LEDs also light up without having inserted any effect. I have contacted Kemper and they say assistance will be required.
Thanks everyone for the suggestions
