So I have used the Kemper (Rack, no power amp) for 3 weeks and I am fully impressed.
Today I got scared however.
At band rehearsal the Kemper started to act strangely.
After, say 45 minutes, I am playing a clean sound. and slowly the sound gets more and more distorted. After 2-3 minutes it sounds like full distortion, lost of noise and stuff.
It doesn't matter if I change to different rigs. Awful.
So I shut down the Kemper and restart. Everything is fine and after 2-3- minutes it starts again.
I change cable, guitar, where I get the power from and so on but this is really happening inside the Kemper.
Shut it down a few times, keeps repeating.
So I switch back to my normal amp and after an hour I try agin with the Kemper. No issue, play happy for 1,5 hour.
This makes me very worried. If this would happen during a gig I would be screwed.
Has anyone had a similar experience before? Or any advice on what to do? Everything looks fine again but I am scared that I do not know what happened here...
Could there be interference with my Sennheiser 300 IEM G3 In Ear unit that I have in the same rack?
