Had this exact problem 6 months ago, called support and reset the unit.
Been working fine until two weeks ago, tried to reset again but that didn't help this time.....
Any news on the cause of this problem? I bought my kpa used so I really hope I don't have to replace it!
I've had the exact same problem 6 months ago, contacted support and reset the unit, problem was gone.
My KPA has been solid ever since, but two weeks ago the popping occured again and it got no input from my guitar anymore.
Tried to reset it again, but that just solved it temporarily. Next day, same thing..
Any official information about this problem, and how to solve it permanently?
