I've had mine for a week. Setting up for a weekend gig at lunchtime today and button 1 decodes to stop working. Tried various things but no joy. I arranged with the supplier to collect it tomorrow. Went out for a couple of hours and on my return, switched it back on and all is well again !
I have checked it a few times this evening and it is all working. I have cancelled the return for now to see how it goes over the next few days. Never had anything like this in years of Line 6 ownership. Does anyone from Kemper read this forum?
people from Kemper do read this forum sometimes, even Mr CK himself contributes on here occasionally. Both me and my bass player have a stage and all our switches work fine. I’d contact support as they will be able to help you properly
