Hi girls & guys,
at last nights gig the tuner on/off switch stopped working right in the middle of a song and I couldn´t leave the tuner mode. The signal is off course muted when in tuning mode. I had about 10 seconds to run across the stage to my kemper and use the chicken head switch to get me out of the tuner mode. Just imagine, one of the 5 slot switches breaks and you´re stuck on a clean preset - while playing METALLICA or so. 
However, there were signs of warning before. When I got the remote, the tuner switch had a little different feeling to it. And on some gigs in the past, i couldn´t activate the tuner on the first try. I had to press the tuner button 2 - 3 times.
I´m pretty sure, I´ll have to send in my unit. Or am I missing something???
