For some reason my KPA Rack quit working in that all I hear are loud clicks and pops out of it. With the guitar plugged in I get no lights on the input and no sound at all.
I had just hooked it up to rig manager to copy a couple of rigs around, and am wondering if I got into some sort of state, as opposed to it being a hardware issue.
So my thought was to do a factory system reset - wipe it completely clean - and restore in pieces from backup.
However, when I did the "hold system key while turning it on" thing, it didn't wipe it clean of all the rigs and performances.
Then I tried holding down soft button 1 (the left one above the display) while turning it on, as I've read, and that did nothing at all.
I'm on firmware 3.3.11... whatever the release version is.
How do I reset this thing to determine if it's hardware or software related?
