I had it happen today.i turn it off and back on.bingo it's gone.all of my more sufisticated equipment does stuff like this ,I bought a 600 dollar wireless system for $80 because it's about one out of five times didn't power on when they hit the switch.i scored.and the best wireless that line six bought the company out to gain the rights.relaxe .turn it off and on. Or reboot it's a glitch in the off and onof millions of signals in the thing.if not send it in.but a lot of things in the digital world become confused.am I on or off.you just remind them.both are great unit's and if you can't dial-in sound yet,I'm finding it's us not it
