Sorry for the "necro bump". Here is the scientific explanation: http://en.wikipedia.org/wiki/Newton's_rings

Makes sense. The pattern changes instantly when I as much as touch the plastic/glass. So I think a defect in the protective plastic is messing up the polarization (done some reading )

Hmm. According to http://www.wikihow.com/Degauss-a-Computer-Monitor LCD screens can not be degaussed.

That's interesting. I've tried adjusting the screen settings, but it didn't improve. I'll try contacting support then. Thank you.

A tweaked version of Keith Merrows 5150. Cuts through the mix incredibly well (as the 5150/6505 is known for). To be honest, I can't understand why people use rectifiers, with their muffled, saggy sound

Thanks for your reply. Unfortunately I can't rack mount my lunchbox Strange that even new units have this. Maybe the kemper is vulnerable to normal shipping handling.

First of all, I love my new Kemper. Finally I have a tone rivalling my Peavey 6505 with some modified profiles and an FRFR. Will also be using this for fly-in gigs.
I bought the Kemper unseen second-hand (only used 10 hours) to save some money, and I noticed the display has a weird "moire/rainbow/wave" pattern. So I don't know if was like this from the factory. Do you guys think this is a small crack in the LCD itself? When the display is off, the wave-pattern seems to come from a tiny dark spot at the bottom. When I push on or below the screen it nearly goes away. It is a small annoyance since the Kemper is working fine, but somewhat irritating nonetheless. Should I live with it, or try to fix it?
