H-9 making high pitched siren squeal

[RC2]

1.  

   1. I've got both an H-9 and H-9 core that I've been running in the Loop of my RedPlate BlackVerb amp. They've both worked flawlessly sense I bought them both new last month but today when I turned on my amp the Regular H-9 just went in to an extremely loud hight pitched pulsating squeal that sounded like my amp was blasting off. I've check all my settings and they're the same as they've always been and my H-9 Core is still working perfectly in the loop.
   2. Any suggestion on what else to check or what could have possibly change with my Regular H-9 will be greatly appreciated.

Hard to know at this point. Some algs have a feedback control that can be noisy if it is turned too high.

If it is not that, try different presets.

If no help, try RESTORING FACTORY SYSTEM SETTINGS.

I've tried several preset and it's the same, this screech goes far beyond just noise. I'll try restoring the factory presets and see if that helps.

Thanks for the suggestions.

"RESTORING FACTORY SYSTEM SETTINGS" seems to have solved the problem.

Thanks again for the help Nick.
