Freqbox Whine

Anybody get this when their 107 is on at all, even with the Mix down all the way? I do. It is not usually an audible problem because the MF-101 removes it from the spectrum. Just curious.

How’s it being powered? Any difference with another wallwart?

I will try that, currently it is being powered off of a Voodo Labs Pedal Power 2 multi outlet device. It does seem to be only the Freq Box. When I turn it off the whine goes aways. I will tinker with the effect of using a wallwart…Thanks.
