I find that my Stage is noisier than my rack, which is completely silent.
When I touch the browse knobs it does a ground loop sound (not too important because I don't record touching them at the same time )
But I also found that the Stage produces a lot more "white noise" than the regular Kemper, especially at hi gain settings.
I tried the ground lift option, different guitars, power supplies, sockets...
Thoughts everyone ?
Live I think (didn't bring my new toy at rehersals yet) it will not be a problem but for recording purposes I find it annoying.
