Hello everyone! I’m new here but I was wondering if I could get tips from anyone who has gotten this issue before.

I just moved into a new house where the electrical outlets in my music room are not grounded. I have a lot of hum noises going through my guitar amp (even when nothing is plugged in) and also in my mic pre. I never had this issue before in my other recording spaces. I have everything plugged in my Furman M8X, still I get a lot of electrical noises. Seems like a pretty low in frequencies noise. (60-100hz)

Is there anything I can do or buy to make it better?

Thanks in advance for your advices!
