Multiple Internal Server Error issues... Due to finding out our house has a dirty electricity issue! The problem: Getting nasty buzzing sounds through my amp (Kemper and Kemper Cabinet) from the room I've converted to my office. I believe the noise is EMI/EMF from dirty power. I'm using a Furman SS 6B power strip with some minor filtering, PRS / Van Damme instrument and speaker cables. I'm wondering if I need more filtering, like a Satic whole house filter or an upgraded power conditioner/filter. Anyone run into this issue? I know it is not a ground loop issue, since touching the strings on the guitar doesn't make the noise go away. Plus the Kemper has ground lifts which had zero impact. The Furman is supposed to mitigate 60 cycle hum as well. I do have some challenging issues with the room - the other side on one wall is our refrigerator and the back wall is shared with the garage where the main electric panel, central vacuum and sprinkler control boards are located on the shared wall. While my Kemper noise gate will 'solve' this issue, I have to have the gate on max which kills dynamics. I'm trying to solve the problem so I can roll back the gate to a more reasonable level. Only using H9 in the effects loop. All my guitars are humbuckers and all equally pick up this noise (which of course is worse when flipping to coil tap mode). Only when I flip to the piezo does the noise stop, since that isn't a magnetic pickup.
