I have taken the my pedal board out of the equation for this issue. My signal chain is as follows. Suhr modern running into Friedman small box. I have the 8 ohm tap going into a suhr reactive load ir and i am monitoring through headphones.
I have the amp cranked and I am getting a ton of hum. The hum goes away when i touch anything metal on my guitar or on the reactive load. I never had this issue before. I noticed it when I plugged my eqd erupter in and it made a crazy hum sound when I turned it on. It stopped once i touched the instrument cable jack. I have gone through my guitar and done continuity tests with a multi meter. The only thing that gives me a different reading from all the other test points is the 5 way switch. Some of the readings look like the pickups resistance. Parts of the switch give me a different reading all together instead of all 0's. I have also done continuity checks on all of my cables and have even swapped power cables and instruments cables when checking for issues. I have also tapped all of my tubes to see if anything is micro-phonic. No issues with the tubes that I am aware of.
I also plugged my guitar into my boss katana and I did not get any of the humming or the grounding issues with the guitar. I did not have it hooked up to my reactive load IR either. I also plugged my guitar into my smallbox and went through my speaker cab. The amp seems to make more idle noise than I remember when I have the volume all the way up on my guitar when I am not playing. But it could also be the room itself. I honestly can't remember. I have also switch power outlets in my house. Everything is using 3 prong outlets so i would assume everything is grounded. Like i said I did not have the issue before.
Not sure where to go from here. Part of me feels like my 5 way switch has come underground but I am not sure how to check. My amp sounds fine so I am worried that something has become underground in the suhr reactive load IR.
