I have an issue with excessive hum and the jtv59. I'm running guitar via VDI cable into a HD500. I'm using the magnetic pickups and the modelling at the same time and using a panner to switch between them. For example: Acoustic jmodels and panning into a heavy magnetic-based tone. I'm running XLR right out to a EV monitor on stage and XLR left out to board. I'm getting a horrible hum now. It has happened before but seems to have gotten worse. I switched inputs in the presets in the pod to just the variax (right before the gig in a panic) and the buzz is gone.
Trying to brainstorm causes and solutions. The hum sounds like a typical ground loop. I've tried the ground lift on the pod and it seems to have no effect. This venue has bad power (as does a lot of places we play). Getting a few furman SS-6B filtering power strips that may help. I could just run to the board and the send guitar back to wedge.
Thought about getting the pyle PHE400.

Thought that is maybe a grounding issue in the JTV. If this was a normal guitar, I would gut it and foil and ground the pickup cavity. I'm a little hesitant to dig into it but will likely crack it open soon and take a look. I saw the pickup diagram that is flowing around.
Afterthought: I don't know if switching to the magnetics would bring hum back. That would be a great test.
Any help would be most appreciated.
