OT - Will EB Tech HumX fix "buzz when not touching strings"

[Resonant Alien]

I've the old buzz when not touching my strings/jack problem (even with humbuckers). I seem to remember some of you guys mentioning the EB Tech HumX. Will this help this particular problem?

I'd be looking more at why that outlet isn't grounded properly. Sounds like you have an open ground somewhere in your circuit.
I doubt the HumX will fix that, but ya never know with grounding issues.

Thanks. I had this problem before, and I always assumed it was a problem either with the house ground or the guitar ground, but I did some more research last night and it's not really a grounding problem. It's an EMI/RFI problem, and looks like I need to try shielding the control cavities with some copper tape or shielding paint. What I read was that if it were an improper ground, it would actually get worse when touching the guitar, rather than getting better. Makes sense once I read it - in this case, it's not that your body is grounding the guitar when you touch it (if you're standing on carpet, you body is not grounded anyway, so it can't possibly act as a path to ground), your body is acting like a huge shield/antenna in reverse, providing a path for the EMI/RFI to be dissipated. Seems the trick is to shield the electronics better to keep the EMI/RFI from getting there in the first place.
