I saw an old thread from 2010 on this forum, but the bot told me it was too old to reply to...
I have a considerable amount of audible noise (60cyc likely) being picked up by my electric guitar. The noise (hum) is very directional and location specific. The noise is not on the amp when the guitar is not plugged in. This tells me the noise is environmental and being picked up by my pickups... so i'm on a mission to find the source(s) of this environmental noise. I tested my outlets with one of those tester things and they look OK, but on a scope, I see a significant waveform between earth ground and Neutral. Could this cause the EMI/RFI I'm picking up?
Please see the video of my scope trace here, it's short:

from another circuit in the house and effects of a light dimmer

And if you are super bored, but want to see a Electrical PSA from my 4 yr old about tamper proof outlets...

I know this is a Guitar issue, but the guitar people don't know that much about house AC ... maybe someone recognizes the wave?
