It's something with my house. I'm picking up something! POOP.
Have you tried different areas of the house? Is there a rheostat (light
dimmer) in use when you get the noise? Are you near electric
appliances: Refrigerator, furnace/boiler, water heater, hot water circulation pump, etc?
Do you get the noise with no guitar plugged in? With the guitar volume turned down?
Does the noise change, increase, decrease if you point your guitar in different directions or up/down?
