Hi, I'm new and took long time reading questions and answers but I didn't found answer to my question.
I have noise in any outlet in my house and I suspect this is coming from a faulty earth ground since everything seem OK in all outlet and main breaker box.
Exemple: If I connect an amplifier for an electric guitar I get a ripple noise that sound like 60hz Bzzzzzzzz and this in any house outlet. If I go elsewhere the same amp is dead quiet.
Do I'm correct to think the house earth ground is faulty and should be checked?
Thanks
