    Dammit. Not a lot of hope then. It started maybe a couple months ago and nothing here has changed here. And whatever it may be in her place i can't do anything about that. She's not the type that is helpful or cares to be, so i guess my only fix is to run a long cable from the socket that sound quiet to where the amp is. That would be possible but hideous. Oh well...Damn....

      If an extension cord from the "good" outlet quiets the problem in the sam room where it was noisy before then it's definitely a faulty house ground on that end of the house.

        I see what you're saying. I didn't think of that. I assume you mean it could be the location and not the outlet due to EMF or something like that. No matter, as i can't easily run a cable along the route without looking horrible and being in the way anyway.

          I find it hard to imagine what could be wrong with the electric wiring.
          My take is something is being injected into the wiring.
          Like a dimmer switch circuit.
          It could be your neighbor that is the fault.
          Couldn't hurt to have a nice 'over the fence' chat.

            trust me, you don't know her....it COULD hurt.

              Seriously, get a ground lift adapter. Connect a length of wire to it's ground lug. Connect that to a cold water pipe with a clip lead. No buzz? Got to be copper or steel pipe and a clean connection.

                  I did that yesterday, but i didn't have a adapter so i just did it anyways ans made the contact to a cable ground to see what happens and it just got louder. So i assumed the ground is good because that apparently created loop. The pipe i assume is a cold water pipe. Don't know what els it could have been and if it wasn't it wouldn't have caused a loop.

                    The point is that there may be something undesireable floating on your wall plug ground connection. That's why you need to use a ground lift adapter to isolate your amp from the wall plug ground. Then use the tab on the ground lift adapter to attach a proper ground. Like your homes plumbing.

                      Ok. I'll get an adapter today and post with results later.

                        I am looking forward to the test results.
                        I am not at all convinced it is a house 'ground' issue.
                        (Although it very well could be. A certified electrician I am not.)
                        After all the green wire is attached to the white wire at the fuse panel.
                        The green wire is for safety issues.
                        Not grounding, hum issues.
                        I would try to see if it is a daytime nightime issue.
                        If nightime, that spells Triac light Dimmer somewhere.

                          Are you saying that on your fuse panel the green plug leads are directly connected to your nuetral!?! That's not right. I'm not an electrician either. But that's not right. For one thing, why have both branches in that case. Just connect the wall plug center prong to the nuetral lead on installation. I'm certain I've seen the green lead on fuse panels connected to the metal box chassis and from there to a ground spike or plumbing. There may be some three phase well pump circuits or some such that float the green lead to the panel. I'm not familiar with it. But I do believe that a wall plug center prong is grounded. As in attached to a large, conductive metal mass burried in the ground.

                            Here is a quote:
                            "Besides black, red, and white wires, the cables in homes wired since the 1960's also contain a bare or green ground(ing) wire. Like the neutral, it is ultimately connected to the tranformer's grounded terminal, but this wire is not connected so as to be part of the normal path of flow around the circuit. Instead, it is there to connect to the metal parts of lights and appliances, so that a path is provided "to ground" if a hot wire should contact such parts; otherwise you or I could be the best available path. In other words, when a ground wire does carry current, it is taking care of an otherwise dangerous situation; in fact, it usually carries so much flow suddenly, that it causes the breaker of the circuit to trip, thereby also alerting us that a problem needs attention."

                            Additionally, I had to replace a breaker a while back & I looked.
                            They are indeed connected.

                                Daz et al,
                                Back in post #11 you verified that the buzz completely goes away when you turn the Guitar volume control down to zero. To me that means that the interference is being picked up by the guitar pickups / wiring harness and not through the mains wiring. Therefore, you need to find what has changed that is radiating the signal that is being picked up by the guitar and the work you are doing related to the AC line wiring is barking up the wrong tree.
                                HTH,
                                Tom
