| I'm at a gig this morning, just hooked everything up, Show Pro, Goodrich 120 & original 68 Fender Twin. The pot in my Goodrich 120 wasn't scratchy 2 days ago but it is now. Thank goodness, I have my Hilton in my seat....hooked it up, I've got a slight hum. Could it be a ground loop problem or is it just my single coil pickup being amplified w/the Hilton pedal? I switched back to the Goodrich just to check, hum gone, but pot still scratchy. This gig is being recorded, suggestions & advice appreciated. |

Found a solution, plugged in to different receptacle (after frantically searching & plugging in to about 20 or more of them) on other side of stage, hum gone. I've been meaning to purchase a Hum X and a high quality power conditioner.  |

A long time ago, during a former incarnation, I was asked to try and solve a 60HZ interference on a piece of 120v equipment. It was a standard 120v/15A circuit. I found that there was a small potential between the neutral and ground conductors. This small potential is caused by normal circuit loading since current through a wire results in a small voltage drop, a loaded circuit will show a small potential between neutral and ground. Since the ground and neutral are bonded(joined) at the panel, that small PED will not be dealt with before the neutral conductor reaches the panel. The possible reason that you cured your hum be changing outlets may be because you changed to a circuit with less load or you moved to an outlet nearer the far end of the circuit (less neutral current). How does neutral current and PED between neutral and ground cause a hum. I don't have a theory for that, just know what I found. BTW, I cured the interference on the job I was called to by bonding the neutral to the ground at the outlet where the equipment was plugged it. We returned later to run conduit for a dedicated outlet for this equipment to solve it permanently.
