| Hey Gary Glisson: As an Evans owner myself who has some trouble with hum, I'd like to know what the problem was that you got figured out! |

| I had low level hum problems with a new SE-200 (2004 model with the Delta Lite speaker) and I sent it back to the factory. The problem was the idle current for the power output transistors was too high. They readjusted the idle current and it took care of the low level hum. |

hi Brint. i narrowed it down to my volume pedal and the wiring in my house. but pertty sure its my volume pedal. i have a goodrich 10 K pedal when i have one amp plug into the pedal dosen't matter which amp no hum but as soon as i plug the second amp in i get hum in both amps there is a little hiss when you run your gain above 5 but the hiss is not hearable on my amps if you are standing 5 feet away. i did reduce the hum a little by getting my house wiring digram and using a large extension cord pluging one of the amps in to a outlet wired seprate from the outlet that my other amp is pluged in i'am gonna buy me a hilton pedal in the next couple of weeks
do you have a FET 500?
thanks gary |

If you are getting hum with two amps plugged in, it's the standard "ground loop hum" problem. You can use a commercial "hum elminator" on one amp, but you can verify that by ungrounding one amp (one amp only).
It's not the volume pedal that's causing it. |

| I agree with Jack. Sounds like a classic case of ground loop. Make sure each amp has a ground on the power cord. Try to plug everything into one wall socket. Make sure the wall socket is grounded. There still could be noise. |
