Need electrical hum sound

[joker]

I'm looking for an electrical type sound effect for my effect box that I'm using to light the hall in my haunted house. It works fine as is turned up, but I want to avoid screams/sounds from effecting the lighting.

Any suggestions?

Does your effects box have a audio jack input?
You could use an audio program like Audacity (Free!) to create a 60 HZ sound file and feed that into your effects box.

Sweet thanks. I may have to add some effects/variations to get the needed change but that should work great.
