If you happen to be in front of a TV or CRT monitor, that'll do it, too.
actually it was a death metal pedal through an 70's Ampeg Tube bass amp. when it was on clean there was no noise at all, just when i had the distortion on. like i said, when i turned the tone all the way down there was no noise. i even tried leaving the room and there was still some buzzing (if that helps) i just texted my cuz to see if he's getting any noise with his Epi les paul.
and to you and everyone else, thanks for the help
