i apologize if this has been covered numerous times. i have a history of not being able to use the talkbass search function effectively. my amp seems to have a loud hum that goes away only when i hit the mute button on the amp. since it doesn't happen anywhere else, i believe it to be the outlet i'm plugged into at practice. is there anyway to put something between the plug and outlet to eliminate this? i always assumed electricity was delivered by magical fairies and it scares me. i am no electrician, please use laymen's terms! mods, please move this if it is in the wrong forum.
