    hey. i have a guild "thunderbass" amp. i think it's about ten years old. i've had it here in my basement for about 4 months. this problem has only started happening a month and a half ago. in mostly any position of my bass i get this loud humming noise. i have to position it another way to stop it and it's really hard to play. i'm absolutely sure it's not my bass cause i got it checked out and there was absolutely nothing wrong with it. and it's not the cord cause i tried a whole buncha cords and it happens with all of them. i asked someone about it and he said it might be because i have a flourescent light across the room and it's interfering. is this the problem?

    try the amp in other rooms.

    When I lived with my parents I had a little combo that hummed. After various punch ups with the vendor who couldnt find the fault, my bedroom was on the same mains circuit as the kitchen and the refridgerator or something was interfering with it.

    BTW it might be the light, can you change it for a bulb affair?

    definitely check out the light. i cant play in my living room because we have these little flourescent bulbs that my parents put in the lamps, and i didnt know about them. i went to play one day, and all i got was a lot of 60 cycle hum. so turned off the lights, and it fixed the problem. all you have to do to figure out if it is the lights is turn them off. its that simple.
