Hey guys I don't know if this is in the right section or not.....


I've had a problem with my jazz bass for a while now, and was wondering if you could help me out.

Basically it sounds as if its not earthed properly when i have the tone pot turned up. Even when I have both volumes turned all the way down, if the tones turned up, theres an almighty hum :/

I've attached a recording from my iphone. Apologies for the quality, but it shows the problem. Its an extreme hum, which is doing my head in, its not healthly!!!! I'm not sure whether its a dodgy pot, or whether its a earth problem....

cheers guys
