great post! I just bought a HW1 2006 fender jazz, has some unknown 10 pole pups that sound great, had a custom wire job from what I can tell. 2 vol one for each pup and a tone. Should be blend, vl then tone right? And when the vols are in diffrent positions i get crazy hum at home, not at the store..... maybe need to check the ground in the outlet?
Do you have fluorescent lights at home? Or is the microwave going all day long? Or are you standing an inch away from your amp? Any of the above can cause hum. As can dubious grounding in the house electrical system. One location I play in a lot has fluorescent lights and the power outlets are 2-prong, not 3-prong. Before shielding the noise from my bass was really bad, even WITH humbuckers. After shielding it is silent.
