Does the buzz change when you touch the strings? If so maybe the ground to the bridge
isn't solid anymore.
Have you tried the same set-up in a different room (on a different circuit)?
I have a laptop power supply that kills radio signals in the bedroom, are
there any suspect power supplies on the same circuit?

I had a gig last night and didn't want to disassemble anything beforehand .... the gig went well and I kept it in the middle position the entire time. However, during the sound check I experimented a bit and found that the front pickup had some buzzing (at an acceptable level), but the rear pickup was absolutely HUMMING ..... LOUDLY !!! But it still had output of the notes played. This leads me to believe that possibly there is an internal break within the pickup itself, maybe on the negative terminus of the coil ? Would that cause a loud hum while still outputting notes played on the strings?
Craig, would microphonics cause such a thing? Is this a characteristic of when a pickup goes microphonic? I dread having to disassemble the pickup to find out without having some solid evidence that it might be the cause of this problem. Again, I'm getting a steady 5.xx ohm measurement from this pickup so I don't think the internal leads may be broken. However, if it can be pinpointed to microphonics then I'll put on the white lab coat and prepare for surgery.

(Addendum): A thought --- these pickups are reverse wound or reverse magnetized, yes? If so then that would explain why the middle position cancels the buzzing, but if the rear pickup is the reversed one then all my carefully crafted shielding has just become a great big giant antenna !!!
