I was adjusting the height of my pups on a MIM Nashville tele and it seems that after I worked on the bridge pup I started to get a noticable buzz (hum) that was not there prior.
I did unplug the guitar and check...(it's not the amp)

Did you move the pup closer or farther away from the strings? If you moved it closer, you will get more hum, more volume, less sustain because the magnetic field has more impact on the strings. If you moved it farther away and got more hum, you might have upset a ground wire connection somewhere. Does the buzzing go away when you touch metal on the guitar or the strings?

yep, it goes away when I touch any metal part of the guitar and I did move it further away (lowered)...
So I might have broken a ground wire?

not necessarily broken one, but maybe disturbed a solder joint or something... 60 cycle hum is normal for single coil pups, and the fact that the sound goes away when you touch metal means the ground is working, tho it may not be working the greatest. My next step would be to remove the bridge and control plate and check the grounds. I would also add a bridge ground if one is not present. Bare wires under the bridge, solder the other end to the back of the volume pot. If your bridge pup has the plastic bottom and not the brass plate, you might consider shielding the pickup cavity too while it's opened up. All these things will help reduce the hum.
