Pickup swap w/buzz is NOT pickup swapping drunk
Looking for possible reasons for the buzz after a pickup swap, can you help?
So my buddy is unhappy with the sound that his bridge pickup puts out, and I offer to do the swap-out mod.
He shows up with a 2003 Korean Schecter contour-top with a Duncan Designed H-H config, with 1 Pull/Push pot, 1 reg pot, and a 3-way toggle.
I suggest a hotter Ibanez INF4 for the swap.
Wires look the same on both and I see that there are 3 joints to de-solder/re-solder- a single to one side of the 3-way, a twisted pair and a ground to the Push/Pull pot.
I swap all 3 from the D.D. and replace with the same 3 from the INF4, then check to see that it is right before closing it up. Seems good so far, I close it up, tune it, plug it in.
Toggle up & Pull the pot- Neck pickup still sounds the same as it did- check!
Push the pot- ditto- check!
Toggle to middle, pull, push, both pickups working, bit of extra buzz/60cycle hum present. -check!
Toggle down, pull, push, INF4 pickup working, noticeable extra buzz/60cycle hum present. -check!
Remove rear cover and note all connections made, but when I touch the metal on the 3-way at the INF4 side of the 3-way, the buzz ceases.
Loaned him one of my RG's for the time being and told him to check back w/me tomorrow.
Cold solder joint on the 3-way switch?
I will try de/re soldering the small single wire on the 3-way in just a few minutes from now, maybe that will fix it.
If it doesn't, ANY IDEAS on what it could be?
On a side note, could there be an "imbalance" between these pickups that should cause any poor operation or merit re-selection of a different bridge pickup altogether??
Thanx in advance for any pointers and info.

Reason: added temporary guitar solution of a loaner axe.
