Connect to ground
If you are experiencing unusual handling noises, sometimes the pickup will function best without the shield
connected to ground, but Black or red lead must ALWAYS connect to ground.
Ground lead is soldered to shield at factory- peel back some insulation to reveal it
Solder all grounds at the same location- Back of Volume pot is best.
For Pro Tubes- MIDDLE PICKUP- RED=+, White=Ground
Solder all grounds at the same location- Back of Volume pot is best.
In single coil mode Neck Humbucker uses ONLY Neck-side Coil,
Bridge Humbucker uses only Bridge-side coil. To reverse these short
red-white pair to + instead of ground.
When wiring to existing pickups- If in-between position is too thin you are out-of-phase. Just reverse the +
and ground leads on the GFS pickup without disturbing the silver shield. On Tele Bridge pickups the baseplate
ground lead must also be reversed. GFS Humbuckers may also be wired using Seymour Duncan wiring codes.
