A Public Service Announcement
Gibson neck and bridge four conductor humbuckers, wired traditionally, with solder, and to be used only as humbuckers without any phase switching or coil cutting, has long had the same wiring color scheme as one another.
When Gibson began to use printed circuit boards (PCBs) in many guitars like the Les Paul and the SG, at least since 2011 or so, there's a confusing difference in the bridge pickup's coils magnetic polarity and in the wiring color scheme WHEN WANTING TO WIRE IN OUT OF PHASE SWITCHING AND COIL SPITTING.
I have evaluated several different four conductor quick connect pairs of Gibson humbucker pickups and found the same wiring changes in all the bridge pickups.
I created the following picture and am posting it here in case others out there take a four conductor Gibson humbucker from the quick connect era and want to cut off the connector and wire it in WITH either an out of phase switching scheme and/or wiring in switches for coil splitting.
The several sets of four conductor quick connect neck/bridge pairs of Gibson humbucker pickups I've had all had these exact details, and I checked each set several times to be sure of what I was seeing.
I am including my email address too in case someone sees a problem in my drawing. I welcome corrections.
