Pickup Wiring:

All single coils and split coils – the black wire is ground and the white wire is hot. The gray wire also goes to ground unless a buffered input preamp is used like an Audere, in which case the black wire goes into the preamp common and the gray wire goes to ground.

All dual coils and humbuckers except Music Man replacement – for series: black = hot, green plus bare = ground, red and white together and taped off. For parallel: black and red = hot, green, white, and bare = ground. Black and white are the bridge coil and red and green are the neck coil.

All stack pickups – the white is hot, the black is ground, and the red is the tap. This means to run the pickup in single coil mode you need to short the red wire to ground and this can be done easily with a switch. For normal hum cancelling mode just leave the red wire taped off and not connected to anything. If there is a gray wire, see below. Here’s a diagram for switching the stacks to single coil mode.

Where does the gray wire go? The gray wire is for grounding the pole pieces. In an installation with a buffered preamp (Audere) where the common out on the pickup needs to be separate from the system ground the gray wire will be ultimately connected to the sleeve on the jack. This can happen by connecting it to shielding foil, the bridge ground point, or the appropriate connection on the preamp. On a non buffered preamp, which is pretty much everything else, or a passive installation, the gray wire can simply be tied into the black wire and connected exactly where the black wire is connected.

Basic 3B Basic module with pots

Kitchen Sink 3B installation. This shows the preamp with all the bells and whistles including an active passive push pull on the volume and 2 mid frequencies on a push pull. It also has the chart of the mid frequency capacitors and shows how to set up any 2 frequencies you may want on the switch. We do not sell the preamp prewired in this manner, but for those who want to have all the options we offer this diagram.
