5-wire HB wiring into bridge position

    I have an EB-0 where I'm adding a cheap MM-style humbucker into bridge position. Trying to do essentially jazz bass with blend -wiring.


    However, I have no idea how to wire the HB. It has 5 wires, where red+white are soldered together, green+bare are soldered together, and black is separate.

    Do I think this correctly that it's now wired in parallel, and I should treat (red+white) as hot and (green+bare)+black as ground?

    Black + (white+red) says 5,7k
    Black + (green+bare) says 10,9k
    (white+red) + (green+bare) says 5,2k
  2. That sounds like series which is how most humbuckers are going to be wired for the “traditional” set up. If you don’t want to do any switching then black is hot and green and bare are ground. Tape or shrink tube the red and white.

    Thanks, I was thinking series wiring would make more sense.

    Can anyone explain me why are there 5 wires instead of 4, by the way?
  4. The bare wire is a separate ground. That way you can do some wiring without having to worry about one of the wires being connected to any other part of the pickup besides the coils.
