    Hey all,

    I recently got a Tune bass that I had left with a friend for 15 years! Anyway, it plays beautifully, but the internal preamp has some pops and cracks and I am thinking of replacing it with something like an Audere classic.

    Opening the cavity, I see that each pickup has 5 wires. The braided one is obviously the shielding and the red an white ones are connected to the preamp.
    There are two other ones, a green and a black that are soldered together. Would any of you guys know what these are for?

    Thanks for the help! 20181117_095125.
  2. Those pickups are humbuckers & the green & black are the connection to make the two coils of the humbucker function in series:


    This^ is just an example & none of the brands in the diagram match up.

    If you want to know which wires connect to the other sides of green & black, you'd need to disconnect green from black & then measure the resistance (Ohms Ω) between those leads & white & red.

    This ^

    Having the 4 conductors (two for each of the two coils in each pickup) gives the option of running the coils series/parallel, or splitting the coils (isolating one) so the pickup is a single coil.
