    Hi all,

    I'm stumped. I bought a CTS 250k push pull pot for my Jazz Bass, but can't find a decent diagram to wire it for series / parallel. The diagram that came with it seems to be for a humbucker being put into series / parallel, I say this is as to me it isn't clear where the wires from the other pots go...

    Edit - It's a 2015 USA Std Jazz Bass, so black and white wires with regular VVT

    The pot and diagram is in the link below, any help is very much appreciated.

    Thanks!

    The diagram is for series / parallel switching between two halves of a humbucker. The same approach can be used for two separate single coils, but the wires don't come together in a bundle as depicted. They really ought to label the colors in the diagram key though - I'm assuming green and black are the two grounds and red and white the two hots. Looks like green and white are one coil (or pickup) and red and black the other. What colors are your pickup leads? For reference, so nobody else has to go to the ebay page, here's the pic:

    And the + line coming out the right is the one that goes to the volume pot then tone pot then output jack.

    What are your existing controls? If there are two volumes or a volume and a blend, then those have to go before the switch rather than after.

    Thanks for the pics and replies, really appreciated.

    (I may have to go offline soon, but will be straight back on in the morning)

    Thanks again

    This might help:

    If you remap that using the "normal layout to our layout" diagram above, you should have what you need. Be aware that in series mode, there'll only be one working volume controlling both (possible to keep them separate, I think, by putting the volumes before the switch, but it's a whole lot more work). Edit: Scratch that last parenthetical about separate volumes in series, wouldn't work as desired (one volume would control one of the pickups, but the other would control both together, still maybe useful but not very intuitive to use at all).

    I used that same diagram on my Mike Lull PJ4 recently when I used a toggle switch, it worked great. I was thinking about trying a straight copy. But....

    I was wondering about copying it, but the terminal codes wouldn't match up to the first diagram pic I posted. (I.e. Terminals 1&3 are linked on the old school one but it's C1&3 on the CTS). I could take a guess and 'translate' where they go, (so put 1&3 to C1&3) but if I get it the wrong way around (2&4 to C1&3 as the diagram below has no codes) then push might be Series and up Parallel, not what I want. Or it may not work at all????? Am I missing something here? I'm happy to do this but understanding electrics is not a strong point.
