    Default Confirming wiring diagram for PRS SE Custom 24

    Hey guys,
    Can you please confirm my wiring diagram?

    I'm upgrading my PRS SE Custom 24 with electronics (CTS pots, Orange Drop caps, and 3-way Oak Grigsby blade switch, Switchcraft output jack, and vintage pushback cloth wire). As you know, the CTS Push-pull DPDT pots lay out their solder terminals a little differently than the ones shown in the Seymour Duncan. I'm also not a huge fan of piling a bunch of wires onto the back of the pots. So, I created this wiring diagram. Is it correct? Thanks in advance for your confirmation. Much appreciated.

    Robert

    Okay... after looking at my wiring diagram some more, I realized two things:
    1) I can't really solder anything to the top of the tone pot, because it's all plastic. Duh. Embarrassing.
    2) The legs of the tone cap can't easily reach around to the side of the tone pot for grounding.
    So, I updated the drawing.
    I noticed I don't have a grounding wire running from the tone pot casing to the other grounding wires. Is this needed? Or does the wire running from lug 2 of the tone pot, into the cap, and then into the mess of grounding wires cover it?
    Thanks,
    Robert

    Looking at the amended diagram you seem to have the tone cap connected to both lugs 2 and 3. Was this intentional and what is the purpose /theory behind it? I have not seen this before .Otherwise, providing the cap is connected to ground the tone control should work. I do not think not having the tone pot itself grounded is detrimental but I would normally do so. I have had no experience with the CTS push pull but from what I have read the inference is that they can and should be grounded, so presumably it is possible.

    Out of interest, did you have any problems with the stock electrics? The SE Custom's play well and seem to be pretty trouble free.

    Thanks for your reply, GString.
    The tone cap will be connected only to the second lug of the tone pot. It’s just a quirk of the diagram. I’ll also run a wire from the tone pot casing into the mess of ground wires. Below is the updating diagram.
    No, I didn’t have any specific problems with the SE electronics. I just wanted to upgrade them to high quality USA parts.

    Putting the circuit ground wires together is something I do quite a bit especially if I am wiring up a combined Out of Phase/Series Push Pull. It simplifies the wiring.. This mod actually works well on the SE 24 with the coil cut mod. . Because of the way PRS pups are wired you are a bit limited with mods as you can't do parallel or coil swap.
