  • Schematic help

    Looking to install two new SD pups in my PRS, and need some help with wiring/switch selection!!

    Neck- TB-4 trembucker
    Bridge- Phat Cat

    Is there any way to use a LP style 3-way switch (perhaps a 6 pole version?) to have my options as:
    Neck (both coils) only
    Neck (single) and P90 in parallel
    P90 only

    looking for help as to how to wire this (and what the proper switch would be)

    thanks in advance!

      Welcome to the forum.

      Before buying parts and wiring, have you confirmed a Trembucker will fit in the neck of a PRS, and is a JB in the neck and Phat Cat in the bridge really what you want to do?

        Yes it fits just fine.
        And yes. While not typical, I had an old Explorer with this same pickup combination and it was killer (just different switching) and suits my needs/style very well
        (the pickup arrangement is also not all that different from an EBMM Valentine).

          You'll need this switch, or one similar: https://guitarelectronics.com/3-posi...switch-chrome/

          The next you'll need to figure out is which coil of the JB will hum-cancel with the Phat Cat. I'm not sure. Once you get the specific switch, we can go from there. One problem is that those switches come in two different contact configurations. One where the middle contacts switch together, and one where the contacts alternate. You need to know which you have before we can do a diagram.

          One other small issue is that those switches are hard to find with the taller bat handle that's typical of a Gibson guitar. They usually have a short handle that you may not like.

          Once you get the switch, the diagram is fairly simple.

            Here are the two switch configurations you'll run into. We would need to know which you have before we could do a diagram.

                I’m hoping to wire this up later this week…just had my gallbladder removed so this seems like a good “stationary activity” lol

                any further guidance would be greatly appreciated.

                  For the next step, you'll need a meter. (DMM) Since the switch isn't symmetrical, you need to establish a top & bottom. Put the handle in the middle, (pos. 2), and using ohms, meter either the "B" or "C" terminal so that they match the diagram. In other words, contacts down. Now, using a Sharpie, or somesuch, put an "X", or write "top" where the red arrow is. Now you'll know how to orient the switch for the diagram.

                  I've got some errands to run today, so I can draw up the diagram later this evening or tomorrow.

                    With the switch oriented so red arrow is "up", make connections as so. I'm not sure which coil will be humbucking with the Phat Cat, so try the blue jumper (blue for illustration only) to ground first. If that isn't humbucking when both pups are on, just move it to the terminal with the green arrow.

                            Hey Artie - it’s been a while. I’ve changed plans ever so slightly ‍♂️

                            So I am actually going with the “traditional 3-way toggle” in this guitar and want to replace the 5-way rotary in my other CE22 with this switch…essentially what I want is a toggle to switch between positions 10 (bridge), 9 (outer coils in parallel), and 6 (neck) of the rotary.

                            also - if you care to further share your genius…I want to rehome the 5-way rotary into the Swamp Ash Special I just picked up. Looking to have a 2-way ON/ON toggle that switches between “les Paul” (bridge humbucker) and “strat” (split neck and bridge pups and uses 5-way rotary for the typical strat options)

                              That's not exactly "slightly."

                              Let me revisit this and make sure I understand.
