    Oops, the misunderstanding is on my part. My apologies I missed that the pickup you want to you use for the middle position has 2 coils. That also explains my mistake in thinking what the Series-Parallel switch was supposed to do.

    I will go back and make the updates. What you actually want isn't as difficult to accomplish as what I just figured out - (haha!). The one part I am not sure about, is if the Series-Parallel "In series" setting for the Middle Pickup can be bypassed when the pickup selector switch is in Positions 2 and 4. We will see.

    So as far as replacement hardware is concerned: you still need to replace the standard 5 way with a superswitch, but you probably no longer need to replace one of the 2DPT switches with a 3DPT on-on. Let me get through the new diagram to confirm that.

    BTW, if you did not already, please see my prior post about measuring your control cavity height before ordering a suoerswitch.
    This is great news, because the guy who does my wiring has a super switch that I can purchase from him. I just measured the cavity depth in the Carvin, and it should be able to accommodate either switch.

    One question- you mentioned the Series-Parallel "In series" setting for the Middle Pickup being bypassed when the pickup selector switch is in Position 2 and 4. Just wondering- why would it have to be bypassed? My goal would be this (for example):

    (All below with coil split off, "toggle switch 3" being Series/Parallel switch)

    Position 2 (toggle switch 3 set to "Parallel"): Bridge Humbucker full, in Parallel with Middle rails; Middle rails in Parallel with itself
    Position 2 (toggle switch 3 set to "Series"): Bridge Humbucker full, in Parallel with Middle rails; Middle rails in Series with itself
    Position 4 (toggle switch 3 set to "Parallel"): Neck Humbucker full, in Parallel with Middle rails; Middle rails in Parallel with itself
    Position 4 (toggle switch 3 set to "Series"): Neck Humbucker full, in Parallel with Middle rails; Middle rails in Series with itself

    My understanding is that these all would be hum-cancelling. However, any of the above positions, I would assume, when the humbuckers are split, would not be hum-cancelling

    I was anticipating putting the middle rails pickup in series with itself when active with another full humbucker, but in parallel with itself when active with a split humbucker, to try to match outputs a little closer.

    Thanks for your patience with the descriptions from a novice-level electronics understanding!

      Thanks, I follow you.

      Let me throw this idea out there. To try to have at least some of Position 2 and Positon 4 that are hum-canceling when the 2 humbuckers are split, what do you think of the idea of also splitting the middle pickup whenever the 2 humbuckers are split?

        I think it's a great idea- however, I've actually read a lot about this pickup, and there is a lot of feedback that it sounds very weak/feeble when split. Honestly, I think I'll be OK with the hum in position 2/4 (when 'buckers are split)

          Ok. I will begin working on the revised diagram.

            *if* that is your end goal (i.e. middle pickup In Parallel *only* when the humbuckers are split, and the middle pickup In Series *only* when the 2 humbuckers are not split), then are you aware that with a 4PDT switch you could accomplish both things with a single switch action vs your current plan where you have to flip 2 switches each time? Are you interested in doing this via just 1 switch?

              I had no idea that was possible- and is probably something I might want to try in the future! But I figure, since the guitar does already have 3 switches, I can use this to play around with different configurations (split w/ series or parallel middle, humbucker w/ series or parallel middle).

              I've never actually heard the middle in parallel with split humbuckers... so I'm just making an educated guess that it'll sound the way I like. I might want to try everything out before making a permanent decision.

                Ok, for now, separate switches.

                  Amazing stuff. Never been so excited for a pickup installation. Should be ready later this week- will report back!

                    Eric,

                    I spotted something that needed to be changed. Use this version instead.
