    Re: Is there a problem with this diagram?

    The tone control in this diagram is wired up so the wire coming from the volume pot ends up going through the capacitor and then to ground. This will have the effect of removing a significant amount of the treble frequencies present in the guitar signal. The wire coming from the volume pot and the capacitor should be on separate lugs of the tone control. EDIT: Also, *none* of the lugs on a tone control should be directly grounded like the first lug is here.

    Also, the pickup combinations that result in each of the 5 positions should be listed in the diagram, as they are not intuitive. Those pickup results are as follows:

    1. Bridge humbucker
    2. Bridge humbucker and Neck humbucker in parallel
    3. Neck humbucker
    4. Neck North coil in parallel with Bridge South coil
    5. Bridge South coil

      BTW: Thank you very much for doing this Mincer. This will be very helpful to many people that come to the Seymour Duncan website for wiring diagrams.

        - The splitcoil mode is advertised as being active in the up position of the bridge push-pull, but it is wired so that splitcoil mode is active in the down position.

        - The hot wire from each pickup (black) is wired to the wrong volume control (bridge pup is wired to the Neck volume control, and vice versa).

        - the Neck volume push-pull control is described as the "tone" push-pull in a few spots in the labeling.

        - the label at the very top that is intended to state that the Neck push-pull is active only when the Bridge push-pull is up, is missing "Bridge" specifier. It just says "volume push-pull". Both push-pulls are volume controls, so the specifier is needed.

          The bare wire in this diagram should go straight to ground. It should not be coupled with the green wire and have the option via the phase reversal switch of becoming part of the Hot Signal. That would add unncessary noise to the output signal.

            Same kind of issue in this diagram as in the prior post: The bare wire in this diagram should go straight to ground. It should not be coupled with the green wire and have the option via the phase reversal switch of becoming part of the Hot Signal. That would add unncessary noise to the output signal.

              The top right lug on the push-pull of the tone control needs to be connected to ground. Without that connection, when the switch is put in the up position, the Neck humbucker does not go into splitcoil mode like is intended.

                The potentiometer and the capacitor of the tone control are not connected to anything. The potentiometer's right leg needs to be connected to the output jack, and the middle lug needs to be connected to one leg of the capacitor, and then the other leg of the capacitor needs to be connected to ground.

                  The finish wire pair of the Bridge pickup is hard-wired to ground via the lower-left lug of the bridge volume push-pull switch. This will lock the Bridge pickup into splitcoil mode regardless of whether the push-pull switch is up or down. EDIT: Also, when that coilsplit switch is in the up position, the Neck pickup's output will get killed/turned off when the phase reversal switch is set for *not* out-of-phase, because in that case both the black wire (North start) and green wire (south start) are being routed to ground.

                  It seems the intent is to make the bridge pickup's South coil the active coil when in splitcoil mode by shunting the finish wire pair to the hot signal via connection to the black wire, so to do that, the connection of the lower left lug on the bridge volume control push-pull switch to ground should be removed.

                  EDIT: also the phase control switch on the bridge tone control is wired so that the bridge pickup is out of phase in the down position instead of the up position.

                    Wow Jack, you're really going to town on this. Good eye for catching those.

                    Dave, thanks for doing this. It will be great info to have, but most importantly to be most useful, you can get those diagrams corrected.

                      Thanks GuitarDoc! It's great to hear that other forum members also see the potential benefits of this effort for both forum members and visitors to the SD website.

                      Since you are an esteemed wiring expert, and Artie seems to have been out-of-pocket lately (hope he is ok), would you mind reviewing the two diagrams in Reply #11 and Reply #12 of this thread that I was asking him to take a look at?

                        The push-pull on the Bridge pickup volume control should have the Black Wire routed to the volume potentiometer left lug instead of the green wire. And the green wire should be wired to Ground. As it is now, the Bridge pickup is wired Out Of Phase.

                        So the push-pull on the bridge volume pot should be wired just like the push-pull on the neck volume pot.

                            The phase reversal switch on the tone control is wired so that the Bridge pickup is out of phase in the down position of the switch, instead of the up position. The fix is to swap places of the green and black wires from the bridge pickup on that switch.

                              The phase reversal push-pull switch on the tone control is missing a connection to ground. The result will be a lot of noise coming from the bridge pickup. The fix is to connect the top right lug of that push-pull switch to ground.

                              Also, which coil of the bridge pickup that is active during coilsplit mode will fluctuate depending on whether the phase reversal switch is up or down, because of how the phase reversal switch is currently connected to the coilsplit switch. Additionally, Position 2 will not be hum-canceling in coilsplit mode because both North coils will be selected (same magnetic polarity) when the phase reversal switch is set to normal phase for the bridge pickup. This seems like a missed opportunity to have hum-canceling in Position 2. The fix for both issues is to connect the wire coming from the coilsplit push-pull switch to either the top left lug or the bottom right lug of the phase-reversal switch instead of the middle left lug.
