Hi everyone. I have a problem with this wiring, I did the wiring attached with a conversion from the S-1 to a 4PDT has shown here from Phostenix' site. I went through this schematic about 6000 times. Did it all over again all weekend. the middle position with S-1 up (middle pickup only) is not working. No sound at all. S-1 down mode, middle position=Neck HB split + Bridge HB split, is working perfectly. I even took it to a guitar tech, told me that the schematic was made perfectly. Here you can see the schematic from Phostenix, the S-1 to 4PDT schematics, and a photo of the way I did it myself. Pickups are SUHR, normal Duncan colors. Can you please kindly assist me? I busted my head over this and I'm stuck for a few days. What's wrong with the schematic?

I can't tell much from the photo. Do you have a diagram of what you actually wired, with the conversion to the 4PDT switch?

I think I see a problem with your translation from the S-1 to the 4PDT. As per an article in Premier Guitar by Dirk Wacker, the S-1 switch logic is like this: Notice that he has numbered the center, common lugs 1,2,3 and 4. With the switch set so that 1 and 3 connect to the left, then 2 and 4 connect to the lower lugs. Your conversion diagram is the opposite- double check your numbers against this diagram and you'll see what I mean.

You mean the problem is the S-1 to 4PDT conversion by Phostenix which is the image I posted? Do you have an accurate conversion for this? I'm really sorry but I can't get my head around this...

If there's going to be a problem here, it'll be in the labeling of each of the four S1 sections. If one person calls "Section 1" as being directly under the three volume control terminals, and another person calls that "Section 2", then we might be in deep doo-doo.
The best way to remember the layout of the S1 is this: switch up (or 'out'), those terminals physically closest to what would ordinarily be the grounded lug of the volume control go to their respective commons. With the switch down (or pressed 'in'), the connected terminals are those farthest away from that same grounded lug.

You mean the problem is the S-1 to 4PDT conversion by Phostenix which is the image I posted? The S-1 to 4PDT conversion you posted is legit. It has the pot oriented in a different direction which misled Newey. I would suggest you redraw the diagram to include the 4PDT, then verify that your wiring matches exactly. Your photo isn't much use. Following a bundle of white wires is tough enough in person. Via that photo, it's nearly impossible. It's also possible the original wiring diagram has an error. Or that you have a defective switch (either the 4PDT or the superswitch).
