Hello,

Since I managed to break the original switch, and that it would take over a month to order a replacement switch, I went for a DiMarzio EP1112 which seems like a good alternative.

I made sure that I soldered everything exactly like this wiring diagram:
http://www.dimarzio.com/media/diagrams/E.pdf

Here is how it looks like:

http://miki.nada.kth.se/~sebron29/asswiring/2.jpg
http://miki.nada.kth.se/~sebron29/asswiring/3.jpg

I went through everything quite a few times, and everything looks exactly like in the wiring diagram.

This is the result:

Position 1 (bridgemost): Both coils of bridge pickup.
Position 2: Inner coil of bridge pickup, outer coil of neck pickup.
Position 3: Both coils of both pickups.
Position 4: Outer coil of bridge pickup, inner coil of neck pickup.
Position 5 (neckmost): Inner coil of neck pickup only.

Correct would be:

Position 1 (bridgemost): Both coils of bridge pickup.
Position 2: Outer coil of bridge pickup, outer coil of neck pickup.
Position 3: Both coils of both pickups.
Position 4: Inner coil of bridge pickup, inner coil of neck pickup.
Position 5 (neckmost): Both coils of neck pickup.

The pickups are DiMarzio 36th Anniversary PAF's. Does anyone have any idea what might be wrong, given the result I get? It seems like the bridge pickup has gotten reversed in some way, and that the outer coil in the neck pickup seems to be "dead" in neck-only position.

Any information, ideas or thoughts are greatly appreciated.

Perhaps this helps aswell:

I also found this wiring diagram, can someone explain the difference between this one and the one I have used?

Thanks a lot in advance!

Best regards,

Did you get the wiring diagram from EBMM? I would just follow that. Also the switch might not be like the super switch on the ASS, so it might have to be wired differently.

Uhm, I do have the EBMM wiring diagram. But since this is a different switch, it's not really useful in this case. It's new DiMarzio pickups, and a new DiMarzio switch. Therefore, I'm using the wiring diagram from DiMarzio.

It's hard to tell exactly what's going on from the pictures. The right side of that switch (the pickup select side) looks ok according to the Dimarzio diagram. I can't see the wires all that well on the left side (the coil split/select side), and that's where the problem is.

It's possible the switch acts differently, too. There are different versions of that type of switch (the EBMM wiring is different), so wondering if that's a factor. Getting in there and testing for continuity with a multimeter is the real way to tell what's going on.

The schematic is pretty straight-forward- either the switch isn't connecting as expected on the left side or you've miswired something. Again, can't really tell from here.

Are you missing jumper wires on the switch? Look carefully on the diagram, there are some jumper wires between terminals, including one between sides.

I've used that exact same switch and diagram to install 36ths on my ASS, and it works and sounds great.

The only problem is the switch tip is a little short, I had to superglue the tip onto the blade when I was done.

Yes, I have made sure to do exactly like the diagram, including the "internal" ones.

So, what if we approach it from the other end. Say that I wanted to wire it the way I ended up with:

Position 1 (bridgemost): Both coils of bridge pickup.
Position 2: Inner coil of bridge pickup, outer coil of neck pickup.
Position 3: Both coils of both pickups.
Position 4: Outer coil of bridge pickup, inner coil of neck pickup.
Position 5 (neckmost): Inner coil of neck pickup only.

How would I wire it in that case?

Perhaps I can get a good idea of what's wrong by comparing the two.

Alright, this is very weird!

All of a sudden, the neck humbucker started to work. Now the only problem left is that the bridge humbucker has reversed coil tapping. That the inner coil is on in position 2 and outer coil in position 4, when it's supposed to be the opposite.

A real n00b question: Is this where phase shifting comes in? Like, would the problem solve itself if I reversed the phase of that pickup?

Question: do you have the orientation of the pickup correct? Eg is the bridge p'up physically in backward?

From your wiring, it looks to me like you have it right. So "inside" might just be facing the wrong way, etc.

Answer: Yes, the screws are the outside coils and the blanks are the inside rows!
