Hello Nutz people I have a friend who wants a custom wiring. Of course I didn't find any place to get to but here. He has the Dimarzio Breed pickups for both Neck and Bridge and HS-2 in the middle.I guess the HS-2 is a Single Sized humbucker as it has 4 conductor wires. He also want to use a P/P pot for Single/Humbucking mode. That was my idea also but I wanted Parallel/Series combination as well. John knows that Here what he wants: Volume is pushed down (Humbucking) 1. Neck (FULL - HUM-CANCELLING) 2. Neck + Middle (FULL - HUM-CANCELLING) 3. Middle (FULL - HUM-CANCELLING) 4. Bridge + Middle ( FULL- HUM-CANCELLING) 5. Bridge (FULL - HUM-CANCELLING) Volume is pulled up (Singles) 1. Neck (Splited - Single) 2. Neck + Middle (SPLIT - HUM-CANCELLING) 3. Middle (Splited - Single) 4. Bridge + Middle ( SPLIT - HUM-CANCELLING) 5. Bridge (Splited - Single) EDIT: Thanks John for noticing the SPLIT and FULL mistake. As I see positions 2 and 4 are common, That makes the project easier. Also, Does he need a 5 way superswitch or the Import switch will work ? He is thinking of applying that diagram. In the diagram, all pickups are SC-sized humbuckers. But I don't know if this will work or not ? www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=1lil1v1t5w3sSo, is there anybody for the rescue ?

The SD diagram will do just what it says. You can use it, assuming that your friend's guitar has a std 5-way switch as shown on the diagram.
The fact that the diagram uses SC-sized HBs makes no difference, so long as all your friend's pups are 4-wire HBs as well.
You (or he) may also need to check polarities of his particular pickups to ensure that the 2 and 4 positions are indeed humbucking. The SD diagram assumes the use of 3 identical pickups (well, a matched set of three, anyway), and your friend's may be different since he's not using identical ones.

Thank you newey. We will try it and see how it works !

Also remember that the Seymour Duncan diagram will no doubt use (you guessed it) Seymour Duncan pickup wire colors. DiMarzio uses different colors for their pickup wire colors. Here's a chart: Also the gray wire in that diagram is meant to represent white.

I think that is a good diagram, and since all his pups are dimarzio, the humcancelling should work out provided you translate the colours from Seymour Duncan to Dimarzio. THe only thing is that I see you list 2 and 4 with one split and the other full. With that diagram, with knob down, both will be full and knob up, both split. I think that is better anyway

wolfOfc, i took that into account @john Thanks John for noticing the mistake. I corrected it. But as far as I know that both pos 2 and 4 are the same in both cases, either the Knob is Up or down. They are hum-cancelling in both situations. I have a question too. This is Herman Li pickup configuration, I think Pos 2 and 3 are not hum-cancelling when the Knob is pulled up. Am I right?

McLord- If those positions are hum-cancelling with the knob down (unstated assumption), then yes, they aren't hum cancelling with the knob up. Also, to be precise in our terminology, the coils of the HBs are not being "tapped", rather they are "split", or one of the 2 can be said to be "shunted". The term "coil tap" refers (if one is being precise) to a single coil which has a center "tap" connection allowing the use of less than the full coil windings (i.e., lowering its output). I know this because I was similarly corrected when I said "coil tap" once.

John, Newy, I need help There is something I can't out with this diagram. As far as I see, the SD pickups are all placed with the same rotation meaning, N,S,N,S,N,S which brings me to this IF we said Ninner, Nouter, MN, MB, Binner, Bouter, Will that What I will get with the diagram; Pushed Knob: 1. Nouter + Ninner 2. Nouter + MN or (Ninner+Nouter + MB+MN) 3. MN + MB 4. Binner + MB or (Binner+Bouter + MB+MN) 5. Binner + Bouter Pulled Knob 1. Ninner or Nouter ? 2. Ninner + MN 3. MN or MB ? 4. Binner + MB 4. Bouter or Ninner ? (Correct that scheme for me, If anything is wrong) I think the ? depends on if the North is Upwards or Downwards. It could be like S,N,S,N,S,N. So that will differ a bit, right ? That diagram is confusing a bit because of the SC-Humbucker in the middle. Thank you

mclord - if you are refering to the Seymour Duncan diagram, the single coils that are selected when you pull the knob are the slug coils of N and M, and the adjustable coil of M. That would assume that you were using a normal Seymour Duncan humbucker, with one adjustable set of poles on each. Take a look at the key that I put on your HSH design diagram. The same principle will apply if you translate to DiMarzio colours
With that wiring, it ensures that positions 2 and 4 are humcancelling because it selects a differnt col from teh middle as from neck and bridge. What is not obvious is how these positions will relate to inner and outer coils, it depends which way round they are placed, and you can choose that.
I have some covered humbuckers, and I find that the single coil sound is better on the adjustable coils.
I think the way to proceed is to put the pickups all facing the same way, and decide whether that is slug coils towards the neck, or towards the bridge, then work out colours to suit. If you decide that, you should be able to work it out, but we can help if needed.
John

mmm, I really got confused a bit. Well, Both his humbuckers in Neck and Bridge has adjustable poles for each coil. The SC-Humbucker, It just has one adjustable I think ! The Humbucker The SC-humbucker What is the Slug coil anyway ? Another problem, he doesn't want to understand anything. He just wants the results. So here I need to understand everything. Thanks to you ofc For me, I will never care what middle coil will be selected when the knob is pulled. All he needs is just hum-cancelling. So here what he wants. I want to learn here I think, yes, They will be all placed in the same round. Just another question. The Neck + Middle (4 coils) will be activated in Pos 2 and (Bridge + Middle) in pos 4 as the knob is pushed down. Right ? And when pulled up, the slug coil of neck + Adjustable coil of M in Pos 2 as well as Pos 4. That means that in these positions, the activated Middle coil will be the same in Pos2 and Pos4. Right ? It differs inner or out depending on the round of the pickup and if I want the neck inner coil, to be activated in Po2. I have to rotate the pickup 180 like in my H S H guitar, Right ? Having an extra coil confuses me a lot EDIT: I will be applying the SD wiring in Dimarzio pickups, just translating the wires. Is there a dis-assembly image of such SC-Humbuckers ? I want to see them from inside

I believe that middle SC sized humbucker has stacked coils, one below another. When cut to a single coil, one coil will be stronger and that is the one you want in coil cut mode. You can test this by touching the leads for each coil to a guitar cord and tap the pole with a screwdriver tip - to see which coil is dominant.
Based on that, we work out how to wire the middle pup, and then the neck and bridge pups so that humcancelling with M is achieved, Then, you work out which coils on neck and bridge are being selected and you rotate the pups to suit so they are the inner coils (if that is what you want).
I think that's as far as we can get until you can work out which two leads on the middle pup give the best signal.
cheers John

I will go with the SD diagram and see how things go ! Thanks John
