Have a set of HS working in Single coil mode ( back and white's to ground). Standard strat 5-way switching. This is not noise cancelling as the pickups are working in single coil mode. But positions 2 and 4 are not noise cancelling like in a normal strat. Why is that? Do i need to switch some of the wires on the middle pickup? Swap green and red on the middle or something else?

Re: Dimarzio HS split and noise cancelling issue.
It’s not hum canceling because the polarity is wrong.
Try connecting the B&W wires to hot instead to split it. That will select the other coil.
You also don’t have to split the pickup in the 4&5 positions. If they are bright enough you will get that phase notch. I never split mine.

Re: Dimarzio HS split and noise cancelling issue.
In this pup only the upper coil senes the string. The bottom is just for noise reduction. So while phase is not a problem with humbuckers because both winding and polarity can change, with single coils this is not so. So,
a) with the current do you get a strong signal (even stronger than in standard humbucking in series wiring) in positions 1,5? if yes, this means you use the correct (upper) coil
b) in positions 2 and 4 do you get (besides noise) a weak signal? if yes then you are lucky, you just inverse the polarity/winding of the mid pup and you'll get a strong signal and noise free
if no, then you will have to go and get a RWRP pup with relation to the HS3
3rd solution just get a HS middle and wire them all up in humbucking wiring. This is not so bad. But I agree that in single coil mode they sound much better and stronger.

Re: Dimarzio HS split and noise cancelling issue.
I'll test this. Dimarzio says to never use the bottom coil as it is too weak to use. I believe that's what this will do. BTW i have the BW wires going to the different points on an S1 switch when depressed, grounds them for single coil mode. Very versatile and single coil mode is more stratty.
I have a feeling swapping the green and red wires on the middle pu will solve this.

Dimarzio HS split and noise cancelling issue.
Oh I didn’t realize you are doing a stack.
Yeah that won’t work.
The thing with hum canceling pickups is you can’t combine them with single coils to buck hum. Both pickups need to be picking up hum.
But the magnetic polarity and electrical polarity must be opposite.
As I mentioned, I only use hum canceling pickups. Most as the little SC size humbuckers. My Parker has an old Lawrence L-250 in the middle. Generally any bright middle pickup will help get those quack tones without resorting to splitting coils. The problem with splitting a humbucker is it usually doesn’t sound like a “real” single coil because it’s not wound the same. Unless it’s a very over wound humbucker.
In those cases I still don’t split. I switch them into parallel.
If those are three stacks there’s no reason to switch out the bottom coils. They already sound like single coils (i.e., extended upper harmonics).

Re: Dimarzio HS split and noise cancelling issue.
I'm not combining anything. I have 3 Dimarzio HS stacked single coils. The S1 allows me to run them all in single coil mode . When i do single coil mode, position 2 and 4 should be noise cancelling but they arent.

Re: Dimarzio HS split and noise cancelling issue.
They shouldn't. In order two SC pups to be in phase and noise cancelling with each other they must be RW/RP with each other. If you wire all your identical HS3 in single coil mode using the upper coil , *APPARENTLY* bridge/mid wont be RW/RP to each other, and the same will be true about mid/neck. Your only hope, (provided you insist on SC) is to wire the bottom coil of the mid pup. This way they will be in phase and hum cancelling but the sound in mid pup will be even weaker. Hmmmmm you could also try noise cancelling and out of phase with the upper mid pup coil with inverted polarity.
Or as I said just wire them all in HB mode and forget about it.

Re: Dimarzio HS split and noise cancelling issue.
They are stacks. There’s no reason to run them in single coil mode. Just pretend they are real single coils. There’s no need to hum cancel since they already do.
Just wire the switch up like a normal Strat.

Re: Dimarzio HS split and noise cancelling issue.
The thing with those is that they sound bigger in SC mode. So going back to humbucking is like downgrade. But since he uses this S1 thingy its not a problem. Bigger sound is best utilized in clean channel. So no big deal.

Re: Dimarzio HS split and noise cancelling issue.
No they shouldn’t. You need a RWRP middle pickup for that. These aren’t made that way.
Aren’t S-1 switches supposed to put the pickups in series?
