Duncan with Dimarzio pickup

[CarlosG]

Hi!
I have TB-4 bridge and FS-1 middle. Great combo.
But they played out of phase and I had to reverse the colors on fs-1 (white to ground, black hot).
Unfortunately, there is no hum canceling in combination with the Seymour Duncan slug coil.
Would rotating the magnets help here, or is there some other trick? is there fs-1 rwrp? Does rwrp giving hum canceling change the sound?

you should be able to make them in phase and humcancelling, but itll take some futzing. is the slug coil in phase with the fs1 now?

 

[CarlosG]

When fs-1 black wire is hot and white is ground, yes i have phase sound with slug JB coil.
I don't have a Duncan Neck pu yet, but I will also connecting fs-1 it with a slug Neck pu.

The FS-1 is standard with North magnetic polarity since it was originally intended to be hum-cancelling with Fender S/C pickups. To get a South magnetised version you could order “DP110-S”, however you still need swap the wires to be in phase with SD.

I'm not sure if all DiMarzio single coils have the phase reversed compared to Duncans, but I could swear I remember haviing to wire in my SDS-1 backwards to work as well? I could be wrong.

Try to wire it with your screw coil. All diagram you need is;

I prefer slug coil sound.
I wonder if rotating the magnets in the fs-1 might help?
I don't see FS-1 rwrp anywhere on mine.
If nothing can be done, I will buy SSL-5/SSL-6, but then I don't know whether regular or RWRP.

I think the FS1 has a plastic bobbin but I wouldn't swear the rod magnets aren't glued in it. I wouldn't try to pull them off.

Anyway: if you flip the magnet of the SH4, it will change the bobbin with slugs in South coil. If then you swap the hot / ground wires for one of the two pickups, it should make them in phase and hum cancelling with your favorite wiring option.

 

[CarlosG]

Rotating the magnet changes the phase of the pickup, right? Will it change the sound of the sh-4?

I normally had to reverse the hot and ground to play in phase, so by reversing the magnet I should use the standard connection?​

No, it will not.

Yes.​

Yeah, flipping the SH-4 magnet is the simple solution here.

I flipped magnets on FS-1 (has plastic cylinders), I connected it as standard (white for signal) and it's work. No hum on 2 and 4 position.
Rotating the magnet is very easy. First I recommend painting one side with a marker so you don't mix it up. Just squeeze and push the other way around. Sounds great in 2nd position with JB.

Good to know. The last DM's that I've modified had glued magnets that I couldn't flip or change, for the record.

I still think that flipping one single bar is not necessarily less easy than pulling off and on 6 rod magnets but if the result makes you happy, nothing else counts. Enjoy...

Now I can get close sound like celans on Whitesnake-Is This Love.
