I have bought a set of used Breed humbuckers to replace the Evolution set in my Jem.
At the back of the neck pickup there is a round sticker with the letter R on it.
What does that mean? Reversed polarity?
Should this one be wired differently than the regular Dimarzio wiring?

you can also check the polarity by taking the breed bridge and placing the two pickups face to face and see if they attract or repel magnetically. The coil where the wire is coming out should repel the same coil on the other pickup.

If it turns out the polarity is flipped you have to open up the pickup's baseplate and flip the magnet. Flip it the long way, like a propeller if that makes sense

regular spacing?
F-spaced. It came of a Jem. Ibanez written on the bobbin.
I have measured it and checked polarity and it seems to be exactly like a regular Dimarzio.
The former owner told me that this neck and bridge pickup were wired black=hot, red+green=tap, white+bare=ground.
Don't know why Ibanez wire them like that but the result should be the same anyway I think?
It was just confusing with the R sticker on the back.

I got this message from Dimarzio support:

The "R" would usually indicate reverse-polarity, but there aren't many good reasons to do this, because both coils on the Breed are identical. Normal polarity is the South coil located over the cable exit, which is the best way to verify the polarity if you have a polarity checker or a compass.

If the pickup truly is reverse-polarity but the connections were unaltered, the normal JEM connections will not apply to this pickup. Instead, red=green and black=white.

that's odd, normal wiring should've been red=hot/black+white=tap/green+bare=ground

looks like the way it was wired they swapped the start and finish of the coils, which still works I guess just weird

Could be R for Rear, and F for Front pickup.
Perhaps. But rear pickup is for me the bridge pickup and not the neck.
One thing that cross my mind is if it's just something left from the production, a way to tell the person who assembled the electronics together at the the Fujigen factory that this neck pickup should be mounted reversed on the pickguard (cable exit to the neck). Or if Dimarzio used the R sticker so they were sure to write Ibanez on the right place on the bobbin top.
Anyway, both pickups are now installed the normal Dimarzio way and they sound awesome!!
