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.
