pups are original, and same constuction as in my Ibby SR506-:
both are: (---__), not dual coils like (======).
If you use a piece of cutoff bass string or small screwdriver to see where it is attracted to the magnets, then you'll know how yours are made.
The 'P' split pups are humbucking, but narrow aperture, more like single-coils than dual-coils. Quad coils are like this, but with 2 'P's, regular and reversed.
Seems to me that the split pups have more definition/ fundamentals than dual-coils- like them for that.
