Q about cheap pickups in a JB-62 Japan

[Babystrad]

Hi guys !

So I've got this JB-62 Japan body which was said to be a 62-US (so with the American made pups and threaded saddles) from a pro dealer.
Well, it was not the aforementioned said US Japan model.

Anyhow, any idea what these poor sounding pups may be ? Here's one of the set. Thank you all in advance for your knowledge. Best from France.

USA Fender Pickups typically have alnico magnets. That pickup has of course ceramic
Magnets. Who knows what brand that is.

Yep. Indeed. But intrigued by these ceramic magnets. Never saw a jazz pup like those in this bass, with these two magnets longitudinally side by side. Wilkinson have something similar, but not quiet the same. Those are at least 20 years old for additional information. And (originally) glued in their cover cases.
