The original Jv pickups (I still have all but the bridge) were not RI Fenders - they were just old US stock that Fender sent to Japan, nothing magical in my opinion, but not poor - so they are Alnico V and probably with polysol wire.
In my view Apaches even with A3 would kill the old Fender pickups in a tone/output test - Mother's aren't Rory hot, they are smooth with a bit of bite.
What amp do you use? I could record a basic comparison between Mother's Milks and Apaches - playing the same thing, although the JV has a basswood body and the 60s MIM has an alder body, so you wouldn't get an exact difference. I also prefer rosewood necks, so that would make a slight difference.
