Once I got a look at them, I could see they were sealed. Didn't know that.I was referring to the two coils inside each pickup. The pickups are sealed so you can't tell how they are wired by looking. The FD3 Mach II pickup came out in about 2007. It was the same as your pickup but the coils were wired in series instead of parallel. The current version is called the FD3-4L, meaning four it has four leads so you can choose series or parallel.
So at this point, the options seem to be:
- Find someone selling a set of FD3 or later pickups
- Replace the pickups with something different (I'm looking at you, Nordstrand Big Splits)
- Live with it because it sounds great as-is
