That was my first instinct, but then they also have the MACH II designation. 4 L is indeed the four leads you'd need for series and parallel wiring, so in the context of the bass that makes sense.A= alnico =FDV= fury Dingwall vintage= FD3A
N= neodymium =FD3 = FD3N
IIRC
Regardless of the pickups, DAS!
