I've just picked up some 59/09s for my ME1, and the pickups have the 4-conductor wiring - red/white/black/ground. Looking at the wiring diagram for the Custom models with toggle, it looks like the pickups have opposing magnetic polarities(?) so some trickery is required on the push/pull so that instead of always switching the ground from coil to coil, on the neck pickup you're switching the hot (i.e. the ground is fixed):
If that's the case, does that mean I cannot use the 1.1k and 2.2k resistors for a partial split as on the DGT and MC58 models? I guess I could use one for the bridge pickup but not for the neck?
Any help greatly appreciated!
