Here's a very nice and clean Fender Standard Series Stratocaster pickup for the Middle Position as it is Reverse Wound Reverse Polarity (RWRP) from Fender Neck and Bridge pickups which will produce a hum-cancelling effect when in the notch positions.
Meters at 7.0 kΩ of DCR w/ 8" of "HOT" lead and 5" of "GROUND".
