Bought a pickup on the Bay, described as a SD SCPB-3 (quarter pound). What showed up was a different beast (pics below). It's a stacked config with four conductors (red, green, black, white) plus shield. Green and black were twisted together. Poles are 1/4" in dia with raised A & D and the impedance (both coils in series) is 17.82 kohm. Some have suggested that it might have come from the Duncan custom shop, but the back plate is completely oval and every other Duncan SCPB I've seen has the protruding "lip" where the leads are soldered to the output wires. Anyway, if anyone could help ID this pup, I'd be grateful. I bought it as a potential replacement for the stock pup in my Fender CS 55P NOS.
