Can you help identify this Pickup and the color-coding?

hi Forum Duncan-ites!

Am hoping someone can positively identify the model of Duncan pickup and the coil color-coding?

Would like to wire the pickup to a mini-toggle to get split/full ...

It is some type of Duncan Stack of mid-80's vintage (approx 1985?) and I'm wondering what "north" and "south" will mean on this, since they are above/below each other?

Appreciate your taking a look ...

It's a STK-S1 Classic Stack for Strat. They're wired similar to 50s Fender single coils, so the top coil is south and that coil will be active if you wire a typical SD coil split with the red & white to ground. As an added bonus, it'll hum cancel if combined with the slug coil of a SD humbucker.

Great info, thanks Foamy - I found another post (on Harmony central) that says that the second (bottom) coil is a dummy - which is what I think you're describing in "combining with slug coil" ?

It isn't a dummy coil and you could absolutely split to it if you wanted to. However the output would likely be significantly lower, so there really isn't a good reason to do so.

The remarks about combining with a slug coil apply to using the Classic Stack as the middle in a HSS or better yet, HSH setup. For the HSH setup the top coil of the stack will be RWRP relative to the slug coil of either humbucker, resulting in hum-canceling auto splits in positions 2 and 4 if a superswitch is used. For the HSS you can still get hum canceling with the bridge humbucker slug coil in position 2, while position 4 hum-canceling would require a RWRP neck pickup.

Thanks dystrust, that makes more sense - though not a setting I'd use often, having the split-single-coil available can be useful at times for softer musical sections or to emphasize the higher frequencies.
Appreciate your replies ... rock on!
