I could use a little help identifying SD Jazz Pickups...

    Hi guys, I am having a hard time identifying a couple of SD pickups that I pulled out of a 78' Jazz Bass.

    According to SD there should be a number somewhere which could help identify the actual models. However I have gone over both pickups and there are no numbers, or any identifying marks (to my untrained eye) that I could find.

    So I thought to upload some photos and see if anyone more familiar with SD pickups could recognise them! As I said, these were both pulled from the same jazz bass, although they don't seem to be a part of a set, just a couple of odd fellows. One has a really faded Basslines logo, the other has a SUPER faded Seymour Duncan script logo.

    Thanks guys I really appreciate it!

    Better pics would help a lot.

    The bottom one is a stacked humbucker for sure. The exposed pole pieces make it an STK-1, STK-2, or Lighting Rod if it's active.

    Thanks for your help. Sorry about the pics, not great I know. I will take some better/lighter ones later! The pickups are definitely passive, so I will have a look at STK-1 & STK-2's to see if there is a way to distinguish between them:/

    Oh I forgot to mention, the top pickup in the photo is wrapped in a copper foil.

    i wonder if the copper foil was added later. if somebody tried that to reduce the single coil hum, it won't work for that; it'll also dull the highs a little bit.

    you can narrow down what they are (as well as telling if they still work) by reading DC resistance, then looking up duncan's "tone chart" to see which ones come closest.

    They were very noisy pickups - a lot of hum, so I wouldn't be surprised if someone did add the foil in an attempt to chill it out. It looks pretty pro though.
    I don't have any way of reading resistances, I might have to take it to the shop down the road and see what they reckon. Cheers!

    even the stacked one? tone considerations aside, that one should have been dead-quiet.

    The neck pickup was really noisy, I remember that. So maybe the stacked was by the bridge? I will check when I am home tonight as they are slightly different sizes so I will be able to see which one was where.

    that would make sense though! Maybe the previous owner thought the neck was noisy so wrapped it in foil in an attempt to shut it up, to make it more like the stacked...
