Bought a loaded pickguard, seller thought they were all Seymour Duncan Custom Shop Antiquities. Received it, and the NECK pickup looks to have the SD CS markings (signature and number), MIDDLE has not markings but looks like the NECK, BRIDGE has a Fender Custom Shop sticker on it. Pics are below. All three pickups have medium-height raised E & A poles, high-height D & G poles, flush B poles and slightly raised high E poles. Thoughts? Frankly, they all look alike, but the Fender CS sticker is throwing me.
