This is a Seymour Duncan humbucker pickup. I bought it used and was planning to install it, but I ended up selling the guitar I was going to put it in, so I never used it. I don't have a tester on hand right now, so I haven't been able to confirm that it's working. Therefore, I've lowered the price considerably. As you can see, it has a socket, but you can remove it and use it with standard soldering. It had a lot of scratches when I bought it, and it shows a fair amount of wear. There is no outer box, only the pickup itself will be packaged and shipped in a cardboard box.
