This is a Seymour Duncan SSL-4 Quarter Pound single-coil pickup. Seymour Duncan I'm a Ritchie Blackmore fan, so I swapped it with an Yngwie Malmsteen pickup, but the coil broke before I used it much. As you know, this model doesn't have a cover, and the coil is only wrapped with cloth tape. I had the front pickup set high, so it often made contact, and finally the coil broke all at once, and no sound came out. I haven't used it much, so the appearance is relatively clean. There are 3 or 4 places where the coil is visible from between the cloth, and I've included a photo in the second to last image showing where it likely broke. I was going to rewind it, but I don't have any plans to do so, so would anyone who can repair it be interested? Shipping included via Yu-Packet Post.
