This is a Seymour Duncan SSL-7, but it's junk. It produces sound, but there's no continuity. I think it's on the verge of losing sound completely. Please consider it as completely junk. Normally, the SSL-7 has pole pieces that protrude from the bobbin, but this one has the pole pieces recessed flat. It looks like an SSL-4. Please be aware of this as well. Thank you for looking.
