Seymour Duncan JB and Jazz model humbuckers. Unused and unopened. - Model: JB Model Humbucker - Model: Jazz Model Humbucker - Model Number: SH-2n - Model Number: SH-4 Thank you for viewing. I purchased these several years ago intending to install them in a guitar I was using at the time, but I ended up selling the guitar I planned to install them in, so I kept them unopened at home. I am selling them now to organize my equipment. Since there is no ESP seal, they are likely parallel imports. I am open to small price reductions and separate sales. Although they are unopened and unused, I am listing them as "Like New" due to long-term home storage. I hope you will consider them.
