This is a pickup from a Jackson (Grover Jackson at the time) Soloist. There is no model number listed, but it has the Duncan logo, and according to the catalog specifications of the time, it is likely an STK-S1n. The reason for being junk is that the white lead wire on the pickup body is broken as shown in the photo. I was able to measure the resistance while holding it with my finger. I will sell it to someone who can repair it. Please consider purchasing only if you understand the following regarding the used item: ・There is some rust on the pole pieces. ・The remaining length of the lead wire is approximately 18cm. ・I am not sure if the PU cover is genuine. ・Everything in the photos is included. Please note that screws etc. are not included. ・I have cleaned it as much as possible, but as it is amateur work, there may be some dirt that cannot be removed. Please refrain from purchasing if you are looking for a beautiful item. ・Please understand that this is a used item, and no claims or returns will be accepted.
