Previously installed, small crimp on one wire that exposes ground wrap. Everything works, electrical tape or shrink wrap will fix. Priced accordingly.
For anyone looking, I just built up a J bass with a set of these and am really happy with them. Super versatile and dead quiet. Didn’t know much about them and felt like I was taking a chance and it paid off. I was hoping for a a pickup that could rock and also get that bridge Jaco sound as well and these deliver.
