Seymour Duncan JB – Re-Wind

Seymour Duncan JB humbuckers are such a classic pickup, loud and aggressive with no shortage of high end attack.

This one had stopped working altogether. With the tape off the hook up wires are exposed and it’s possible to identify which coil has the problem. It’s usually just one coil.

It turned out to be the coil with the screws in this case.

The coil with the lugs in fine and showing 8.42KOhms and from that I can figure out what size wire they used and calculate the number of turns needed to re-wind the duff coil.

Pretty routine stuff this one but always nice to have a look inside a classic pickup.
