Old Höfner pickups are common visitors at the workshop for re-winds. The insulation breaks down on the winding wire they used and they become open circuit and simply stop working.
Although these are built like humbuckers magnetically with 2 rows of pole pieces powered by a single bar magnet they have a single coil inside them.
The bobbins are often very fragile. They’re made of thin plastic and can deform easily.
I was happy with how they came out in the end.
If you have any dead pickups, get in touch.
