I had an old “Mighty Mite” single coil that was damaged and the coil was very hard to remove, how come?
Mighty Mite pickups were made at a Southern California company called Turbo-Jet and the bobbins were wound using a bondable wire. After the bobbins were wound, the coils were heated in ovens and the special insulation would bond to each other making a solid coil. The coils were difficult to remove if the bobbin needed rewinding or turns needed to be removed. There are other bondable wire s that are activated by chemicals but can get very messy when working with them. I prefer a hot wax solution used with a vacuum to draw the air bubbles out and this allows the pickup to be repaired easier and potting with epoxy also makes the pickup almost impossible to repair.
