Can epoxied pickups be rewound?
Probably 95% can t. As the epoxy solution is drying, there can be a chemical reaction with plastic parts within the pickup and the epoxy can actually bond with the plastics. The epoxy has a thick viscosity than a hot wax and cannot always fill the fine voids and cavities within the pickup. The epoxy can sometimes be chemically removed but it will do damage to the other plastic parts such as the cover and plastic bobbins. The epoxy potting solutions don t seem to penetrate through the coils to keep them from becoming microphonic.
