Evidence: Guitar pickup potting is a process whereby the fine wire coils of a guitar pickup are encapsulated in a substance that inhibits movement of the coil. Guitar pickups are generally made from bobbins wrapped in many thousands of turns of fine wire. Generally, the potting medium is a wax mixture that is melted(see photo) and then permeates the wire coils.
