Sometimes pickups can be repaired by finding the break in the coil. If the break is at the end of the coil it can easily be unwrapped a wind and reconnected at the eyelet. If it occurs at the start of the coil it is not possible since the wires do not have any slack. To join the ends I will add a small piece of shielding foil to make a bridge bewtween the wires. Even though it wil not be visible I like to disguise the repair so it isn’t as conspicuous.
