The effect of repotting pickups?


Recommended Posts

Anything that can vibrate on a pickup can cause feedback: the covers, loose bobbins, a loosely wound coil, a loose baseplate (Tele pickups), loose magnets, etc. Humbuckers with the covers can excessively feedback too, so you can pot them with the covers on to minimize feedback. The idea is to fill the space between the bobbins and the cover and secure everything in place.

In order for the wax to penetrate the coil, the entire pickup first has to be as hot as the wax's melting point. That takes time. As the wax penetrates the coil you will see air bubbles coming out of the pickup. It is not saturated until the bubbling stops, which takes about 10 minutes. The tape around the coils does not need to be removed, the wax will get in just fine. It is absolutely crucial to monitor the wax temperature and keep it below 140 degrees or else the bobbins will melt and distort, killing the pickup. A special blend of wax and beeswax guarantees a low melting point. Wax that is heated too much without temperature monitoring can spontaneously combust, so keep the temperature as low as you can without the wax actually setting.

A "double boiler" is the best way to heat wax. This involves putting the wax in a container, and then putting that container in a pot of hot water. The Water is heated directly by the heat source, not the wax container.

After the ten minutes, get the oickup out and onto some kitchen roll to absorb the wax that'll run out, and give the top face a wipe, as it'll save a lot of cleaning wax off later.

yoink to that guy....thank god for copy and paste!!!!!!
