EPK, you mentioned in a recent post about pickup dipping.
I've heard about this before, but is the actual physical process of dipping is very difficult?
Can I do it myself?
Don't mean to be ignorant, but is it as easy as dipping the pickup into a bowl of molten wax and letting it dry?
It's not difficult technically, but you've got to be careful with the temperature. Here's the method.
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.
Thanks a lot EPK.
Will the wax run when the guitar is played live, in a hot room?It shouldn't effect anything, should it?
You'd need to be playing an open air gig in the middle of the desert in high summer before you'd be even remotely in diffs.
If your guitar is prone to catching fire also, don't do it.
To end this off, i've found a guy who will epoxy all your pickups to stop microphonic squealing.
Mine, although wax dipped by the manufacturers, were squealing like a pig due to the wax having broken down.
Tony Hamilton, of R. Hamilton, TV and video repairs, Castlereagh Rd, will do this, fix amps, and do other sundry guitar repairs efficently and cheaply.

Nice one, thats a number for the address book. We may have a few little jobs for him...
