A CHEAP, EASY SOLUTION TO MICROPHONIC FEEDBACK
Sometimes, for no apparent reason, a guitar can suddenly start suffering from feedback that is uncontrollable and unwanted. This is called microphonic feedback, and it can be very annoying. It is not to be confused with harmonic feedback, which happens when you hold a note or a chord for a long time, and gradually fades into an endless "ringing" until you stop it. Microphonic feedback can occur just from standing next to your amplifier with your guitar. In fact, in some cases you can even talk into your guitar pickups and hear your voice through the amp!
Thankfully, microphonic feedback can be easily cured. It occurs when the magnetic coils in your guitars pickups become slightly dislodged, resulting in air gaps between the wires. Wax potting is simply a process of dipping the pickups in wax that fills these air gaps, holds the magnetic coils in place and the result is that you no longer suffer from microphonic feedback! The process takes around 25 mins as well as special techniques and certain kinds of wax at specific temperatures.
