Some of you have heard of pickup potting and wrapping. For those reading this article who do not know what this is, let me start by explaining why this is done. A pickup is constructed with a fine copper wire wrap around magnets consisting of thousands of turns. Hand wound pickups (which produce the best tones), have irregularities in them that can leave wire in the winding loose underneath the outside winds. Potting a pickup is a process of submerging it in a heated, liquid mixture of parafin and bees wax to secure the winding. Wrapping with cloth or cord is another method. The reason for doing this is to keep dirt out, reduce or eliminate inner coil movement and to keep the pickup from becoming microphonic. Vibration transmitted from the strings and movement of the guitar can cause the winding to become loose, short out the coil or become microphonic. To check for a microphonic pickup, plug you guitar into your amp and talk into the pickup. If you can hear yourself through the speaker then your pickup is microphonic. Another indication of a microphonic pickup is a "howling" when you get close to your amp and you have your hand on the strings dampening them. Services Performed: For some single coil pickups as well as humbuckers, specification call for cord or cloth. I wrap the pickup assembly according to specifications, reassemble and test. Install pickup in guitar, clean and polish guitar. |
