Danizmisljam rupu na saksiji:

"Potting a Pickup is the process of solidifying a coil against microphonic vibration by submerging it in a 130-F (54-C) to 140-F (60-C) degree bath of wax comprised of 80% paraffin and 20% bees wax. This ratio is something of an industry standard. It’s a good mix that insures the wax will saturate the coil well and will harden yet won’t become brittle.

Double Potting a Pickup is the same thing as above accept that the pickup is potted a second time after it's had metal parts added like the chrome covers of a PAF or the steel base plate that's on a Tele bridge pickup. This insures that the metal parts can't vibrate and cause microphonic feed back which has been known to happen. Teles bridge pickups are bad about this and some folks like to have the entire bridge potted with the pickup to prevent rattling springs or screws."
