Double-Waxed Pickups: Epiphone utilizes a double vacuum waxing process that ensures optimum performance. The pickup is first placed in the specialized wax vacuuming system before the cover is put in place to ensure that the wax fully penetrates to the very center of the pickup and solidifies all parts. After the cover is placed on, it is again given a second vacuum wax bath until the unit is completely saturated with wax.
