I searched high & low on the internet for 5-string white or vintage cream jazz pickup covers. To my knowledge, they simply don't exist. So I made my own set. I used several coatings of Krylon Fusion (Buttercream color) on the casings after removing the pickups. Sometimes glue-like adhesives are used inside the casings to hold the casings onto the pickups and so they can be stubborn to remove from their casings, some are easy.
