Aesthetic Choices
You can find Humbucker covers in a variety of colors, patterns and materials. Common humbucker covers are made of nickel silver and come in many coating styles. The cover hides the interior elements of the pickup: bobbins, baseplate, coils and even the magnets.
You can find covers made from plastic and even wood. Choosing a color, texture or pattern depends on your personal taste. Some manufacturers offer unique cover styles for their own pickup models, so sometimes you might have to choose between aesthetics and sound.
