The regular Gibson Custombucker is standard equipment on the Gibson Custom Shop’s Historic Reissue guitars and beloved by players worldwide for its legendary Patent Applied For tone. Years of research and testing by Gibson engineers resulted in a formula and process that replicates the sonic magic of the original Patent Applied For humbucker™ pickups from the 50s. Each Custombucker uses Alnico 3 magnets for a warm, sweet tone that accurately delivers the sonic characteristics of those highly cherished early humbuckers. Like the original Patent Applied For humbuckers, the Custombucker uses 42 AWG wire and unbalanced coils that are left unpotted for a historically accurate pickup that will please even the most discriminating player. The Custombucker Underwound retains all of these features of the regular Custombucker, but it has fewer windings on the bobbins, which results in more clearly defined overtones and harmonics. It has a brighter tone in the rhythm position, making it perfect for pairing with a standard Custombucker in the treble position.
