In Gibson's plant in Kalamazoo, Michigan, the earliest Gibson PAF (“Patent Applied For”) humbuckers were wound on machines that gave imprecise and inconsistent results, meaning the pickups came with varying degrees of output and tone. The '57 Classic is a near perfect re-creation of a late 1950s humbucker, delivering a warm, even tone with full, even response. From clean to crunchy, the '57 Classic delivers all the richness of an original 1950s humbucker. Used in the neck position, the '57 Classic is the perfect complement to the slightly overwound Classic Plus in the bridge position. These pickups are so authentic that they even carry the original "Patent Applied For" decal on the baseplate.
