Since their introduction in the late 1950s, Gibsons famous “Patent Applied For” humbuckers have been considered the ultimate pickup because of their smooth, velvety tone. The 57 Classic Plus uses slightly overwound balanced coils, exactly like the original PAFs of the late 1950s that accidentally received a few additional turns of wire. They are the perfect bridge-position companion to the 57 Classic, delivering just a little more of “the sweet stuff” without sacrificing any of the rich vintage tone. Each 57 Classic Plus humbucker features the same enamel-like coated wiring, Alnico II magnet and maple spacers as in the original models, achieving a creamy, smooth output that sounds rich and full whether theyre being played clean or overdriven. The 57 Classic Plus pickups are so authentic that they even carry the original “Patent Applied For” decal on the baseplate. All of them come with braided, two-conductor wiring and are fully wax potted to eliminate any chance of microphonic feedback.
