These are the classic ’58-’62 era Jazzmaster pickups. Warm, rich, and twangy – expect a nice woody warmth, smooth high end, and warm bass. These feature black fiberboard bobbins, Alnico V flat poles, cloth leads, and wound with 8500 turns of 42 gauge Formvar coil wire (approx. 6.4K), with 5% increments available (10% overwind recommended for bridge pickup). Wax potted. RWRP optional.
