The complex and distinctive sound of the old Stratocaster guitars was due to the narrow, sharply focused magnetic field of the single-coil pickup. With staggered magnet heights, Seymour Duncan's Classic Stack pickup duplicates this much-sought-after sound. By stacking 2 coils on top of each other, the annoying noise and hum of the single-coil pickup is eliminated. Available in white or black. 4-conductor cable.
