Seymour Duncan Classic Stack Plus for Strat Single Coil Pickup White

The Classic Stack Plus is the ultimate advancement in the quest for hum-free Strat tone. The top coil is similar to a traditional Strat pickup coil. This, together with the symmetrically staggered, sand-cast, Alnico 5 pole pieces, delivers very authentic, traditional Strat "chime." The top coil is shielded with proprietary "flux transfer plates" which intercept most of the hum and "inject" it into the much smaller bottom coil, which cancels any residual hum left in the top coil. The top coil gets the tone. The bottom coil kills the hum. 
In addition to the unique design, there is a device called a Helmholtz coil used to calibrate each individual Stack Plus pickup for maximum hum cancellation. This type of testing and calibration, in addition to the unique magnetic structure of the Stack Plus system, allows it to achieve extraordinarily low levels of 60-cycle hum.
The result is all the traditional chime and "quack" from your Stratocaster, but without the annoying hum. Please note that the Stack Plus is .995" (25.27mm) tall, which makes it .175" (4.45mm) taller than a vintage pickup for Strat guitars.
Includes mounting hardware and wiring instructions.
