Product Spotlight - Classic Stack® Plus
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, patent-pending design, we use a device called a Helmholtz coil 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. Note that the Stack Plus is .995" (25.27mm) tall, which makes it .175" (4.45mm) taller than a vintage pickup for Strat guitars. Each Stack Plus is hand made and tested in our Santa Barbara factory and includes mounting hardware and wiring instructions.
