Seymour Duncan announces the Hot Stack Plus

For Stratocaster players, it's the challenge of the ages: keep the tone, but ditch the annoying single coil hum. A few years ago, we came out with the patented Classic Stack Plus pickup that answered the call. But what about those players who want a Strat tone that's bigger, beefier, ballsier, and brasher than vintage? For them, we are happy to announce the release of the Hot Stack Plus, the latest advancement in the quest for hum-free Strat tone.

Like our Classic Stack Plus pickup, the Hot Stack Plus uses a top coil that is significantly larger than the bottom coil-it's almost the same size as a traditional Strat pickup coil. This, together with the staggered, sand-cast, Alnico 5 pole pieces, and the custom wound, high-output coil, delivers a hot and thick Strat tone. Use a Hot Stack Plus in the bridge position together with two Classics in the neck and middle for a versatile setup that covers all tones from vintage to high-output.

The top coil is shielded with a “flux transfer plate” which attracts hum and “injects” it into the much smaller bottom coil, whose sole purpose is to eliminate the hum. The top coil gets the tone. The bottom coil kills the hum.

In addition to the unique design, we use a device seldom seen outside a physics laboratory called a Helmholtz coil, to calibrate each individual Hot Stack Plus pickup for maximum hum cancellation. The Helmholtz coil generates an extremely uniform magnetic field that allows our engineers to accurately simulate, on the test bench, the noise conditions found in a typical performance environment. This type of testing and calibration, in addition to the unique magnetic structure of the Hot Stack Plus system, allows it to achieve extraordinarily low levels of 60-cycle hum. The Hot Stack Plus works great with all of our stompboxes, especially the new SFX-11 Twin Tube Blue and SFX-10 Vu Delay.

Most Strat guitars, the Hot Stack Plus is a direct retrofit. 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 built and tuned, by hand, in our Santa Barbara, California workshop and includes mounting hardware and detailed wiring instructions. Recommended for bridge position.
