The Seymour Duncan STK-J2B Hot Stack is the perfect choice for bassists who want more punch, more output, and a assertive midrange from the bridge position of their Jazz Bass—without sacrificing the classic single-coil character. This stacked coil pickup for 4-string electric basses delivers a fat, midrange-focused response with increased volume while remaining hum-free—ideal for genres such as classic rock, blues, heavy rock, and metal.

Based on the popular Classic Stack but equipped with more power, the STK-J2B delivers a modern, more aggressive tone that cuts effortlessly through any band mix. Whether in the studio or on stage—this pickup makes your bass sing and rumble without losing any definition.

Seymour Duncan—Legendary Sound from California

For decades, Seymour Duncan has been the benchmark for high-quality pickups. Handcrafted in the U.S., their pickups combine classic tonal ideals with modern performance. The STK-J2B Hot Stack embodies this philosophy perfectly: vintage-inspired tone combined with the power and clarity that modern bassists need.

The use of Alnico V magnets gives the pickup a natural warmth and dynamic range, while the slightly overwound coil structure provides greater compression and output. The result is a tone that is both musical and powerful—with character and bite.

Technical Details of the Seymour Duncan STK-J2B Hot Stack Pickup

The STK-J2B is a stacked coil pickup in which two coils are arranged one on top of the other to eliminate the typical 60-Hz hum of conventional single-coil pickups. At the same time, the classic Jazz Bass format is retained, allowing the pickup to be easily installed in any standard bridge position—ideal for replacement or upgrade without modification.

With a DC resistance of 25 kOhm, the pickup delivers a medium-high output that’s perfectly suited for punchy basslines and aggressive playing. The wax-sealed construction protects against microphony and feedback, while the shielded 4-conductor connection cable allows for flexible wiring options—e.g., parallel connection, series operation, or coil splitting.

The housing is finished in classic black and blends discreetly with any bass design. The high-quality craftsmanship and meticulous sound tuning make the STK-J2B a reliable tool for bassists who want to get more punch and character out of their instrument.
