What makes the STK-J2B different from the standard STK-J1?

The STK-J2B is the hotter, high-output bridge model designed for aggressive playing styles and cutting through louder mixes. It features a higher DC resistance (25.2 kΩ) and a 5.5 kHz resonant peak that emphasizes definition and punch over warmth, compared to the standard J1 voicing.

Will this pickup eliminate hum and feedback?

Yes. The dual stacked coils provide hum-cancellation, and vacuum wax potting eliminates microphonic feedback for long-term stability. This design makes it suitable for live performance and studio work without unwanted noise.

Is this compatible with my four-string Jazz Bass?

The STK-J2B is designed as a bridge-position pickup for four-string Fender American Standard Jazz Bass models. It measures 3.730" × 0.741" and includes a standard four-conductor cable for flexible wiring. Verify your bass's pickup cavity dimensions before ordering.

What kind of tone should I expect?

Expect bright, focused tone with high output and pronounced midrange cut—perfect for funk, jazz, and modern styles where clarity and aggressive punch are priorities. The 5.5 kHz peak delivers tight articulation and definition suited to cutting through a mix or driving tube amps hard.

What's included in the box?

The pickup comes with a four-conductor hookup cable and a logo cover, giving you everything needed for installation.

Tone & Output Character
