Seymour Duncan STK-S9b Hot Stack Plus Strat Parchment Pickup

Seymour Duncan STK-S9b Hot Stack Plus Strat Parchment Pickup

The STK-S9b Hot Stack Plus is built for players who need aggressive output and articulate response that cuts through a live mix without sacrificing clarity. This bridge position pickup combines high output with the versatility of true single-coil splitting, making it equally reliable for hard rock, metal, and modern blues gigs. The distinctive parchment housing adds visual character while the patented stack design handles hum rejection without relying on heavy potting—essential for consistent stage performance.

Tone & Output Character

With a DC resistance of 20.26 kΩ and Alnico V rod magnets, this pickup generates substantial presence and sustain ideal for lead work and aggressive rhythm tones on stage. The 3.23 kHz resonant peak combined with an EQ curve of 5/7/4 (Bass/Mid/Treble) emphasizes midrange clarity and upper-mid punch while maintaining controlled low-end definition—keeping your tone defined and focused in a band context.

Design & Reliability

The patented Stack Plus design employs negative hum injection technology to eliminate 60-cycle noise without sacrificing the articulate single-coil character—a practical advantage for touring and venue variability. Each pickup is individually factory pre-tuned, and the three-conductor wiring enables easy conversion to true single-coil mode for tonal variety without rewiring.
