Seymour Duncan Set STK-S4 Black Cover / Classic Stack Plus Set Black P

Seymour Duncan STK-S4 Classic Stack Plus Set Black Cover Pickup

The STK-S4 Classic Stack Plus delivers the articulate, noise-free single-coil tones that cut through live mixes with clarity and snap. This set pairs traditional Strat voicing with intelligent hum-cancellation design, giving you vintage character and responsiveness on stage without the 60-cycle hum that undermines standard single coils in a band setting.

Tonal Character & Electronics

The neck and middle pickups voice at 5.7 kHz and 5.2 kHz respectively, capturing the articulate midrange and presence peak that lets your lines sit confidently in the mix. With a balanced EQ profile of Bass 5 / Mid 4 / Treble 8, these pickups emphasize clarity and definition while maintaining warmth; the Alnico V magnet and sand-cast Alnico 5 pole pieces ensure organic harmonic richness and responsive dynamics that translate well to live settings and recording.

Design & Specifications

Each pickup measures 0.995" (25.27mm) in height and fits standard Strat cavities without modification—no router work needed to get these installed. The middle pickup features Reverse Wind/Reverse Polarity (RW/RP) winding for automatic hum-cancellation when combined with the neck or bridge pickup, while three-conductor cabling allows splitting the middle pickup for true single-coil operation when you need maximum twang and aggression.
