Seymour Duncan STK-S6 Custom Stack Plus, Black Pickup

The STK-S6 Custom Stack Plus delivers articulate, responsive single-coil character with modern output and clarity. On stage and in the studio, this stack-style pickup bridges vintage Strat voicing with contemporary power, sitting well in classic rock, country, and modern styles that demand cut and definition without harshness.

Tone & Output Character

Built with Alnico 5 rod magnets and symmetrically staggered, sand-cast Alnico 5 pole pieces, this pickup produces punchy midrange presence and articulate treble response. The wax-potted construction eliminates feedback and squeal, ensuring clean operation at any volume—critical for reliable gigging and live reliability.

Design & Build Quality

Standing .995" (25.27mm) tall—.175" (4.45mm) taller than a vintage pickup—the STK-S6 Custom Stack Plus sits closer to the strings for enhanced output and sensitivity. Tappable 3-conductor wiring enables versatile switching options for different tonal voices on the fly, and USA manufacturing ensures consistent quality and materials sourcing you can count on night after night.
