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. In the studio, this stack-style pickup bridges vintage Strat voicing with contemporary power, capturing definition across classic rock, country, and modern sessions while maintaining a focused, non-fatiguing presence in the mix.
Recording 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 ideal for tracking and layering. The wax-potted construction eliminates feedback and squeal, ensuring clean, reliable tracking at any gain setting during recording sessions.
Studio Design & Construction
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 sensitivity, translating to stronger signal capture and improved tracking definition. Tappable 3-conductor wiring enables quick switching between voiced configurations without rewiring, and USA manufacturing ensures consistent quality and reproducible tone session to session.
