Seymour Duncan STK-S4m Stack Plus for Strat Black Pickup
The Seymour Duncan STK-S4m Stack Plus brings articulate, punchy mids with controlled output that cuts through in the middle position without crowding the stereo field. This passive pickup excels at capturing clean tones and light breakup with remarkable clarity, maintaining definition across a wide range of amp settings and gain structures. Hand-built in Santa Barbara using proven design principles, it’s the middle-position choice for tracking sessions and live work that demands balanced, responsive character.
Tone & Recording Performance
The 8.6k DCR and Alnico 5 rod magnets produce a focused midrange that sits naturally in a mix, with articulation that translates equally well to vintage-style clean recordings and moderate-gain overdubs. Wax potting eliminates feedback and microphonic noise, ensuring silent operation during tracking at any volume or monitoring level.
Design & Integration
Engineered as a reverse-wound, reverse-polarity (RWRP) design, this pickup cancels hum when paired with the neck or bridge position in standard switching configurations, reducing post-production cleanup work. The compact 0.995″ height fits standard Strat routs with no modification required, streamlining session setup and enabling fast instrument swaps.
