Seymour Duncan STK-S4m Stack Plus for Strat Black Pickup

Seymour Duncan STK-S4m Stack Plus for Strat Black Pickup

The Seymour Duncan STK-S4m Stack Plus delivers articulate, punchy mids with controlled output that locks into the middle position of your Strat. This passive pickup excels at clean tones and light breakup, offering clarity without harshness across a wide range of amp settings. Hand-built in Santa Barbara using proven design principles, it's the middle-position choice for gigging players seeking balanced, responsive performance on stage and in the studio.

Tone & Electronics

The 8.6k DCR and Alnico 5 rod magnets produce a focused midrange character that cuts through live mixes while maintaining articulation, working equally well for vintage-style cleans and moderate gain without losing definition. Wax potting eliminates feedback and microphonic noise, ensuring reliable, squeal-free operation at any volume during performances.

Design & Build

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, a critical feature for live reliability. The compact 0.995" height fits standard Strat routs with no modification required.
