Seymour Duncan STK-S4m Stack Plus Strat Parchment Pickup
The STK-S4m Stack Plus is engineered to capture the open, articulate character of a vintage middle-position Strat while eliminating the 60-cycle hum that traditionally muddles single-coil recordings in tracking and overdub work. Hand-built in Santa Barbara with meticulous construction and wax potting, this pickup maintains the clarity and snap essential for punch-through middle-position tones on tape while staying dead silent under stage lights or studio hum. The parchment finish and RWRP configuration integrate seamlessly into classic Strat rigs, delivering authentic single-coil voice with modern noise rejection for clean, usable recordings across genres.
Tone & Electronics
Running 8.6k ohms of DC resistance with hand-ground Alnico V magnets, the STK-S4m produces a vintage output level that sits naturally between bright treble and warm midrange—ideal for tracking blues, classic rock, and traditional Strat voicing without excessive brightness or flabbiness in the mix. Wax potting eliminates microphonic squeal while preserving the articulation that defines great middle-position tone in the recording chain.
Design & Build
Constructed entirely in Santa Barbara from premium materials, this pickup features a 3-conductor shielded lead wire for splittable operation and traditional Strat mount compatibility. The RWRP (Reverse-Wound, Reverse Polarity) configuration pairs perfectly with standard-wound neck and bridge positions, canceling hum when blending pickup positions during layering and part stacking while maintaining individual pickup integrity in the session.
