Seymour Duncan STK-S4b Stack Plus for Strat Black Pickup

Seymour Duncan STK-S4b Stack Plus Bridge Pickup – Black

The STK-S4b Classic Stack Plus delivers articulate, chimey output with impressive dynamic response for a stacked single-coil design. This bridge-position pickup balances clarity with authority, cutting through a mix without sacrificing the vintage character that defines classic Strat tones. Hand-built in Santa Barbara, it's engineered to capture controlled treble presence and snappy articulation—essential for bridge tones that sit well in dense mixes and respond transparently to your playing dynamics.

Tone & Output Characteristics

A 10.36 kΩ DC resistance and 5.2 kHz resonant peak deliver bright, defined highs with controlled midrange—ideal for lead lines and articulate rhythm parts that need to punch through without muddying adjacent tracks. The EQ curve of 5 bass / 4 mid / 8 treble pushes presence without harshness, making this pickup responsive to picking dynamics and effective across the gain spectrum from clean recordings to light overdrive, where it maintains note definition and separation in multi-track sessions.

Construction & Winding Specifications

Built with Alnico V rods and sand-cast, symmetrically staggered Alnico 5 pole pieces, this pickup maintains even response across the string spread—critical for consistent tracking and balanced string-to-string output during recording. Wax potting eliminates microphonic feedback, ensuring clean operation without squeal—a necessity in studio work where unwanted noise can compromise takes and complicates mixing.
