Seymour Duncan STK-S4 White Cover Classic Stack Plus Pickup Set

The STK-S4 Classic Stack Plus delivers articulate, noise-free single-coil tones with the muscle of a humbucker's output. These stacked pickups sit flush in standard single-coil routes, offering tight highs and punchy mids without the hum that plagues vintage designs. Hand-built construction and vintage-inspired voicing make this set ideal for players seeking authentic Fender-style character with modern reliability.

Tone & Resonance

The Alnico V rod magnets and carefully tuned resonant peaks—5.7 kHz at the neck/mid position and 5.2 kHz at the bridge—produce clarity and definition across the frequency spectrum. An EQ curve of 5/4/8 (Bass/Mid/Treble) balances warmth in the low end with crisp, articulate highs, making these pickups equally comfortable for blues, classic rock, and vintage pop.

Construction & Design

Each pickup is wax potted to eliminate microphonic squeal, ensuring rock-solid stability during high-gain passages or clean tones alike. The included three-conductor cable allows true single-coil splitting, expanding tonal palette without requiring additional modifications. Hand built in Santa Barbara, CA, these pickups maintain exacting tolerances and premium materials throughout.
