The Seymour Duncan Classic Stack Plus is a hum–cancelling bridge pickup designed to eliminate 60–cycle noise while retaining the tonal character of a traditional Stratocaster single–coil. Hand–tuned in the USA, this stacked–coil design delivers warm, bell–like response without the interference that plagues standard single–coils in high–gain environments or near lighting rigs. The STK–S4 uses a dual–blade construction that preserves string–to–string clarity while rejecting electromagnetic interference.
DC resistance measures 8.5k ohms at the bridge position, voiced slightly hotter than vintage output to cut through dense mixes without excessive compression. Alnico 5 rod magnets provide focused attack and enhanced treble articulation, maintaining harmonic complexity across the frequency spectrum. The pickup ships with three–conductor shielded cable for flexible wiring configurations, allowing series, parallel, or split–coil operation depending on switching requirements. Black covers match traditional Strat aesthetics while the stacked design fits standard single–coil routing without modification.
