Seymour Duncan SSL-4 Quarter Pound Flat For Strat Pickup

The SSL-4 Quarter Pound Flat delivers a muscular, punchy character that sits between vintage warmth and modern aggression. This single-coil replacement maintains the classic Strat snap while adding substantial output and midrange presence, making it ideal for players who want more cut and sustain without sacrificing the instrument's inherent brightness and articulation.

Tone & Electronics

Built with 0.25" Alnico V rod magnets and hand-wound, wax-potted construction, this pickup produces a tight, focused frequency response with a resonant peak at 4.4 kHz (full coil) that emphasizes punchy mids and presence. The EQ balance of 5/4/6 (Bass/Mid/Treble) keeps the low end controlled while pushing articulate upper-midrange detail, ideal for rock, blues, and high-gain applications.

Design & Build

The modern oval Forbon flatwork with flat, same-height pole pieces ensures consistent string response across all six strings and resists the microphonic feedback common in vintage designs. Hand-dipped lacquer bobbins provide durability while maintaining traditional manufacturing quality, and the single-conductor PVC cable integrates cleanly into most Strat wiring schemes.
