Seymour Duncan Quarter Pound Jazz SJB-3S Pickup Set

The SJB-3S Quarter Pound Jazz set delivers articulate, warm tones with punchy midrange character ideal for jazz, fusion, and vintage-voiced applications. Hand-built in Santa Barbara with Alnico 5 magnets, these pickups offer clarity and sustain without excessive output, making them a refined choice for players seeking definition over raw power.

Tonal Character & Specifications

Moderate output at 13.7 kΩ (bridge) and 13.3 kΩ (neck) provides controlled response across the frequency spectrum while maintaining excellent note articulation. The wax potting eliminates microphonic feedback, ensuring clean operation in both studio and live settings.

Construction & Engineering

These pickups employ quarter-inch diameter Alnico 5 rod magnets paired with Forbon flatwork for consistent pole piece alignment and reliable performance. The neck pickup features reverse wound/reverse polarity (RW/RP) configuration to achieve hum cancellation when both pickups are engaged together.
