Seymour Duncan SSB-4S Passive Soapbar 4-String Pickup Set

Seymour Duncan SSB-4S Passive Soapbar 4-String Pickup Set

The SSB-4S delivers articulate, controlled output with ultra-low noise—ideal for bass players who demand clarity without the complexity of active electronics. These passive humbucking soapbars retain the aggressive character of the original design while offering a direct drop-in solution for EMG 35 or 40 equipped instruments.

Tone & Electronics

Ceramic bar magnets paired with two-conductor wiring produce moderate output with exceptional noise rejection, making these pickups equally at home in studio tracking and live performance. The calibrated neck and bridge set exhibits different resonant characteristics—9.2 kHz at the neck and 8.1 kHz at the bridge—to maintain balanced response across the fingerboard.

Design & Compatibility

Full-length dual blades accommodate maximum string spacings up to 2.70" (68.5mm), ensuring proper pole piece alignment regardless of bridge configuration. Passive construction eliminates battery requirements and the maintenance concerns associated with active systems, while the soapbar form factor integrates seamlessly into any compatible cavity.
