Seymour Duncan SSB-4B Passive Soapbar 4-String Bridge Pickup
The SSB-4B captures articulate, punchy bass tone in the bridge position without requiring batteries or external power conditioning. Its moderate output and carefully voiced EQ curve deliver clarity and definition suited to tracking sessions where passive reliability and focused midrange presence matter. This is a direct replacement for EMG 35 cavity dimensions, making installation straightforward on compatible instruments.
Tone & Output Character
A 3.7 kOhm DC resistance with 8.1 KHz resonant peak produces focused midrange presence and controlled treble response. The EQ voicing of 6 bass / 4 mids / 7 treble emphasizes low-end definition while maintaining articulate attack—cutting through a mix with punch without muddiness in a passive platform, ideal for recording work across multiple bass styles.
Design & Compatibility
Dual blade magnets spanning the full coil length accommodate maximum string spacing up to 2.70″ (68.5mm), ensuring even response and consistency across all four strings during tracking. Ceramic magnet construction and dual-coil architecture provide the output stability needed for modern recording techniques, while the two-conductor cable simplifies wiring in any bass configuration.
