What does 'passive' mean, and why would I choose passive over active?

Passive means no batteries required—the pickup operates solely from the bass's natural signal. The SSB-4B delivers active-style clarity and punch without the maintenance burden, making it reliable for gigging and recording sessions where battery failure is a risk.

Will this pickup fit my bass?

The SSB-4B is a direct replacement for EMG 35 cavity dimensions and accepts strings spaced up to 2.70 inches (68.5mm). If your bass currently houses an EMG 35 or has an EMG 35-sized pocket, installation is straightforward; otherwise, routing may be needed.

What kind of tone will I get?

Expect articulate attack, focused midrange presence, controlled treble, and punchy low-end definition without muddiness. The 3.7 kOhm DC resistance and 8.1 kHz resonant peak are voiced for funk, jazz, and studio clarity rather than heavy metal aggression.

Is the SSB-4B good for metal or drop tunings?

No—the pickup's tonal character and moderate output are optimized for articulate, defined playing styles like funk and jazz. Metal and drop-tuning players typically benefit from higher-output, darker-voiced pickups.

What's included, and what do I need to install it?

The pickup comes with a two-conductor cable for straightforward wiring in any bass configuration. You'll need soldering skills and basic bass electronics knowledge, or a qualified technician, to complete the swap into your EMG 35 cavity.

Do I pay sales tax on this order?

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.
