Spira B-400 MBK Satin Black

The Spira B-400 is a modern four-string active bass built for punch, clarity, and real-world performance. Designed to cut through loud guitars and heavy drums, it delivers a focused, controlled low end that stays present in even the densest mix.

A roasted poplar body keeps it lightweight and resonant, while the roasted maple neck and fretboard provide a comfortable, fast, stable feel with excellent note definition. With 24 jumbo frets, players have full two-octave range for technical runs, precise phrasing, and extended lines.

Powered by custom active Spira Soapbar pickups, the B-400 delivers tight lows, articulate mids and an aggressive attack without unwanted mud, ideal for rock and metal tones.

Its sleek design and precision hardware ensure dependable tuning stability and intonation, making the B-400 a reliable choice at home, on stage, or in the studio.
