Spira bass guitar with active punch and clear definition
The Spira B-400 MBK is a modern bass guitar for players who need to stay clearly audible in a dense mix. Its active Spira Villain soap-bar bass pickups with ceramic design give this 4-string tight low end, clear mids, and plenty of articulation, helping fast lines and heavy riffs hold their place in rock, metal, and other modern styles.
With a 34-inch scale, the B-400 MBK offers the familiar feel of a long-scale bass. The controls stay intentionally simple with one volume and one tone knob, so you can work quickly without unnecessary distraction.
Construction and playing feel of the B-400 MBK bass guitar
The body is made of roasted poplar and finished in Satin Black. That keeps the Spira B-400 MBK light in weight and gives it a clean, modern look that matches the black bridge, black machine heads, and other black hardware.
Roasted maple is used for both the neck and fingerboard. Combined with the Modern D neck profile, the approximately 13.75-inch radius, and 24 jumbo frets, you get a fast playing experience with full access to two octaves. The synthetic bone nut of approximately 42 mm and the dual-action truss rod complete the technical foundation. If you are looking for a modern bass guitar with direct response and an aggressive look, this Spira is a strong match.
Built for modern styles and tight bass parts
The sound character of the Spira B-400 MBK focuses on clarity, control, and punch. The low end stays tight, the midrange stands out clearly, and notes keep their definition, even when you play complex parts or fast runs.
With its fixed bridge and stable construction, this electric bass makes sense for bassists who want a direct, modern playing style. On stage, in the rehearsal room, or at home working out precise bass parts, this 4-string bass feels right at home.
