Key Features
The Spira B-400 MGR is a modern active four-string bass designed for players who need clarity, punch, and the ability to cut through a dense mix. Its roasted poplar body keeps the instrument lightweight while adding resonance and a focused low end that stays controlled, even at high stage volumes. The roasted maple neck and fretboard provide a smooth, stable playing surface with excellent note definition, making intricate runs and fast passages feel natural. Paired with a sleek Satin Black finish, the B-400 offers both contemporary style and real-world performance.
Custom Spira Villain active soapbar pickups supply tight, articulate lows, crisp mids, and an aggressive edge that works brilliantly for rock, metal, and high-energy modern styles. With 24 jumbo frets, you get full two-octave access for technical phrasing or extended melodic lines. Black hardware, a fixed bridge, and dependable machine heads ensure consistent tuning stability and intonation throughout long sessions and live shows. Whether you’re recording, rehearsing, or gigging, the B-400 is comfortable, punchy, and ready to deliver every time you plug in.

The B-400 is built around a roasted poplar body, offering an excellent balance of weight, resonance, and tonal focus. Roasting the wood removes moisture and increases stability, giving the bass a more responsive feel with improved consistency across the frequency range. This process also helps the instrument remain lightweight, reducing fatigue during longer sets or rehearsals while still delivering a punchy, controlled low end. Players who value comfort without sacrificing tone will appreciate how naturally the bass sits against the body.
The roasted maple neck and fretboard contribute not only to the instrument’s sleek aesthetic but also to its stability and clarity. The Modern D shape provides a familiar, comfortable grip that suits a wide range of techniques, from fingerstyle to fast pick work. Its 24 jumbo frets and 13.75-inch radius give you room to explore the full two-octave range with accuracy and ease. Roasting the maple increases its structural integrity, helping the neck withstand climate changes and busy gig schedules.
At the heart of the B-400 are its custom Spira Villain active soapbar pickups. Voiced with ceramic magnets, they deliver the tight, articulate lows and pronounced midrange needed to stand out alongside loud guitars and powerful drums. The active circuit keeps the output clean and punchy, ensuring your tone stays defined even at higher gain levels. Whether you prefer aggressive modern bass sounds or cleaner classic tones, the electronics provide a versatile foundation.
The B-400’s hardware is designed to offer consistent performance in demanding environments. The fixed bridge enhances sustain and keeps intonation locked in, while the black machine heads provide solid tuning stability. The satin finish feels smooth to the touch and reduces glare under bright stage lights. Combined with the dependable dual-action truss rod and sturdy construction, the instrument is engineered to handle rehearsals, recording sessions, and live shows with ease.
