Welcome to Spira Guitars!

Spira Guitars combines modern instrument design with performance-focused features for players seeking powerful sound and comfortable playability.

The Spira B-400 is a four-string electric bass built for punch, clarity, and modern performance. A roasted poplar body, a Canadian roasted maple neck, and a matching fingerboard are paired with custom Spira Villain Bass soapbar pickups, active electronics, and a fixed bridge.

The Finest Materials

The B-400 features a roasted poplar body paired with a Canadian roasted maple neck. Its Modern D neck profile offers a contemporary playing feel suited to precise rhythm work, technical runs, and melodic passages.

The Canadian roasted maple fingerboard features 24 jumbo frets and a 13.75-inch radius. Its two-octave fretted range on each string provides room for extended bass lines and upper-register playing.

A full 34-inch scale length and a 42 mm synthetic bone nut complete the specifications, while a dual-action truss rod allows adjustment of the neck relief.

High-Quality Hardware

Custom Spira Villain Bass soapbar pickups with ceramic magnets are paired with active circuitry to deliver tight lows, articulate mids, and a defined attack. Voiced for modern rock and metal, the B-400 offers a focused sound for dense arrangements.

One volume control and one tone control provide straightforward sound adjustment. The fixed bridge provides a practical platform for setup and string adjustment, while black-finished tuning machines and matching hardware complete the instrument’s design.

Shine on Stage

The B-400 combines a sleek design with a satin finish and black hardware for a clean, modern appearance. Its roasted maple neck and fingerboard create a coordinated wood aesthetic.

Whether you are locking in with heavy drums, recording detailed bass parts, or exploring melodic lines, the B-400 brings contemporary features and a focused voice to the stage and studio.

Standard Setup at Kairon Guitar Store

At Kairon Guitar Store, we understand the importance of receiving a bass that is ready to play. That is why we inspect and adjust each instrument before shipping, checking the details that contribute to its playability and performance.

Our Standard Setup includes:

• Visual Inspection: We inspect the instrument for visible defects and issues that may require attention.

• Tuning Machines: We check their operation and make adjustments as needed.

• Electronics and Pickups: We test the pickups and controls for proper operation.

• Neck and Frets: We examine the neck and frets and make appropriate setup adjustments.

• String and Pickup Height: We adjust the action and pickup height for balanced playability and response.

• Intonation: We adjust the intonation to help the bass play accurately across the fingerboard.

This service, normally valued at approximately $60, is included at no additional charge with your bass purchase.

Please note: Our standard setup does not include a string change. Please contact us for availability and pricing on replacement bass strings and installation.

For adjustments tailored to your individual playing style, string gauge, or preferred tuning, we recommend consulting a qualified luthier.
