Welcome to Spira Guitars!
Spira Guitars combines modern instrument design with performance-focused features for players seeking powerful sound and comfortable playability.
The Spira S-420 builds on the S-400 platform with a locking tremolo system for expressive pitch control. A double-cutaway roasted poplar body, a Canadian roasted maple neck, and an Ebony Tech fingerboard are paired with custom Spira Villain™ humbuckers and black hardware.
The Finest Materials
The S-420 features a roasted poplar body paired with a Canadian roasted maple neck. Its Modern D neck profile and satin neck finish provide a smooth, comfortable playing feel for rhythm work and lead passages.
The Ebony Tech fingerboard features 24 jumbo frets and a 14-inch radius, providing a relatively flat playing surface for chord work, string bends, and technical passages. A 25.5-inch scale length and a 43 mm locking nut complete the specifications, while a dual-action truss rod allows adjustment of the neck relief.
High-Quality Hardware
Custom Spira Villain™ humbuckers with ceramic magnets deliver powerful, articulate tones suited to rock, metal, and high-gain playing. The HH configuration provides hum-canceling performance, while one volume control and one tone control allow straightforward adjustment of output and tonal character.
A Korean-made Sung-il locking tremolo bridge works with the locking nut to support tuning stability during expressive tremolo use. From subtle vibrato to dramatic dive bombs, the system expands the guitar’s range of performance techniques. Black-finished tuning machines and matching hardware complete the design.
Shine on Stage
The S-420 combines a double-cutaway silhouette with a gloss body finish and black hardware for a clean, modern appearance. Its roasted maple neck and dark Ebony Tech fingerboard add contrasting tones to the overall look.
Whether you are playing heavy riffs, exploring intricate solos, or adding dramatic tremolo effects, the S-420 brings contemporary performance features to the stage and studio.

Standard Setup at Kairon Guitar Store
At Kairon Guitar Store, we understand the importance of receiving a guitar 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 guitar play accurately across the fingerboard.
This service, normally valued at approximately $60, is included at no additional charge with your guitar purchase.
Please note: Our standard setup does not include a string change. D’Addario XL Series strings are available at an additional cost. Please contact us for pricing on replacement strings and installation.
For adjustments tailored to your individual playing style, string gauge, or preferred tuning, we recommend consulting a qualified luthier.
