Roasted wood construction
The Spira S-420 is built using carefully selected roasted tonewoods, ensuring not only a visually appealing instrument but also one that performs with strength and consistency. The roasted poplar body enhances the guitar’s overall resonance and responsiveness, giving each note a more balanced tonal character. This treatment also reduces the wood’s moisture content, increasing its resistance to changes in humidity and temperature—ideal for touring musicians who need reliability wherever they play.
Complementing the body is a Canadian roasted maple neck, which delivers a snappy attack and excellent sustain. The roasting process strengthens the neck, making it less susceptible to warping over time. From rehearsing, recording, or performing on stage, the S-420’s roasted construction ensures your tone stays consistent and your instrument stays solid.
Sleek and smooth playability
Playability is at the heart of the S-420’s design. The Ebony Tech fretboard is engineered for a fast, fluid playing experience. With 24 jumbo frets, you get plenty of space for expressive bends, technical riffing, and comfortable access across the entire neck. The smooth finish on the fretboard provides just the right amount of glide, reducing friction while enhancing precision during complex runs or aggressive chording.
Its modern D-profile neck ensures ergonomic comfort, perfect for sweeping through solos or laying down tight rhythm parts. Designed with versatility in mind, the neck shape suits a wide range of techniques and styles, giving you full command over your performance without fatigue.
High-output Villain humbuckers
At the core of the S-420’s sound are its dual Spira Villain™ humbuckers—powerful pickups designed for high-gain dominance. These pickups bring a formidable combination of output and articulation, ensuring every note remains clear and focused even in the most saturated distortion settings. If you’re chugging low-end riffs or soaring through lead lines, the Villain pickups respond with punchy dynamics and exceptional clarity.
Perfect for modern metal, hard rock, and progressive styles, they handle everything from tight rhythms to ambient cleans. You can rely on their consistency across different amp and pedal setups, making them a go-to choice for both stage and studio use.
Locking tremolo and stage-ready hardware
One of the standout features of the S-420 is its locking tremolo system. Designed for expressive play, it allows for aggressive divebombs, fluttering vibrato, and pitch shifts without sacrificing tuning stability. Unlike traditional tremolos, the locking design ensures that your strings return to pitch accurately after every move, making it a must-have for any performance that demands precision.
Backing this up are reliable locking tuners and rugged black hardware, offering both visual edge and practical function. The combination of hardware ensures long-lasting tuning accuracy, excellent intonation, and seamless setup changes. Together, these features make the S-420 AWH a powerful, road-ready machine that’s just as dependable in the studio as it is under the stage lights.
