WELIGHT Guitars began with a simple assumption. Lighter materials would create a lighter guitar.
In 2015, we built our first aluminum prototype. It was unexpectedly heavy. We then tried stainless steel. The result was nearly identical—around 5kg. That was when we understood: Weight is not defined by material alone.
In 2017, after introducing welding technology, we redesigned the structure itself. The weight dropped dramatically to around 2.2kg.
At the same time, our understanding of aluminum evolved. Initially, we painted it. But we realized aluminum was not something to hide—it was something to express. We transitioned to anodized finishes, allowing the material itself to define both texture and color.
But solving weight revealed a deeper challenge. Sound.
We began experimenting with neck materials. Softer woods provided stability, but lacked clarity. Harder woods improved tone—but introduced new risks. In 2021, a prototype shipped to Europe arrived with a broken neck. In 2022, another arrived twisted due to the natural behavior of wood.
Despite these failures, one fact became undeniable. A stiffer neck produces a stronger, more defined sound. Around this time, we had the opportunity to place our instrument in the hands of a world-class guitarist. His response was simple: "The tone is solid. It's very defined." This confirmed our direction.
In 2023, we turned our focus inside the instrument. We discovered that the aluminum cone and aluminum body were resonating at similar frequencies, causing vibration to disperse throughout the entire structure. Energy was being lost. So we redesigned the internal structure. Not to increase resonance— but to control it.
We also made a counterintuitive decision. We reduced the size of the body. By minimizing internal space, we limited how vibration could disperse, increasing density and forward projection. Less space. More focus.
Finally, in 2025, we re-engineered the neck. By combining laminated bamboo with Richlite, we achieved both rigidity and stability. We also introduced CNC machining for the neck and fingerboard. Not for mass production— but for precision. Every angle, every surface, every contact point is engineered to ensure consistent vibration transfer.
For the first time, we were able to control the flow of vibration across the entire instrument. From the cone, through the body, into the neck.
This is not just a lightweight guitar. It is a system engineered to control sound.

About This Model / このモデルについて
Shine features a 12-fret neck joint that gives the instrument a distinctive classical appearance and tonal character. This traditional design shifts the bridge position toward the center of the body, producing a warm and rich resonator response. Combined with WELIGHT's lightweight aluminum construction, Shine blends vintage-inspired aesthetics with modern precision. It is an ideal model for players who appreciate a classic look with the clarity and projection of a modern resonator.
Shineは12フレットジョイントを採用したモデルで、クラシカルな外観と独特のサウンドキャラクターを持っています。この構造によりブリッジ位置がボディ中央寄りとなり、より豊かで深みのある響きを生み出します。アルミニウムボディによる軽量設計と精密構造を組み合わせることで、クラシックな雰囲気と現代的な演奏性を両立しています。
