Neck Production
Neck Production

We offer detailed customization of necks, such as grip shape, wood selection, head shape, scale length, and inlay design.
Thanks to our full-order production system, we can tailor the neck to suit your preferences, including the “feel” and playability you value most.
We also provide neck replacement services for guitars and basses from other manufacturers.
Features

Wide Range of Material Options
We can craft the neck to your desired specifications, including neck wood, fingerboard wood, nut material, fret wire, and other components.
We can also replicate the shape of a previously used neck with a “custom grip” option.

Free Design Options
You can choose your own original headstock shape.
Additionally, we offer visual customization options such as matching headstock colors to the body, color rings, bindings, and original inlays—allowing you to fully express your personal style.

Down-Tuned Scale Lengths
Our half-step to two-step down-tuned scale options allow you to lower the tuning simply by slightly shifting the capo position—no need to adjust the tuning itself.
This feature is especially popular among technical players, as it significantly reduces the drawbacks of down-tuning.

Thermo Wood
Thermo wood is one of our signature materials.
Its biggest advantage is its exceptional stability.
It is minimally affected by seasonal changes or humidity, allowing your instrument to maintain ideal setup conditions over the long term.

Carbon Neck
By using a hollow construction, the neck is designed to resonate softly and clearly—just like wood.
It is completely unaffected by changes in climate, allowing you to maintain optimal neck conditions and perform without compromise.
Additionally, like wooden necks, a truss rod can be installed to enable adjustments to neck relief and string height according to the player’s preference.
