The quiet satisfaction of a perfectly set-up instrument begins with precision. This kit brings professional-grade measurement tools to your workbench, allowing you to fine-tune the geometry of your guitar with confidence.
Designed for technicians and dedicated players, these tools help adjust bridge saddles to match the fingerboard radius, ensuring smooth playability across all strings.


02MATERIALS
Stainless steel construction for lasting accuracy
Each gauge is machined from stainless steel, offering a rigid and corrosion-resistant surface that holds its shape over time. The material choice ensures that the critical radii remain true, providing consistent reference points for every adjustment session without warping or wearing down.
