Guitar Neck Relief Gauge with Digital Display for Fingerboard Straightness

This instrument tool uses a long silver metal bar with a central digital gauge, creating a stable layout for precise measurement during repair work. As a measuring gauge, it is designed to check guitar neck relief, fingerboard straightness, and bridge height with a single setup. The compact round display, top contact point, and small control buttons make this guitar neck gauge easy to read and operate in close workspace conditions. Adjustable support feet underneath help position the guitar setup tool securely against the instrument surface for more consistent readings. As a neck relief gauge, it supports setup and maintenance tasks by helping identify curvature and straightness issues that affect playability.
