String Radius Gauge and Fingerboard Measuring Tape for Guitar Quickly measure and match the radius of a fingerboard or strings to make accurate setup and decisions. This compact gauge is designed to simplify neck and bridge work, helping you check curvature, compare parts, and confirm adjustments with confidence. Key benefits Identify the correct fingerboard radius before refretting or replacing a bridge saddle, reducing trial and error. Match bridge saddles and string contact points to the neck radius for even string action and consistent playability. Speed up setups and diagnostics by giving clear, repeatable radius readings across the fretboard. Product highlights Function: Measures fingerboard radius and helps align string contact and bridge geometry during setup and . Compatibility: Suitable for electric and acoustic guitars, basses, and most fretted instruments where radius measurements are required. Size and format: Compact, easy to carry and store; designed to lay on frets and conform to the fingerboard curve for practical oninstrument use. Material and markings: Constructed from durable, flexible material with clear, easytoread graduations for reliable visual comparison during measurement. Performance: Allows fast visual verification of radius at multiple points along the neck to spot variations, verify modifications, or confirm factory specifications. Practical use scenarios Setup and intonation: After adjusting saddle height or replacing a bridge, use the gauge to match the saddle curvature to the fingerboard so strings sit evenly across all strings. Fretwork and refretting: During fret dressing or when installing frets, verify the restored radius to ensure consistent string action and minimize buzzing. Diagnostics and : Check for neck twist or uneven fretting by measuring radius at several positions from nut to heel to find where adjustments or shimming are needed. How to use Lay the gauge along the fingerboard so it rests on the frets or over the strings. Compare the curve of the gauge to the fingerboard surface to determine the closest match. Use readings to guide saddle shaping, fretboard profiling, or bridge setup. This practical measuring tool provides a simple, reliable way to confirm fingerboard curvature during maintenance and tasks, improving the accuracy and consistency of guitar setups.
