Luthier tool kit designed for accurate fingerboard radius measurement and saddle-height adjustments, the Tanstic Understring Radius Gauge Kit includes nine understring radii and a 32-blade feeler gauge. Confidence and speed during setups reduce rework and improve playability for guitars and basses. Is this compact set the right choice for hobbyists and workshop technicians?
⚡ At a Glance
- • Measuring Accuracy: Matches common fingerboard radii with dedicated understring gauges
- • Best for: Luthiers, technicians and keen players who perform regular setups
- • Not ideal for: Users who need electronic measuring tools or integrated digital readouts
Nine understring radius gauges cover popular fingerboard curvatures and a foldable 32-blade feeler gauge helps set saddle height. Made from metal with smooth edges, the gauges are rust and corrosion resistant and marked in both metric and imperial units.
Accurate fingerboard profiling - with nine understring radius gauges
Each understring gauge corresponds to a specific radius, including 7.25", 9.5", 10", 12", 14", 15", 16", 17" and 20". Use the bottom radius of a gauge to measure from above or below the strings and compare the top radius to identify the correct match.
Quicker, repeatable detection of fingerboard curvature reduces guesswork during fret dressing or neck adjustments. Matching radii helps achieve consistent string action and better intonation.
Precise saddle height checks - with a 32-blade feeler gauge
The foldable feeler gauge contains 32 blades for a broad range of gap measurements. Double marking in metric and imperial simplifies choosing the correct blade for tiny clearance checks.
Fine, incremental checks of saddle height speed up bridge setup and ensure accurate string height across the neck. The foldable format keeps blades protected and easy to carry between jobs.
Durable, workshop-ready construction - with corrosion-resistant metal and smooth edges
Gauges are manufactured from sturdy metal with smooth, burr-free edges and treated to resist rust and corrosion. Compact, lightweight design enables storage in a toolbox or gig bag.
Tools tolerate regular workshop use without easily breaking or dulling, making them reliable for frequent setups. Safe edges and corrosion resistance improve longevity and minimise the need for frequent replacement.
