What it does
- Includes 9 gauges from 7.25 to 20 inches so you can find your exact fretboard radius quickly
- Fits under strings and bridges, letting you match saddle heights to your neck arc for better playability
- Shaped with radiused surfaces on top and bottom so pickup polepiece heights align with your string curve
- Works on fingerboards and string spreads up to 2.625 inches wide, covering most guitar styles
Get your fretboard radius dialed in without guessing. You measure your neck, match your bridge saddles to that curve, and suddenly your action feels right and your intonation sits true.
This set gives you nine gauges in one pack. Each gauge has a curved edge on both sides, shaped to slide easily under your strings. The radii range from 7.25 inches all the way to 20 inches, so you cover vintage Fenders, modern shredders, and everything between. They work for any guitar with a string spread up to 2.625 inches wide.
Use them to check your fretboard radius, set bridge saddles, or match your pickup heights to the string arc. One simple tool does the job of a whole drawer full of gauges.
