Precise string action gauge in .010" (ten thousandths of an inch) number increments, and .005" line increments = super accurate guitar setup! The markings are NOT printed - they are actually laser etched through the black surface, deeply into the stainless metal. No printing to rub off! Also check out the new, precision 64ths string action gauge. The accuracy of the FretGuru 2 will bring your guitar out of the realm of woodworking and into another world of playability.
✓
Unique, first of it's kind fret height/fret wear gauge in .005" increments. No more fumbling with calipers, straightedges or feeler gauges.
✓
Fret rocker! The 3 unequal length sides are CNC machined, precision diamond honed and polished. Now you can find that pesky high fret without scratching your frets.
✓
Another first - the uniquely designed Nut Slot Height gauge, which has already been a massive time-saver here on the workbench. <br>You’ll notice the silver square on the bottom corner of the gauge. This corner is designed and engineered to be just under .010” thick, which allows it to slip into each nut slot - including the narrow high e slot.
✓
Simply rest the thin corner into the bottom of each nut slot - and the other end across to the 2nd fret, then measure the gap as the gauge passes over the 1st fret. It's never been easier to zero in on the perfect string height as it leaves the nut. <p>Also, be sure to check out the separate listing for the sweet handmade custom leather case!
