FretGuru 8-in-1 Precision String Action Gauge for Guitar Setups (Inch or Metric+)

$25.87

The hyper accuracy of the second edition FretGuru 8-in-1 Precision String Action Gauge will help you bring your guitar into another world of playability that’s measurably unmatched.

Here are the highlights:

  • Precise String Action Rulers for 0.010” (ten thousands of an inch) or 64th” (1/64ths on an inch) measurements — including halved measurements!

  • Laser-etched markings deep through the durable, anti-glare-coated black finish and metal mean supreme readability with no printing to rub off.

  • Microscopic flatness on three sides ensures precise measuring — you can even use it as a fret rocker in a pinch — thanks to being individually laser cut, CNC machined and then diamond honed and polished.

    • Also ensures our gauge is less likely to scratch guitars thanks to a silky smooth finish (no belt sander marks here!).

  • Made of high-quality stainless steel and engineered from the ground up as a precision measuring and evaluation gauge (not just an imprecise metal business card like many competitors).

  • Shop Rule / Depth Gauge function for up to 2 1/4” / 16mm for everything from pickup height to string spread.

  • Fret Wear Depth Notches help you quickly decide on just a setup or more advanced fret leveling without specialized calipers.

    • Also great as a Fret Height Checker!

  • Extra-thin Nut Slot Height measuring edge lets you rest the gauge in any nut slot (as small as the high e-string, .010”) and on the second fret, so you can glide feeler gauges under the 1st fret.

    • This helps you avoid tone-killing fret buzz and notes that pull sharp on the fret few frets.

  • Inch/Metric Conversions on back to save you time when working between SAE and metric parts.

  • Exceptionally comfortable to hold thanks to front-to-back beveled edges and rounded corners.

  • Includes durable, handmade leather protector sleeve.

  • Precision crafted in the USA.

  • Also available in Metric+ version.
