Luthier's Digital Caliper

About This Item

Always one of our most popular items when we exhibit at luthiers conventions!

Our Luthier's Digital Caliper combines precision, ease of use, versatility and an attractive price, but its usefulness for fret work makes it special.

Customized for fretwork!
We added a custom jaw notch for accurately measuring fretwire crown height (the height above the fretboard). This is essential for comparing new wire to original wire. And thanks to a great idea by repairman Frank Ford, we've also added a notch on the depth gauge to measure fret height on the instrument—a real time saver.

  • Measures fret height before AND after fret installation
  • Accurate readouts in inches or millimeters
  • A must for all precision guitar work

Handy for lots of other measuring jobs in the shop—nuts, saddles, tuners, tool setups and more—this caliper has long-life stainless steel jaws. Featuring LCD digital readouts in inches or millimeters, it measures outside, inside and depth dimensions up to 6" (154mm), with super-accurate .0005" (.01mm) resolution. The jaws can be locked at any position.

LR44 battery and durable plastic storage case included.

You need this tool!

(Customer's Reviews)

What did I do without the luthier caliper? I cannot believe how often I reach for this tool now that I have it. My only complaint is that the case is difficult to open. It could be the arthritis in my hands. Definitely not a reason not to buy this tool. It's easy to use, easy to read and is dead on accurate. A must for any guitar workbench.


Great tool. Accurate.

(Customer's Reviews)

Accurate and cool features for measuring frets. A bit pricy but I am satisfied. I have to lock the jaws with its screw whenever I turn it off because it turns on esaily when unlocked (shortening the life of the battery). Plastic parts feel like weak but work fine.


I need a mechanical switch

Very good but battery life is too short.
