FretGuru 8-in-1 String Action Gauge Guitar Fret Ruler Precision Fret Rocker - Precise CNC Machined, Diamond Honed, Polished Edge Guitar String Height Gauge - Luthier Tool with Thick Leather Case

Arrived fairly quick the leather case is a lovely touch think I will definately get a imperial one too in the future

I've got other similar tools, but I've always found them hard to get accurate measurements of the string action height. This isn't the case with the FretGuru2, it's a lot easier to see exactly how high the action isI've not really much use for the other features at the moment, although the fret height guage could be useful, although probably more so for a tech than an enthusiast user, that said, my new (to me) guitar had rather low frets, which would have been easier to measure with this tool rather than digital callipersThe fraction/decimal/metric conversion chart on the back is a nice touch and will save a lot of messing around with google trying to figure out metric measurements from fractions of an inch

Great tool, helpful conversion chart on the back. I don’t go a day without using it on my work bench.

A very well designed quality measurement tool for all fret and nut set-up jobs. Bought this to help final adjustment of a replacement nut on a mandolin - a unique feature allows string slot depth assessment. The metric version is particularly good value - economical and quick US to UK import.

Ok

High quality gauge well worth the extra money compared to the cheap Chinese made ones

I used to think a gauge was a gauge but that is not true - this is superior in every way even down to the colour which I found much easier to see the strings contrasted against!! The markings on this gauge don't wear or rub off and make for much more accurate readings. The nut height and fret height measures are excellent additional tools that put the mighty Stewmac's gauge in the shade! Love the polished edges which prevent any unintentional nicks and the leather case to keep it in A1 shape in my setup box.
