10 Pieces Guitar Luthier Tools Set Include 9 Understring Guitar Radius Gauge and 1 String Action Gauge Ruler Measuring Tool Kit for Bass Setup(Silver)

Good set of gauges. I have bought something similar before but they stunk of machine oil and were super greasy. These, on the other hand, shipped clean and look to be cut well. 10 minutes with these and you can have your guitar dialed in.

Exactly what I needed to help me setup electric guitars. Looks good, seems to be good quality. The string gauge is easy to read. I use both of these tools on each guitar I work on.

If you set up your own instruments, you need these tools. I did not give them 5-stars because the alloy used is not the best quality. That does not effect the functionality but they feel cheap. You get what you pay for. Totally functional, low price, 4 stars

These are obvious crap. I am no luthier, but I play one in my bedroom. These did get the basic job of measuring done but let's not mix words - these are just junk stamped out of sheet metal. There is little to no accuracy here, don't expect much!Came across a Phantom acoustic on Facebook marketplace one day. Was really beat up, no strings, no pins, and even missing the nut! I bought all the parts on Amazon, just sticking to the best things I could get. This bone nut (had to shape it myself - a first for me!), new bridge and a set of D'Addario Silk and Steels. I didn't use the pins from this set though - found a set of Ebony ones instead.Wow - Phantom from back in the day - this thing sounds so rich and full - you wouldn't believe I bought it for $50. With early endorsements from Earl Slick of "Phantom, Rocker & Slick" this is a piece of music history. Thanks to Amazon for helping me out on this project!

Understring Radius GaugesI have basses with fretboard radii of 9.5", 10" and 12". In every case, the gauge that matched the instrument manufacturer's spec for fretboard radius was the closest to a perfect fit. Trying the 9.5" and 10" gauges on the 9.5" radius fretboard, for example, it was obvious the 9.5" gauge was the closest. None were exact but that could be because of my basses, not these gauges.String Action Gauge RulerNot very accurate. I measured several of the markings with digital calipers and some were short, some were right on, and some were long. The 3.5mm string height marking was actually 3.8mm, for example. It varies from scale to scale, and probably from ruler to ruler as well.There was plastic film on both sides of the ruler. After removing that I could see curved scratches on the face of the ruler, but they did not effect the markings. There was also a printing irregularity (ink splotch) on the back, but again not on any of the ruler markings so it doesn't affect functionality. The bridge saddle slot depth scale (inches) was printed too far from the edge, as was the 75mm scale on the back, making them both inaccurate from zero.For around ten bucks these should work for my personal use, but if I was making an instrument or charging someone to set up their instrument I would want something more precise like StewMac. Since I will be using these mostly as a first pass for string height, and then making minor adjustments to the action to suit my playing style, they should be okay. You get what you pay for.

Good value. I now play like Eddie Van Halen

This kit is awesome! At the price, I was doubtful, but this is legit. The action ruler took me a second but is my most preferred one I have used to date. Why? They use little white dots on the black surface for your measurements instead of just the black bar. This makes it far easier to actually tell exactly where the string height it, etc.The radius gauges feel solid and are in all of the standard sizes one would need.Extremely happy. Highly recommend.

This is my first time buying something like this. After struggling with getting the perfect string height on my guitar, I finally got this set of fret radius gauges and it has helped immensely!! I would highly recommend if your trying to get an accurate string height action on your guitar!
