10 Pieces Luthier Tools Include 9 Understring Radius Gauge and 1 String Action Gauge Ruler Measuring Tool for Guitar Bass Setup Repair Tools

The radius gauges are well made ,stamped out of sheet metal , they are well finished with no sharp edges . A good addition to the toolbox at a reasonable price. Thankyou.

These were perfect for setting the radius on a telecaster and string height gauge is easy to use and read.

They do the job but watch your guitar neck/body work when using. Edges are razor sharp.

Probably won't use the action measuring gauge as I prefer the more positive, 'feel' obtainable with feeler gauges, but looks good quality and, to the eye of an old engineer, quite accurate.Radius gauges much better than expected, particularly for the price. Can't vouch for accuracy (nothing to measure with) but modern manufacturing methods should mean this is pretty well spot on. Tiny edge burrs in a couple of places, but nothing that cannot be fixed with a fine file and certainly nothing to affect function or cut skin. Only couple of issues I have is that the 'handle' part of the tool could be a bit longer for me, as I no longer have the delicate dexterity of a younger individual, and the inner, corner radii (where handle meets bow) need to be a little sharper to avoid contact with strings. OK if you are very careful with positioning, but could give incorrect 'reading' if you don't pay attention. Again, an easy fix with a fine file.3* for Accuracy since I cannot measure this and 4* ease of use for reasons mentioned above.Maybe not good enough for professional use but for DIY maintenance (and at this price) hard to beat.

I assume the accuracy’s okay contrary to other reviews, it does look like it might be a little out but only fractionally - I still managed to adjust my string action and set up my guitar without any hassle and I’m certain it’s exactly the same as any other like-for-like product. My only issue with it is the markings on the tool look a little scratched up but can be overlooked due to the fact it carries out its intended purpose.

It helps you understand how to set your guitar up and it will help you in the long run

Easy to use.

Radius gauges are fine - checked on a couple of known radius fretboards and they are correctly marked up. The string height gauge is a bit rough in terms of the scales are hust printed on and don't all start at the edge! Ok for relative measurements, but maybe not accurate for absolute measurements.
