BIGTEDDY - Set of 9 Understring Radius Gauge for Guitar and Bass Setup Luthier Tools for Bridge Saddle Adjustments

Pretty pretty pretty goodScratching my head how they got so many sissies on here crying about the little sharp edges. Weak.Like one of them had a little bit of sharpness that I sanded down with my fingertipsThis is pretty good for the money

This set of under string radius gauges are great for setting up my tele and strat bridge saddle heights. Definitely solid and seem well made. The metal seems like fine stainless steel and they're strong and did not bend at all. The edges were not really sharp. Although, be careful anyway if you don't know what radius your fretboard is and check it at the fret board, it might make some small micro scratches on the wood because it's just metal on wood.The radius of each gauge is imprinted into the metal and completely legible. I am very satisfied with this inexpensive set. I needed three of the gauges for different guitars and now they feel better than ever. Definitely a must if you want to do your own setups and have any f nder type guitar bridges with 6 or 3 independent adjustable saddles.

These radius guages were relatively inexpensive for what they are used for. They appear to be accurate. One thing I noticed was the edges are sharp and will need to be lightly sanded with some fine sandpaper used for metal. I had read about this in previous reviews of this product so it was the first thing I checked so I would not injure any of the guitars I might use them to check the string radius. For the price they were purchased for I figured a little bit of time spent prior to use would be well worth the savings. If the edges had already been smoothed over to remove or reduce those sharp edges, I would have rated them with 5-stars.

As you see in my photos I did a similar test as other guy that said these are off. These are so light it'd be easy to slightly skew the radius when pulling the tool up for this demonstration and prone to human error. As carefully as I could I traced top, then pulled straight up. It was flush!For the price these are great. They can feel a little sharp but nothing that will actually cut you. I used it to set strings on two basses and they sound great (tested tool accuracy on 3 though).

I really haven't used them yet so all I can say is that to me these seem well made and they don't have sharp edges. If you are going to setup your guitar, you should have this tool to help setup the bridge.

They do what they are supposed to do, I’m sure there are better to be had but these put up against more expensive gauges found no real difference, you may want to sand some adhesive down with 600 git to soften up some corners but they are true to size and work well with checking guitar radiuses and adjusting string heights.

These gauges are accurate for sure, but the stamped metal edges risk maring the finish on the guitar neck and that is simply unnecessary. I know they are all of $9, but it takes nothing to hit them on a wire wheel to ease the edges. So, would you rather pay $9 for radius guages or upwards of $800 plus to refurbish a clients vintage Telecaster? You tell me.

As I do my own guitar setups and have made acoustic guitar saddles, these gauges are handy. When checked against a set of fret board radius gauges, they match perfectly. Although they are under string gauges, the opposite surface can be used to check fret board radius or over string radius. These gauges are a bit rough around the edges, but for the relatively low price, they are good value.
