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

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).

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.

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.

If you build guitars, you will need a set of radius gauges to set the fretboard curve. If you don't have a set, these are a good buy and, after checking the radius against curves drawn with a compass, they appear to be accurate. They are made of metal and are stiff. Naturally, they are marked with the radius and have a hole in the handle so they can be hung on pegboard. Recommended.

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.

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.

I bought these radius gauges from Big Teddy because he had the best price on Amazon! I read lots of reviews stating that when others bought these types of gauges that they had to sand the edges because they were sharp and could damage the finish on a guitar!! Not so with these they were perfectly milled and rounded properly so I didn't have to sand anything :) Big Teddy has great prices, good quality merchandise and superfast free shipping! I will definitely buy more items from him and I highly recommend him without hesitation!
