Luthier Understring Radius Gauge 9 Set

I bought these to properly set up my Fender Strat, which has a 12" radius. This finished the set up to perfection, and the guitar plays better than it has ever done. As they come in a set, there is a gauge for every possible neck. all on a handy key chain. A quality product, which I would recommend.

I’ve yet to use this properly, but I’m pleased to see that it looks solid and the edges are quite smooth so it shouldn’t scratch anything. Nice and thick - doubt it will bend out of shape easily. Looks well-made. Both top and bottom are curved, so should be easy to check neck radius.

A good set with all the radii that I can imagine needing. The metal is quite a bit thicker than I expected, so they should last well. I can't vouch fro the accuracy of each gauge, but the ones I've checked against known fretboards seem good. Essential for setting up bridges and pick up pole pieces.

Well made, with no sharp edges. Nice thickness and Don't bend with normal use. Came on a handy key ring. Great value for money. Would by from Spartan music again if I saw something I needed.

these are great. A good set, easy to use and more versatile than over-string ones I've tried. Well made, no sharp edges. Happy with these. They come on a keyring so a good way to keep together, but you can take one off without any difficulty.

Decent product but one of them is bent out of shape and is useless. I may never use that one though but when I do, I will have to hammer it back into shape.

Great little set for occasional use

Having finally done some reading around guitar set-up, I wish I had done so years ago! It's not as daunting or mysterious as it appears. You do need some measuring devices - such as this radius set but they are relatively inexpensive. These gauges finally helped me solve the mystery of the bridge set-up. Good quality product, with the full range to cover all makes. My order was processed very promptly and received ahead of time and I've no hesitation in recommending both the product and the supplier. First rate.
