Guitar Neck Notched Straight Edge Luthiers Tool for Gibson Fender and Most of Guitar Fretboard and Frets

A great tool for checking neck straightness. It worked on a compound radius guitar perfectly. Nice of the maker to add the finish instead of leaving it bare metal. It looks and feels like a quality product. Definitely worth the money and I imagine it will last a long time.

The description seems slightly English-impaired, I wasn't getting my hopes up that the product would be perfect. The first thing I did was check both sides of this straight edge against multiple machined straight surfaces. I also checked from each extended tooth to the the back of the straight edge using a digital caliper just to look for imperfections, it measured true to at least +/-1000th of an inch. I say at least because that is the precision of my caliper. I'm not one to white knight for every product I buy but true is true and this product is dead accurate. Some reviewers are using their particle board amplifiers and the top of their glass desk to check this product for true....come on man....you really shouldn't be making modifications to your guitar if you can't discern between a true machined straight edge and a composite box. You can't check a product whose only purpose it to provide a true straight edge against naturally imperfect surfaces. I was happy that the spacing of the teeth allowed me to use this on a Jackson, PRS, G&L Tele and a BC Rich. I'll check more when I get around to them but I don't foresee any issues. On the downside, this product is very thin, coming in at around 3/32 of an inch. While it does stand up on its own, it will not stay stationary while you turn your rod. Not a huge deal but I'm sure the price reflects the surface area. My biggest issue will be keeping it out of harms way in between uses. It has a drilled hole on one side so hanging it above the work bench would be a good idea. Super pleased with the product

Its a decent neck relief gauge especially for the price. It doesnt feel cheap or look cheap. Its straight and level; it works as you would expect. One or two of the little notches are a touch short of the others but it is so minimal that it doesnt impact accuracy. If you are looking to get down to an exact millimeter of relief - this is not the tool for you and at less than $20, it shouldnt be. Its also a little sharp on the edges, but not in a way that it will damage my guitar and not anything I will address. I used it against all my guitar necks and checked it against a guitar that I just got back from a luthier and its as accurate as I need it to be. If you tinker like I do, this is perfect. If guitar setups are a job for you, I would go with a more expensive name brand tool. They are bigger in size, likely accurate to a millimeter or more, and contain multiple scale/fret board accommodations.

It worked for my guitars.

That’s a great product. I don’t have devices to measure how straight this is but when I put that on a straight surface there’s no noticeable gap so I assume it’s straight enough visually. I actually use the not notched side of this straight edge to measure neck relief and it’s quite helpful and better than measuring with capo and string because the string is flexible and finding the right thickness with feeler gauges can be a bit tricky. But this helps you to accurately measure the exact gap since it does not stretch like a string when I push a feeler gauge.

Good quality and straight as can be .

Works perfectly on my Gibson, Epiphone, Fender, Squire, Guild, and Yamaha guitars. The spacing is correct for all. When laid on a thick flat glass, the notched and straight edges are even and work perfectly on my guitars. It is moderately thick so won't bend or flex. Not so thick it will stand on its own, but sufficient for the job. Happy with the price and performance.

This is a piece of plastic so it's not really flat and shows a bow on a flat surface (granite surface plate). I would assume that some could be more/less bowed since it is plastic and can be influence by the environment while curing. It is flat enough to put on a guitar neck that needs adjustment but it's definitely not precision. The product I received looked like it had been opened, used and returned. The spacing on the frets groves are a little subject but it did fit on a 22 and 24 fret neck.

Luckily my notched straight edge came in both quickly and true. A little smaller than I anticipated. Did the trick on my Fender Strat.

Muy buena calidad y muy util.

Prix élevé pour un qualité médiocre la règle était en outre voilée..

I bought this as a test of quality, to see if this brand would be decent quality... The answer is no. This item is useless. The notches are uneven and there is a recessed bow in the from the 4th notch onward. Absolutely useless. Would have ruined my guitar's neck if I didn't check it against a real straight edge first. It's a shame because it feels nice and solid. Shame the manufacturer can't cut straight...
