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

Works great I needed one to check the necks on my guitars to see if the truss rod needs to be adjusted, good price a lot cheaper than a stew mac]⁰

Perfect for my use. Very well constructed.

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.

Very good straight edge. Fits my Les Paul frets. Very well built aluminum I believe. Would highly recommend.

Straight as an arrow and affordable!

Unless I'm missing something, this is a fine bit of guitar kit that works great. Very handy to have with necks that have adjustment at the heel (still a pain, but this helps immensely)

It's straight, and it fit on my MIM Player Strat. Helped me to figure out why my low E string kept buzzing badly... Got the neck straightened out, and it plays well now.

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.
