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.

Straight as an arrow and affordable!

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

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.

Good tool. Helps a lot

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.
