I use this to check the relief of my guitar after I do a setup. I put a capo on the first fret and hold down the last fret then use the feeler to measure the gap at the 8th fret. I like my relief from 0.006 - 0.01" and this set has those measurements and a ton more.

Guitar shops sell this type of tool for $30. This set was a fraction of the price. The only downside is it comes heavily oiled so you'll need to wipe it down with a paper towel on first use.

I've played guitar for several years now, and only in the past few months have I begun seriously working on guitar setup/repairs as a luthier. The one glaring problem I had as a budding enthusiast was that my tools weren't up to snuff (what average workbench setup has gauges designed to measure in thousandths?) After cringing at prices from LuthierSupply, StewMac, and the like, I stumbled onto this feeler gauge in my Amazon recommendations (thank you once again for reading my mind...though it is getting a bit creepy...)

For under $5, it seemed like a safe bet to take a chance on, and I snapped one up immediately. Upon opening, the first thing I noticed was..oil. Be warned: The blades come packaged with some form of lubricant between them that I doubt most would want to spread on other surfaces (like the fretboard of your guitar for example). After wiping much of the excess off, I examined the actual tool:

The blades themselves are very well made, easy to read, and are perfect for measuring everything from variances in fret heights (those that are impossible to gauge by eye) to pickup and string height (in order to setup action and neck relief). For those measurements exceeding 0.025"/0.635mm it's a simple matter to add adjacent blades in combination up to a total of 0.328"/8.332mm. This is made possible due to the fact that the first blade on the wheel is actually the .025"/.635mm, allowing gauges to be added progressively from the smallest value up. Perhaps this is obvious, but I did not see it mentioned in the item description, and it does increase its overall usefulness.

Seems like a well-made product; covers a wide range of thicknesses. I got it for guitar setup (e.g. measuring neck relief) and it has done the trick.

It's a cheap set of feeler gauges, which come well-oiled because they'll start to rust the instant you wipe the oil off. That's just the nature of the beast with these things.

To their credit, they put the .025" feeler on top and followed with the .0015", .002", and so on. This greatly helps to keep the paper-thin gauges from getting mangled when folding the unit up after use.

I can't complain about this thickness gauge set. It is not flimsy or cheap, but rather a great value. The quality is shop quality, and goes down to .0015, which is something I use nearly everyday as a machinist. I am completely satisfied.

I really did need this tool to help me set the point gap on my old 1969 Chevy
pickup. True most motors these days have electronic ignition, and my mechanic told
me I should do that to this old truck motor. However, if you can still find ignition points
(I found them at Autozone) they will still get your motor running, head out on the highway,
and all that. This Great Neck tool was a great buy and a high quality tool. Even with the
shipping cost it was still a pretty good bargain. I will purchase more items from this
Amazon Merchant and will feel okay about it. The seller was very anxious to please
and shipped this tool very fast, which I do appreciate. Thanks again!
