String Action Gauge Ruler, Guitar Height Gauge Set Up Tool for Electric Bass and Acoustic Guitar

It works well and doesn’t job. It is easy to use and seems to show accurate measurements. I would recommend.

Good quality steel measurements are easy with this must have tool for at home use!

The item works great. Lost a star only because the printing wasn't perfect. Still works great

This ruler is great for quick measurements to make sure your action is high or low enough. I've used it for guitars, basses, and mandolins.

I don't expect I'll be using this gauge very often but when you need it, YOU NEED IT! This is much cheaper than having to pay for a set up.

All is AOK!!

It’s got many different measurements for your guitar. I used it to set string height, works very well..

Because the item was cut/stamped out of a sheet of metal improperly after printing, all of the millimeter measurements on the long side (what you would use for measuring string height and pickup height) are off by a quarter of a millimeter (i.e., what shows as 1.5 mm on the card is actually only 1.25 mm). 0.25 of the measurement scale has been cut away for all of the heights shown. I'll just buy a better one rather than have to do mental conversions between what the card says and the actual measurement each time. Also, as other noted, the edges are sharp and slightly bent from the stamping process.
