D'Addario String Height Gauge

A very useful tool from a top brand manufacturer.

I bought this based on the great reviews and glad I did. It’s well worth the extra couple of euro. Highly recommend !

My go to for setting action on all my guitars

Trusted brand, robust and useful, however could be easier to read if was matt black with white measurements especially for those with older eyes, so only 4 stars.

Very handy tool that that gives reassurance that you have set up your guitar to spec.

Had a couple of these from generic overseas brands that were next to useless - with wonky edges and/or wonky printing meaning they didn’t provide the precision measurements needed for guitar setup. This one from D’Addario looks very similar, and for all I know was made in the same factory, but has obviously been subject to the quality control you’d expect from a trusted company like them. Slightly pricier than some other examples (and a little harder to read than some rival designs) but it does the job and you can be assured it’s providing you with accurate measurements. Worth paying extra for that rather than taking your chances to save a few pennies, I reckon. Recommended.

This is a little more expensive that other cheap versions, but you're paying for the quality. Printing is very crisp and clear and feels good to use in the hand.

Good quality stainless steel and the markings are clear
