Stringed Instrument Action Ruler Gauge Luthier Measuring Tool for Electric Acoustic Guitar Bass Ukulele Mandolin Banjo SAR-10

Pretty decent item, especially for the price. Probably wouldn’t mic out as quite as accurate as the high-end versions, but will get it done for occasional DIY action maintenance.

Used it for me I adjestments. Stops guesswork.It's long enough to find loose frets by feeling for a high fret.

Purchased this to check the action on my vintage Guild guitar. It works great. I was able to check and adjust the action after the guitar sat idle for more than 20 years. If you plan to maintain your stringed instrument yourself, this is an essential tool at a good price.

The gauge arrived in a timely manner, but it is a bit scratched up which is disappointing as it is a xmas present for someone. That said, I did not try to return it as I don't effect its function

Don’t forget to remove the protective plastic on both sides of the ruler.

Sturdy metal construction. I did not expect the multiple scales - now I'll have to find other uses for the product.

This baroque ruler was really accurate and handy in helping set a low action for my les Paul

Great product price is a bit high though
