Good trainer for beignners. Exactly as described. If you gonna to train your skill or memory, this device is good choice I think. It's ligth weight and rather small. Portable to carry in a bag. No sound but good for training everywhere without distrubing others.

"I’m was unable to add or delete cords. seems to be stuck in a c, ami, dmi, g progression. asked what am I missing?" Nothing helped worked so return for a retry>

Haven't tried it yet just unpacked it. Look a bit plastic like hope it will do what I need it to do (help me practice. Cheap and verry confusing to use.

The person in the product photo clearly has no idea how this product is used. It works great to measure the height of your strings above your frets though. I took away a star because mine has some unevenly spaced markings.

This string action gauge is every bit as good as Stew-Mac, as far as I am concerned, and a LOT less expensive.That said, BEWARE SHIPPING TIMES. These ship from China and it took about 2 weeks for me to receive mine in Georgia, USA.

So this product was not what I was expecting, it is cheaply made after all. Even though is was helpful in rudimentary hand placement and memory pertaining to the distance of the strings, it really didn't help with anything else. It was akin to loosened ukulele in strings and sound

very sharp edges. I was afraid of scratching my guitar, but it seems sturdy. I used it as a guideline but only loosely because I like to use a capo on some of the higher frets and needed the action a little higher than the tool suggested.

I'm just learning to do my own basic setups for guitars, and this cool piece of metal is a gift from the heavens to me. Having this ruler, has made me look like I know what I'm doing, when setting up my own guitars, or one of my friend's guitars.It's a must have for anyone that is a guitar tech, or an amateur, at home, doing their own work.

Let's me use while without having to use whole guitar and disrupting others for learning were to put fingers to leard cords. Love this item would tell others to get

This item did not come with direction on how to use it and limited information on how to set it up. It's a total POS and a pain in the ass as well.

I ordered this as a stocking stuffer for my boyfriend since he purchased a used guitar and the former owner messed up the action on it. He loved that there were different measurements on it and he was able to hold it different ways.

A good all in one measuring tool for setting up your guitars. I am not a professional luthier, so I can't say what they use. But it's great for setting up and adjusting my guitars at home. It also looks like you know what you're doing if you let your friends see you measuring the guitar with a cool tool.

I would imagine most people looking to buy this are familiar with the industry standard brand when it comes to luthier tools.the one that rhymes with "blue-pack", and while I absolutely love their stuff, some of it is wayyy overpriced and their string action gauge is probably the best example ($18.95). This gauge has every single gauge and ruler as theirs which makes this a no brainer if you're in need of one.
