Guitar Tuner - NS Micro Guitar Sound Hole Tuner - For Acoustic Guitars, Ukuleles - Non Marring Sound Hole Clip - Quick & Accurate Tuning

Nice and discreet. It will make you look like as if you are tuning by ear. lol Quick and precise tuning. The only nitpick I can think of is, it's not so tightly clamped to your soundhole and you might accidentally flick it off while strumming hard.

The LED is broken or isn't working properly. I tried with 2 brand new batteries and still not working well. Can't read the numbers or name of the notes

I’ve put these D’Addario NS Micro Soundhole Tuners on four of my acoustics because they’re that good. They’re tiny, stay hidden inside the soundhole, and don’t mark the guitar. Most importantly, they’re accurate — I compared them to my Peterson strobe and the results were impressively close. They’re always ready when I pick up a guitar, easy to read, easy to use, and switching them on and off is effortless. I check tuning every time I play, and these make it instant. Battery life seems solid so far. A brilliant little tuner that just works.

It works great, feels like it was factory installed and is all but invisible. SO much better than having a bulky clip on tuner on the headstock, falling off, getting lost, left at home when you need it at a gig. This thing is great. If there was an improvement I would suggest that the screen be a bit bigger and a bit brighter. You have to get the viewing angle just right to see what you are doing. But I would recommend this product for sure.

Das Gerät ist sehr praktisch und kann permanent montiert bleiben. Besser als die Clips für den Gitarenhals.

È molto piccolo, questo fa' si che, una volta nella buca, rimanga ben nascosto all'interno. La clip metallica per ora sembra ben realizzata ma è troppo presto per dare opinioni, infatti, la clip d'attacco alla chitarra, per questo tipo di accordatore, risulta spesso il punto debole. Il display è piccolino ma dalla lettura chiara ed intuitiva. Insomma vale quello che costa, funzionale, pratico, fa quel che promette senza fronzoli inutili.

The D'Addario PW-CT-15 tuner is barely noticeable on my guitar, so I leave it installed for immediate use any time. It works great, because it's easy to read from the player's position and is more accurate than a headstock tuner. My guitar sounds better than ever when I use this tuner. I'm glad I wasn't scared away by the negative reviews posted by some users. Here is my take on the issues they raised: (1) Guitars come in all shapes and sizes. This will fit most, but not all. Before buying the tuner, make sure that the clip will fit on the wood around your sound hole. For example, it might be too snug if you have an extra layer of reinforcing wood around the underside of your sound hole or a thick pick guard very close to the hole. A flat area up to 6/16" from the edge of the hole and up to 2/16" thick should be fine. Some reviewers reported that the clip was too loose for them, but the current model has a metal spring that should hold the tuner in place on thinner tops. (2) Guitars also have different bracing patterns. Make sure yours has room for the tuner between the hole and the bracing. You need space for the shape of a triangle with the corners cut off about 1-3/8" wide (accross the hole) and about 3/4" deep. For example, in the Taylor line, it fits my Grand Auditorium guitar with X bracing, but it might not fit in a GS Mini or anything with V-Class bracing. [UPDATE: I got a new guitar and can confirm that it works fine on a Taylor GA with V-Class bracing if you put it in the 7:00 position instead of 6:00. You can still reach the power button and see it fine.] (3) Press the metal release tab to take the battery out without breaking the plastic tabs that also hold it in place. The manufacturer's video shows this clearly. (4) Install and remove the tuner carefully to avoid breaking the clip. This is easy to do, as shown in the manufacturer's video. For me, this is a fabulous upgrade at a very reasonable price.
