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

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.

Works great and is more accurate than a headstock tuners

Extremely low profile tuner is an absolute must have. Perfectly located in line of sight and visible through strings. Its always there and isn't the eye sore that clip ons are. I have one on my Taylor and its absolutely amazing. Doesn't affect the tone of the guitar at all and it is secure so I'm not worried that it will fall off (or in). Bright enough to be seen in any light, super accurate and easy to use. Just turn it on and let it do it's thing and for a great price. Get yours before they get smart and start charging more for these. Seriously, anyone with an acoustic guitar with a sound hole needs one of these. Period!

I used the predecessor to this tuner on one of my classical guitars for a couple of years, and found it quite good. Easy to install, easy to use, accurate, unobtrusive, and with a good battery life. Unfortunately, after about 2 years the display began to fade, and replacing the battery didn't revive it. Still, I liked it enough to invest in this new model for a couple of my instruments. This new model is as accurate and easy to use as the older model. The original red/green display has been replaced with a full color display -- hopefully this new display will last longer than the old one did. the design is still simple, but installation has become a bit problematic. The older model remained where I had clamped it for 2 years without issue. For some reason the clip on the new design doesn't seem to want to hold the tuner in the guitar as well. About every 3rd time I turn it on or off, it comes loose and falls inside the guitar. I solved this problem by attaching some double-stick pads to the top of the tuner, that contact the inside of the top near the sound hole. I think if d'Addario put a couple of rubber pads on the surface of the tuner itself, in these same locations, the problem might be fixed, out-of-the-box. Regardless, it's a good tuner, at least worth 4-stars. If they improve the mounting clamp, it will be worth 5-stars.

Inconspicuous and awesome. My acoustic guitar doesn’t include electronics so I needed a separate tuner. This sits inside the sound hole and can stay there without looking clumsy or getting knocked off. It has a full color readout and works great! I’ve even bought them for friends and family and we all agree that they are great!

If you haven't used one of these before, it's a great little device for tuning your guitar or other stringed instrument. This model fits inside the sound hole of your guitar and is easy to see. The built-in tuner on my guitars are in a place where it's not always the easiest to see. This has solved the problem.

There are a lot of very good digital guitar tuners now, but I always thought most of them made a fine looking guitar really ugly when the tuners were clamped on the peghead. This one slips into the sound hole, and is visible from just underneath the sound hole's lip. Its ver easy to see when playing the guitar, and so unobtrusive an onlooker wouldn't even notice it at all. The little control buttons have to be pushed with the thumb, but they're easy to find and easy to work. The device sets snugly on some small silicone pads that protect the finish, and requires a practice try to learn how to put it on and take it off, but once you learn it, it's easy. An it's very secure when installed. Another nice touch is the battery can be removed and replaced easily while the tuner is installed. The manufacturer recommends removing it when a guitar will be stored for a long time, but can stay put under normal use. I really like it. The tuning is fast and accurate with no jitters. The display is always shaded by the placement, so it's always brightly seen, and it keeps my old guitar looking as elegant and handsome as ever. I'll probably buy a couple more of them for some other guitars. This is an item that is designed solely for acoustic guitars or other acoustic instruments with a round sound hole. They won't work on a solid body or a guitar with F-holes. But it should fit any guitar that has one; it's quite small.

Could not get it to fit in my Taylor 50th Anniversary series. I ended up putting it in my Ovation guitar. In my Taylor, I accidently dropped it in to the soundhole and spent 5 minutes retrieving it.

ギターのホール部分にセットしてチューニングしますが、画面の液晶の文字が逆さまに見えて使いずらい。説明書も無いので調整できない。でも、正確にチューニングできる。見た目もカッコイイので２つ目です。

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.
