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

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.

Very nice 👍

I'm a novice guitar player and wanted a simple tuner that would also allow me to tune to alternative tunings - my headstock tuner doesn't do this. This little gizmo does exactly what I want and was easy to fit on my guitar and works perfectly. Why only 4 stars then? Well, that's because there were no instructions included and not even a link to a website! OK, it's a tuner - doesn't need instructions. But what about the calibration button? The engineer in me thought I'd have to calibrate this against a reference because with measuring equipment that's what you do! A quick Google informed me that there is a global standard for the frequency of the note "A" and that is what the tuner is set at. Why wasn't that info included in the blurb somewhere? I then discovered that in some cases, some musical instruments may be tuned a few Hz higher or lower and this calibration button allows you to get in tune with them. Like I said in the first line - I'm a novice - and now I've learned something.

Seems a lot of money for its size, but it works as described, hard for anyone else to see, so unobtrusive. Just clips on to edge of sound hole, so only for acoustic guitars. Easy to use, plus you can offset the A 440 Hz going from 410 to 480 Hz. Clear display.

I purchased this item with my own money and have not been provided with any incentives to provide this review.This is my favourite tuner, its sleek, accurate and easy to use. Hardest part is placing it inside the sound hole of the guitar.Good value for money, battery lasts well, is easy to see and use and allows you to look at the specific string and see where adjustments are required unlinke many other tuners that are either clipped onto headstocks or connected via amps etc.Makes a great gift for any acoustic guitar player or a great addition to your kit to replace an old tuner.

A neat little tuner that clips on OK (Guild D-50). It has survived it's first pub gig and worked as advertised - easy to see the display in low light too.I think the key to this device is to fit it where there is a single thickness of wood. On my guitar there was only one point where there wasn't soundhole reinforcement strips underneath and the pickguard was not too close to the soundhole - you need at least 7.5mm from the edge of the soundhole to the pickguard (if fitted) to fit this - I hope this helps.Update: Still working fine 11 months and 70 gigs later and on original battery. Has only once fallen off and ended up rattling around inside the guitar like a 2 ton plectrum. It's fitted to a sound board that is 3mm thick - any thicker I think puts too much strain on the clip which is probably why some people have had them break (minimal instructions with product don't give any guidance on this, though I note that their website now says 3.81mm thickness)Update 2: Three years of use and still going strong and battery life is good - the only other issue I have found is if you are playing outside on a sunny day as during Covid, the display is very difficult to see. Hope this helps.

Nice and compact and hidden, all qualities I like. Not too strong hold so if not placed against something might fall inside when the start button is pressed. I place it against one of the bars inside the guitar and it doesn’t move or falls in.Apart from that, seems a good buy for someone who wants it hidden and not too obvious and also always there.Tuning seems accurate and on point. I like that it is easy to read and the display is bright enough to be seen even on daylight.So far pleased with it.

This is an astonishing, simple and discreet bit of kit. It works on all the strings of a 12 string guitar which are known for being difficult to tune. You can also use it for open tuning. For the price you cannot go wrong. There is a warning on the box that the clip that holds the tuner in place can react and leave a mark on certain finishes. I've got it fitted on my 12 string guitar tuned down a semi tone. It's very accurate to my ear. I can't comment battery life as I have only just recently fitted it. In general most reviews are very positive about this tuner and I think it's worth the money.

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.

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.

Good value! I’ve bought three of them now! If you have an acoustic that doesn’t have a built in tuner; you need to buy one of these for each of them! The accuracy is as precise as you could want. It is very low profile so it will not detract from the guitar. Only bone to pick was lack of any rudimentary instructions. Not that it is complicated. The battery did not snap shut after removing plastic from the negative side of battery. I wrapped a small piece of electrical tape around batter holder. I would recommend this tuner. Perhaps with instructions more care and a YouTube video you could avoid my problem

Petit mais précis, quasi indecelable, il reste à demeure sur ma guitare. Ainsi toujours à portée de main. Bien que débutante, je pense avoir fait le bon choix !

Discret, fonctionnel. Peut rester accroché à la rosace aucune gêne. Bon produit
