D'Addario PW-CT-15 NS Micro Soundhole Tuner

While tuning using this tuner in tandem with the inbuilt tuner in logic pro x connected via Scarlett audio interface, I noticed that some strings were flatter than the desired frequency when I used this tuner, but got a more accurate pitch, both on the DAW and my ears when I retuned the guitar using the onboard tuner on my logic pro x.

Great while it works. Stopped working in 6 months. This is probably the most convenient and easy to use tuner that I have ever used. (And I have 6 guitars and about 10 different tuners in different kit bags.) It's form factor is so great that it is there when you need it, while not coming in the way when you dont. In fact it is so out of the way that you dont realise its there until you need it. Cant complain about accuracy. It's great. But within 6 months it suddenly stopped working. Then i ordered another unit. Same issue out of the box. Here's what happens to it. It blinks and blinks on turning on and doesn't start. LED display keeps blinking. As of now, I have tried 3 of the same model units and it all has the same issue. Do not buy this. Instead get the clip on version from the same company. I have one since a year and it works all the same still.

I use a martin guitar & it doesnt have a tuner. Usually expensive guitars like Martin/taylor don't have one. I was about to buy a clip tuner for Rs 250, but thought to keep it classy & nano. I spent 6 times more ie Rs 1800 & what did i get? *The thick strings D,A & E when plucked, the tuner doesn't respond. It takes a lot of time to recognize the voice of the string & is not even Active for Good stage shows. Waste product. I even replaced it (As there was no return option,i would lobe to return it) SORRY D'ADaRio, The product is over priced with no utility.

Display not clear enough or maybe I got a bad unit

Got spoilt after 2 months of use.

this has an open battery slot which means any moisture or impact or anything can cause trouble. i have micro daddario tuner and it has worked great for me but this one has been disappointing i had exchanged 2 pieces both were faulty but good that amazon did refund my amount

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.

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

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.
