Daddario PW-CT-15 Micro Soundhole Tuner

I had read mixed reviews previously about this tuner but having bought and used it, I feel it's a quality little tuner. So much so, I've bought another 2 for other acoustic guitars. It's discrete which is nice - it fits snuggly into the sound hole. It's very easy to use.
I was somewhat concerned about the open nature of the battery but it's a tight fit so no worries about the batter falling into the guitar.....or the tuner for that matter. All in, a great little tuner.
Display is nice and bright also which is great - perfect during the day or night.

I have one of these in each acoustic guitar that I own,, There incredibly small and neat looking when installed, provide very good tuning and the battery seems to last a very long time. good tuner for the price.

You can literally stick this tuner in your acoustic sound hole and leave it there till you either need to clean it or change battery. It's also small enough so it doesn't affect your playing while strumming, picking or playing fingerstyle. It's very precise and you can tune your guitar quickly with it. I think it's a great little gadget and it's definitely a need to have, especially if you hate having so much stuff laying around i.e picks, capo, tuner etc.

I am now using this tuner on my ukulele and classical guitar. It fits perfect on both and is accurate enough. Easy to get to the battery for replacements and I would highly recommend this.

I love the fact that you can leave it on your guitar and its not noticeable.
It is accurate and you get immediate response.

It feels like the battery is going to fall, and it actually happens when it is not clipped to the guitar, but I haven't had any issue once it is clipped.

It is amazing! Accurate and faster than the PW-CT-12 Micro Headstock Tuner. It works like a charm. Positioning at the soundhole is even better and much easier while performing to use.

Great little tuner,fits in sound hole, easy see and operate, very discrete, doesn't interfere with playing or strumming. Only thing if pickgard is right up to soundhole, tuner might not fit. Otherwise highly recommended

This is unbelievably handy if you're trying to tune a guitar or ukulele in a crowded room. The display is nice and clear, buttons easy to reach and use and looks a lot better than having a screen dangling off the headstock of your guitar.

Bought this to replace my Daddario head stock tuner as I wanted something that wasn't very visible.

This tuner is ideal, very discreet, very responsive and easy to read with the bright red & green LED display.

Would highly recommend to anyone.

I absolutely love this little tuner! No more clipping my tuner on and off the headstock! It fits inside the soundhole very discreetly and is very responsive and accurate when tuning. I plan to purchase more of these and leave them inside my acoustic guitars. However, in my opinion they are a little bit overpriced for such a small simple tuner, other than that, great little things!
