TC ElectronicPOLYTUNE CLIP Clip-On Tuner with Polyphonic, Strobe and Chromatic Modes and 108 LED Matrix Display for Ultimate Tuning Performance

I've use the Polytune on my steel string Levin acoustic guitar. It has a very bright display and is quick to use as it "catches" the note and holds it steadily as you tune, and if you strum the open strings it indicates which strings need attention.The display adjusts to remain upright whether it's clipped to the the back or the front of the of the tuning head - I find it more convenient at the back.I used to use the much cheaper Fishman FT2 tuner which is just as accurate, but the display is not too bright and it's more fussy to tune the note in. The Polytune black version used to cost about $90, so when the price dropped I bought it. It's a well made quality item that's a pleasure to use.I've been using it now most days for 4 months and haven't needed to change the battery. Occasionally it fails to catch the note and displays the previously tuned string, and sometimes it shows the open strum mode when I'm trying to tune a single string. Damping all the strings and trying again cures this. But otherwise it's quick to use, very accurate, and appears to be one of the best clip-on tuners.There seems to be 34 divisions/dots for each whole tone - so from one dot to the next is about 6 cents. So I guess when the tuned in, and all of the dots are green, it's probably accurate to plus or minus 2 cents, which is pretty accurate. There is a strobe mode which is said to be more accurate but I find it too fussy to use.The only improvement I'd suggest is a custom setting to adjust the intonation of a single string as the B string needs to be sometimes slightly flattened to sound right.My comments apply only to home use so I don't know how well it would perform in noisy environments.

I've used and still own several of what they call a "Super Tight" tuner and they are just fine and accurate enough but this TC product is a pleasure to use as well as a bit more noticeably accurate...I have more accurate and expensive strobe tuners but with my slight intonation errors as well as minute fret wearing we can only tune to our best ability, then I do my final precision tuning with my ears accepting what I feel sounds best...I've long recognized my tuners only get me in the close neighborhood of what sounds perfect, my ears do the rest... My guitars are also routinely adjusted for intonation and fret leveling every year or so...

Great tuner! High quality and sturdy build!

I love this little thing! I never use the polytune feature, where you can strum once and know which string to focus on tuning. I always check each string individually. And for this purpose, this tuner is awesome! Worth spending a bit extra. Nice, big, easy-to-read display. Doesn't bounce around a lot. It's not "noisy." Get one! :)

This is simply the best clip-on tuner I have ever used! I have used Korg AW-1 clip-on tuner for the longest time but its display was always hard to read. Last year, I "upgraded" to D'Addario PW-CT-12 clip on tuner. While I loved the size and that I can just leave it on, it has been challenging to get that final cent adjustment due to the display. I always end up tuning by ear after that. It also struggles to pick up dropped tuning with my acoustic guitar (low string down to B-flat). Now, come TC Electronic Polytune! Wow, I love how I can tune in the last fractions of cents so quickly! I have never been so happy with the first round 1-minute tuning result. Comes out perfect every time. One caveat is the sturdy but tight and small clip. It barely fits my guitar headstocks and I would not leave it on.Tuner performance easily outweighs the con. This tuner is highly recommended for discerning players looking for precision.Unfortunately, I'm taking 1 star off for receiving an open used, missing box top, sold as new, and $20 over MSRP.... Not the product fault...

Easy to use and accurate tuner

Very good and nice tuner...

The Polytune readout is far more responsive, easy to read, and accurate than any other tuner I've ever used. I can immediately see whether I've hit the mark, and — my favorite feature — if you strum all the strings it will show you their relation to one another and reveal any that may still not be quite on point. When I need to retune on stage, I no longer feel anxious about keeping the audience waiting — Polytune Clip makes it go quickly. Worth the price, for sure.
