TC Electronic POLYTUNE 3 Ultra-Compact Polyphonic Tuner with Multiple Tuning Modes and Built-In BONAFIDE BUFFER

I was on the fence about whether to choose this unit or the comparable Boss TU-3 unit. They're both the same price, and both get good reviews. I finally decided to go with this unit because it's a newer design and offered both conventional and "strobe" style tuning. The latter appealed to me because I have been using a Peterson Strobo-Clip tuner for some years, and really like the strobe tuning method. I decided I wanted a stomp-box tuner so that I could mute the sound and do quick tune-ups more conveniently than the clip-on tuner permits. I play electric bass. I found that the conventional tuning mode on this Polytune 3 pedal was just fine for my needs, and I have not yet even tried the strobe version. It also revealed that I need to touch up the intonation on my jazz bass -- playing various notes up and down the fretboard showed some deviation from the correct tuning. All the more reason not to need the micro-precise tuning of the "strobe" style display. When I say "conventional" tuning display, I mean a display that shows a needle that is positioned to the left of center if the tuning is flat, or to the riht of center if the tuning is sharp, and dead center when the tuning is correct. Some tuners have arrowheads on either side of center that light up when you are not quite at the correct tune. With this unit, the needle itself changes color, displaying as red when the note is sharp or flat, and green when it is correct. It is very quick to go through the four strings of my bass and tweak it for the needle to be green. This is a chromatic tuner, meaning it listens for the incoming note and displays what it thinks the note is. That works fine for me. It is only necessary to know that the standard 4-string bass tuning is E A D G. There are handheld (not stompbox) tuners, like the Boss TU-12, that have fixed presets for tuning a guitar or bass, but that is not generally available on a stompbox. The Polytune 3 has a "soft" pushbutton that puts it in and out of tuning mode. By "soft" I mean that there is no mechanical ka-chunk as the sawtich is operated. When the unit is tuning, the output is muted. When tuning is finished (by pressing the switch a second time), the output is connected again. There are three modes available, which are selected by internal DIP switches. The first mode provides "true bypass" switching when the tuner is turned on and off, which means that when it is not tuning, there is a direct connection from the input jack to the output jack. The second mode provides "buffered bypass," which means that the incoming signal passes through a "buffer" amplifier when not tuning. (This can be advantageous in a number of situation, especially if long cables are being used.) In both of these first two modes, the tuning display lights up only when the tuner is active and the output is muted. In other words, you can immediately tell whether you are muted or not by looking to see whteher the tuning display is lit up. The third mode is also buffered, but the tuning display remains active all the time. Thus, in theory, you can watch your tuning as you play. I have only used this unit in the second mode (buffered bypass, display on only when tuning) because that best suits my needs. There are many features which I may never use. For example, while the factory setting is A=440 Hz, it is possible to adjust this reference. Also, the unit is advertised as allowing the user to play all the notes on the instrument at once, whereupon it claims to be able to sort out which of the notes are off. I don't see any particular benefit to this for the bass, and I have read that users do not believe the tuning accuracy is quite as good in this "polyphonic" mode. Frankly, it doesn't take very long to tune 4 strings individually, and that's what I do. Since my bass keeps tune pretty well, it only requires minor tweaking to deal with room temperature change, etc. This takes no more than a minute at most. All in all, I'm very happy with my choice of the Polytune 3. It's very easy to use, has quite a readable display, and makes keeping in tune during a show very simple. I suspect the competitive units out there (like the Boss TU-3 or the Korg Pitchblack) are also fine, which may make the choice more difficult in this category. All I can say is that I think people would be happy with this well-made unit, so hopefully that will help with the decision.

The chromatic tuning is great and tracks very fast. I love that! The strobe mode is awesome as well and I like using it. The display is nice and bright and I love that too. The note names can be a little hard to read but it’s decent. It can be true bypass or buffered, so that’s a win/win. It has a 9 volt non isolated output to daisy chain, and that can come in handy if your other pedals don’t mind non isolated power. So for all of that, 5 stars, but: The Polytune feature that lets you see all strings at once is not accurate. It is useful though for a quick glance. Your E string will almost always show that it’s flat when you are polytuning. The drop tune and capo modes only work when using the Polytune feature, so they can useful for polytuning in non standard, but your actual tuning will be done chromatically. Overall, a real winner, especially for the cost.

I've been playing guitar for about 17 years and this is the BEST and most ACCURATE tuner I've ever used, and I've had more than a few, various brands and sizes. I would chose this tuner over any other brand. VERY EASY to use. It's EXTREMELY versatile- you can choose between true bypass or buffered (I use buffered), chromatic, strobe, or polyphonic tuning modes (I always use strobe), 9v battery or power supply, toggle between multiple tunings and frequencies and more. I use this tuner on my pedalboard and also on my workbench- it tracks notes almost instantly and the strobe mode is accurate enough for setting intonation. It has a soft touch switch, so there's no noise when turning it on or off. The display is perfect- bright, easy to read, not crowded, and the colors make it easy to see what's going on. It even has a 9v pass through that can power another pedal. Incredible. Cheaper than buying a tuner and buffer separately. I'd recommend this tuner to anyone. This is the last tuner you'd ever need. I might even buy another, just for the convenience of not having to take it off my pedalboard when I want to use it on my workbench- it's that good. I'm even planning on getting a Polytune Clip for my acoustic guitars. Plus, it comes with easy to read instructions and a free sticker...which is always a nice bonus in my book.

PROS: Best tuner on the market. The addition of the bona-fide buffer is an absolute win-win as it gets both the buffer and tuner first in the loop. Yes, many pedals buffer the input now, but not all buffers are created equal. Make no mistake this is a high quality buffer that will eliminate tone suck almost 100%. I like how you can configure the internal switches for always-on tuning and true-bypass if your situation dictates that need. Pedal remembers your tuning/instrument preference which is great, screen is very readable in different conditions. Strobe tuning is a great feature for that .1 cent accuracy for studio work or bridge intonation adjustments. CONS: It can't all be perfect right? I really wish you could disable the poly-tune feature. Ironically this is the least useful part of the polytune IMO. Because I'm primarily a bass player I just have no interest in it. Does is work? Sure, best as I think it can. For me I want to tune 1 string at a time accurately as possible. Although the tuner switches from polytune mode quickly I have found in loud environments it can take a split second. In those instances It seems to hear multiple notes from the resonance of the instrument and take a moment to switch to single string tuning.. I feel many people will have no interest in this feature and really wish it could be turned off, it is a minor issue and I still recommend this tuner over anything else on the market in this form factor. The strobe tuning could be a litter clearer with a more dense LED array. It totally works, but at times you will need to concentrate on it to comprehend the readings. I initially intended to use this in strobe tuning at all times, but found its just a little cumbersome for live performing. The good news is the chromatic tuner mode offers .5 cent accuracy, which is twice as good as the main competition. I find this to be completely acceptable for live performing. The 1 cent accuracy of the main competition is fine is most instances, but as a bass player I find 1 cent off from an electric piano in the lower register is audible. Lastly the tuner seems to be on the heavy side of battery usage. It's certainly not the worst pedal I have used in this regard, but with an integrated buffer and a ton of LED's I guess its to be expected; Especially if you enable the always-on tuning. As a bass player I often find with just a tuner and a emulator/DI box its just not worth plugging in to AC power.

Glad I finally made the purchase. I Like this tuner. Display is big and bright for my terrible eyes. Is accurate (in my opinion) and simple to use. No more finding my clip-on tuner and tuning the guitar, just click the pedal button. One thing to say is my buddy tried to use the tuner and he has a hot pick-up. THE TUNER DID NOT LIKE THE HOT PICK-UP. Was going bonkers from note to strum mode and would not stay on one note.

I think this tuner is pretty good. The display is large and bright, and the accuracy seems to be very good -- especially in strobe mode. I like that it's buffered, which helps keep the signal strong throughout the pedalboard. Some things I don't like about it are: 1) You cannot turn the display off in un-muted mode. The only way to use it un-muted is to have the display, which is bright and can be distracting, always on. This is admittedly only a small annoyance to me, as I like to hear the guitar through the amp when I'm tuning at home. I don't want to slavishly rely on the device rather than my ears, but I really don't want that miniature circus of a display bouncing along with every note I play when I'm not tuning. 2) There's a pretty big discrepancy between the 6-string display and the single-string display: i.e., it may show all strings as being in tune when strumming them all together, but when you pick each string individually, some may display as sharp or flat. I guess this is acceptable, since the 6-string display is still useful as a quick check, and I'd expect to tune individual strings when I need the best accuracy. And the individual string accuracy seems to be very good. 3) Those with a visual astigmatism, blue-green partial color blindness, or just plain blurry old-age, medium-range vision (like mine) may find the red/green vertical indicator a little hard to interpret -- especially if there's need to tune quickly. The needle tends to blur, and it takes me a moment to focus and determine where the needle is (green) and where the deviation (red) is going. They tend to run together. I'm using it in Strobe mode, which helps, but even that, in combination with the needle, is tricky for me to grasp quickly. This was never a problem with my Boss TU model tuners (which I would probably buy over this if I had to do it over again), or my Peterson iPhone app, so I know there are displays that are easier for me to read.

Very Pro. Excellent tuna without the smell and need for a can opener in your guitar case. I keep bread and cans of tuna in my case for stage snacks between songs. I never tune my guitar because it was in tune when I bought it. I just put this tuner in my pedal board so other guitarists think I know what I’m doing.

I’ve used some other cheaper tuners that required a few seconds to pick up each note and they can be frustrating. This picks up the note almost immediately. I find both modes very helpful. When I have time to tune each string individually, I do so; but having the option to quickly strum all of them at one time and get a representation of if they are tuned or not is fantastically helpful. I found that the tuner was built very solidly and didn’t feel like it would break easily. I bought this model because I wanted to be able to use it without a separate power supply. I’ve owned this for about a month, and use it daily, and the 9v battery is still strong. Having the option to use a power source as well is also nice. This is my favorite tuner I’ve ever owned and I don’t know if I will ever be able to use anything else again that doesn’t have all the features this one does.

The way it shows the results is so fast and very responsive and accurate. The buffer in it is very useful.

Más que excelente, justo lo que necesitaba y con más funciones de las que esperaba, el afinador es bastante preciso y puedes checar la afinación de todas las cuerdas a la vez, la construcción del aparato es bastante rígida y el pedal es bastante sensible permite activarlo y desactivarlo sin mucho esfuerzo, por el precio no esperaba menos, se puede integrar a un conjunto de efectos sin problema, la pantalla tiene el brillo y detalle suficiente para leer los cambios mientras afinas. Tuve problemas para hacerlo funcionar en un principio pero era porque no había conectado el instrumento a la entrada del sintonizador, es fácil confundirlo con una falla, no vi indicando ese detalle en el manual, te ahorraría bastante tiempo si el fabricante lo indicara en algún lado, funciona tanto con una batería de 9 volts, como con un adaptador de corriente de 9 volts y que entregue más de 100 milliamperes, recomendable al 100%
