This compact, intuitive, and reliable tuner boasts an impressive accuracy within 0.02 cents, making it an essential addition to your music gear.

Chromatic and Strobe Tuner

Highly recommended, I got it second-hand and it is one of the purchases I have made the most use of, the tuner is the most important pedal of all.

It can tune in different tunings other than 440 Hz and power more pedals thanks to its second 9v input, which can be used as a daisy chain.

True bypass, it performs its function perfectly, mutes the rest of the signal to tune.

Preferred Settings + Usage:

yo no uso mucho la función de afinar todas las cuerdas a la vez, pero sin duda es una función única; la afinación cromática no da ningún problema, la estroboscópica es un poco más compleja de entender pero es muy intuitiva

Versatile, very easy to use, solid and consistent.

The strum feature is really cool for those of us who can’t tune by ear. It displays how all your strings are tuned relative to one another simultaneously. If you’re flat or sharp somewhere, the strum feature finds it for you immediately without having to go one by one.

It has more features than I use, but they’re easy to access should I ever need to.

My preferred tuner over the Boss TU-3

I know there are other accurate alternatives out there (eg Peterson) but between the big two — Boss TU-3 and Polytune 3 — I prefer the latter.

For one, the display is just easier to read, particularly on a darkened stage. I don’t use the strobe tuning feature but even that is more visible than the Boss. Where it’s really at for me are the big letters for the string/note you’re tuning to. And it auto detects, so for someone like me that uses a capo a lot, you don’t need to pick a different mode (although you can program tuning up/down or alternate tunings).

Oh and it has a good buffer to start your board with.

Preferred Settings + Usage:

I use the single string tuning. I’ve never tested/compared to the multi string tuner, I just find it easier and quicker as a personal preference.

Even if you're a beginner, at least you'll be in tune.

Polyphonic tuning (multiple strings at once) is a nice feature for a rough check. One string at a time gives more accuracy with the strobe effect letting you know which way to adjust. Big display is easy to see.

Great for an always-on tuner!

This is the first thing on my board, not only as a buffer, but I have it set to always-on, so I don't have to stomp it to tune up, and I can always hear my playing (I am not performing live or anything, but if I were, I'd reverse that setting). On the flip side, I can hit the switch if I want to mute my signal at any point, and still have access to the tuner functionality. I like that it can also daisy chain power to another pedal. The only negative, really, is the namesake poly tuning mode is not nearly as useful as I once thought it might be. It could be improved greatly if the screen was used better in that mode, but the reality is, maybe it's just not that accurate to do so. Oh well, I can only turn one tuning peg at a time, anyhow.

Quick and Accurate

The Polyphonic tuning is perfect for quick tuning in-between songs or recordings, works quickly and is accurate with a choice of 10 cents up or down from standard 440Hz, with support for drop D tuning. nice and bright display for darker environments.

Everything you need, and a little bit more

Tuners are very easy to get right, but it's always nice when one goes above and beyond for those who crave efficiency. Not only is the PolyTune 3 an exceptional tuner with great accuracy, a good range of tunings and a nice, bright screen that's impossible to miss, but the buffer is a very welcome addition, and the ability to daisy chain & power other pedals through it is a lifesaver for my busy board with far too many wires.

Like I say, there's normally not much in it with tuners (for most players at least), but if your needs are straightforward and you like to get the most utility out of your limited board space, it's hard to beat this one

Good value for money

Good value for money. You can get a very accurate tuning with the strobe feature. It's easy to learn how to use and you will hear how much better your guitar is tuned right away.
