Best Guitar Tuners – 9 Tuners Best For The Job!

It should be common sense that before buying any of the fancy effect pedals, a person should probably invest some of your money in a best guitar tuner that you can fit into your budget. A good guitar tuner enables you to avoid being frustrated as a beginner with your guitar not sounding like it should, and as someone who’s well practiced it allows you to save precious time and make your everyday life easier as a guitar player.

We’ve learned a great deal about various guitar equipment while working on our Gear Page, so we decided to try and come out with best of the best in terms of what’s being used by the well known guitarists, as well as what’s currently popular among people who play a guitar as a hobby.

So without further ado, here’s GroundGuitar’s straight-to-the-point list of best guitar tuners. For your convenience we’ve added quick links to each of the tuners, and separated them in three groups – reasoning behind each is explained at the start of each section.

Best Clip-on Guitar Tuners

Clip-On tuners are usually to be used with acoustic guitars, but they can be used on electrics without any significant issues. They measure a note using a high-sensitivity piezo sensor which measures the frequency in which the whole guitar vibrates when you pick a string.

This makes them ideal for loud environments as they do not require complete silence in order to work. To tune your guitar you should place the tuner on the guitar’s headstock using the clip-on mechanism, and monitor the note on the display.

Snark SN-5 Clip-On Chromatic Tuner

For $8 it’s really hard to find something worth complaining about the Snark SN-5. Yeah, it’s all cheap plastic, but it’s not like we expected aluminium casing at this price point anyways. What’s important is that the tuner does it’s job pretty well, and most of the people are probably gonna be amazed by it anyways given that they don’t have experience with some of the premium models (this happens more often than you think when it comes to guitar gear).

The tuner uses both the high sensitivity piezo sensor and the microphone for tuning. The display is sufficiently bright and clear (although not so much in daylight), and it’s highly adjustable (can rotate 360 degrees). It even has a battery saving featuring which dims the light after ten seconds, and completely shuts down the tuner after two minutes of idleness. Some of the SN models even have a built-in metronome.

Summary: Snark is certainty one of the least expensive tuners out there still offering a satisfying performance. It is perfectly suited for people who don’t want to be constantly worried about loosing or damaging it. If you happen to swing your guitar around a lot, or you’re one of the people who often take their guitars outside and risk the chance of loosing it; with Snark it’s no big deal. For couple of bucks you can get a brand new one!

Snark SN-1 Clip-on Guitar Tuner
Snark SN Tuner

Affordable little tuner with accuracy up to +/- 1 cent. It feels somewhat cheap due to all-plastic build, and it’s powered by a single CR2032 battery.

Korg Pitchhawk 2 Chromatic Guitar Tuner

Korg is a well-known company for most of the people who are into music equipment. Their main focus is on stuff like keyboards and synthesizers, but they also specialize in making guitar equipment – among them a couple of really good tuners.

This clip-on tuner in particular ranks a little bit higher than the Snark. It has a noticeably better build quality, highly adjustable double ball-joint back lit display with a very useful auto-sleep mode for battery saving. It also has a relatively smaller margin of error when measuring notes, which is to be expected for the higher price point. You can use either the piezo sensor or the microphone to tune the guitar, and you’ll need a standard CR2032 battery (included) to run it.

Summary: If you’re looking for a good, relatively cheap long-term tuner – look no further. The Pitchhawk is perfect for someone who doesn’t necessary want to invest too much in their first tuner, and for someone who mainly plays an acoustic or nylon guitar. The tuner also looks simplistic and pleasing and has a very slim profile, which is certainly a plus in our book.

Korg PitchHawk G2 Clip-on Guitar Tuner
Korg Pitchhawk 2

Noticeable step up from the Snark. Accuracy is still +/- 1 cent, and the body is still plastic, but the overall design and the responsiveness of the tuner is better. You’re gonna need a CR2032 battery to power the tuner.

Peterson StroboClip Guitar Tuner

This is as far as we know the only strobe clip-on tuner available on the market. Strobe tuners are the oldest form of electronic tuners, and Peterson has been making them from the very beginning. They use somehow different approach from chromatic tuners, – they compare the note played with a reference frequency, such as the flashing of an LED light, which makes them upwards of ten times more accurate.

The tuning process itself is somewhat different from what you’d encounter on a standard chromatic tuner. Instead of the half-circle with the green LED light on the apex, the display on a this tuner shows a strobe that spins at speed that depends on how far you are from being perfectly in tune.

You’ll rarely get the strobe to stay completely still because a guitar string stays in tune for a fraction of a second before going slightly over and under, – a difference which is undetectable by human ear but well visualized on the display of the StroboClip.

Summary: Peterson StroboClip tuner measures to much greater accuracy than a standard tuner, it doesn’t require silent environment which makes it perfect for gigging players, and the build quality is just amazing! One thing to consider – strobe tuning usually takes a couple of seconds longer, but the whole process for some reason appears to be much more enjoyable and involved.

Peterson StroboClip Clip-on Guitar Tuner
Peterson StroboClip

A huge difference in both the build quality and the accuracy when compared to the two previously mentioned tuners. This beast measures up to +/- 0.1 cent, which is ten times better than most of the stuff on the market. The body is all metal, and feels premium.

Best Pocket-sized Guitar Tuners

We’re not hundred percent sure that there’s actually a name for these types of tuners, but it certainly felt that they needed their own separate category. These tuners are usually battery powered and have both microphone and input-jack. They are targeted at both the electric and acoustic guitar users and they are usually very cheap and small in size, which makes them great for carrying around in your pocket.
Important thing to note is that these tuners work best in a silent environment since most of the people will use the built-in microphone on the tuner, which also picks up all the background noise.

Korg GA-40 Guitar and Bass Tuner

We’ll start of with the Korg GA-40, which is a great entry-level tuner from this category. It’s very small and compact in size and using it is really a no-brainer. You turn it on, play the string, and spin the tuning peg until the needle hits the center.

The built-in microphone is fairly good but requires low-level of background noise, and the input jack on the side works much better in our experience. On the opposite side of the input jack this tuner also has an output jack, which means that you can have your guitar connected at all times without the need the unplug it in order to plug the guitar into an amp.

One thing that’s really cool about the GA-40 (also true to other tuners in this category) is the fact that this is probably the most simple and easy to use tuner out there. There’s no need to plug it anywhere (if you don’t want to), and you don’t have to attach it to your guitar, – it just works. Grab it out of your pocket, place it on your lap, and just tune your guitar. Absolutely no fuss at all.

Summary: This is probably the tuner we would personally recommend to a complete beginner. It’s a little bit “jumpy” but it does a decent job overall and it’s really affordable. Just be prepared to invest a little more time in the process of tuning – as it’s not as reliable as some of the top models.

Korg GA-40 Small Pocket Tuner
Korg GA-40

Pretty much the simplest and and perhaps the most straight-to-the-point tuner on the list. Has both the microphone and an input jack so you can tune your guitar whichever way you prefer. It uses two AAA batteries, and it’s accurate up to +/- 1 cent.

Korg TM-50 Tuner and Metronome

Korg pretty much figured out the game of guitar tuners, since in every possible category they seem to have a contender. This little tuner is basically a pocket tuner on steroids, especially when compared to the previously mentioned GA-40. It’s a little bit more expensive, but that has its reasons as we’ll see.

We personally compared the two together at a local guitar store and the TM-50 seemed to have a much better response when using the microphone, especially while tuning in an environment where there’s lots of people talking and other instruments playing in the background. Tuning directly through a cable seemed to lessen the gap between the two somewhat, but the TM-50 still locked onto a note a lot quicker than the GA-40.

The tuner has both the input and the output jack, which saves you from the hassle of dealing with cables each time you tune the guitar. The display is back-lit, meaning that it’s very easy to read in both daylight and in dark environments, with the option to turn the light off manually to preserve battery. The built-in metronome is somewhat quiet, but does its job well enough. The great plus is the ability to tune to different pitch standards with range from 410-480Hz, apart from the standard 440Hz.

Summary: In our experience this tuner outperforms the GA-40, and as said for these type of tuners, it is just perfect for carrying around in your pocket and just taking it out whenever and wherever you need it. If you don’t care for the small price difference between the two – go for it! The TM-50 feels a lot less cheap, and a lot more like a serious piece of equipment.

Yamaha YT250 Small Pocket Tuner
Korg TM-50

A proper pocket tuner with a lot of additional features. It has a built-in metronome, a back lit display, and allows tuning to different pitch standards ranging from 410-480Hz. It’s powered by two AAA batteries, and you can tune either through a mic or with a cable plugged directly into the tuner.

BOSS TU-12EX Chromatic Tuner

For the most demanding users we initially had three options to consider: BOSS TU-12, Seiko Sat1100, and Korg OT-120 Orchestral Tuner. These are all top of the line tuners made for very precise tuning – not only of your guitar, but also for pianos, violins and other string instruments. We’ve had the Seiko on this list for quite some time, but almost no store has the tuner in stock anymore, so the decision was made to push the Boss into the spotlight (for no particular reason really – Korg is just as good).

Boss TU-12EX Chromatic Tuner is the successor of the widely popular TU-12 model, mainly praised for its analog display – which was luckily carried over to the TU-12EX. The tuner has a physical needle, which is really a cool feature and adds to the overall premium feel of this tuner. The movement of the needle happens in real time, as opposed to “simulated” needles which are limited by segments on digital displays.

The casing on this tuner is build to last and leaves the impression of a very well built product. Tuner of course has both the microphone and the input/output jacks, and it’s powered by two AAA batteries or a power adapter – which is a feature that many among you will appreciate.

Summary: This tuner is clearly made for perfectionists. The analog needle really shows you even the slightest movement of the note, and for that reason alone this tuner is much better than any of the tuners from the bottom range. If you don’t mind the price, and you want something that will serve you for years to come, this is probably the best choice you have in terms of small pocket tuners.

Boss TU-12EX Small Pocket Tuner

Premium pocket tuner with an analog display, built-in mic, and standard +/- 1 cent accuracy. Powered through two AAA batteries, with the option to use a power adapter instead (not included).

Best Stage (Pedal) Guitar Tuners

This category of tuners is particularly popular among professional guitar players who often play on stage. They fit quite well on a pedalboard, and they are made for hands-free use. If you’re often playing while standing, or you just want something that offers you the quickest and most comfortable way to tune your guitar, this category of guitar tuners is probably best for you. Be aware though – none of the tuners listed have a microphone so they can’t tune an acoustic or a classical guitar that doesn’t have an output.

Korg Pitchblack Tuner Pedal

Again something from Korg. This time a compact stage tuner which offers pretty much everything an average user would ever need. It comes in a very sturdy die-cast case which holds a bright and a very readable screen with a couple of different display modes. The Pitchblack is powered by either a power adapted or a 9V battery. It’s smaller in size when compared to most of pedal tuners, which is good if you want something that will not take a lot of space on your pedalboard.

The tuner also features a true bypass, which means that when the tuner is off it won’t mess with your sound in any way, but pass it straight to whatever is next in the chain. When the tuner is on it will automatically mute the guitar signal, so you won’t feel like an annoyance to the people around you.

Suumary: The Pitchhawk tuner is simply amazing when you consider what you’re paying for it. The quality of the case itself, and the precision that this tuner offers makes it a great value. Consider it an entry-level model and ticket to the world of professional guitar gear.

Korg Pitchblack Pedal Guitar Tuner
Korg Pitchblack

Affordable pedal/stage tuner with the most basic functions. It features true bypass, a well built die cast aluminum body, and a great display easy to read from a relative distance. At this price, it’s a steal.

TC Electronic Polytune 2

The TC Electronic Polytune is as straight-forward as a guitar pedal tuner can be. You press the switch with your foot, pedal mutes the guitar sound, and you turn the tuning pegs until the green line hits ninety degrees. But there’s something that separates the Polytune from the bunch, and that feature becomes evident when you strum all strings at once.

The Polytune not only allows for the individual string tuning, but also enables you to tune all six strings at once. When you strum your guitar the tuner automatically switches from chromatic to polytune mode, and you’re presented with six green dashes, each representing a string on your guitar.

For finer tuning and setting up the intonation of your guitar, the Polytune also has a virtual strobe tuning mode. This increases the accuracy to up to ten times compared to the standard mode.

As a side note – if you happen to prefer a clip-on tuner, TC Electronics recently released a PolyTune Clip tuner which offers the same features as this tuner, but it’s targeted at acoustic guitar users. The price is usually around $50.

Summary: For someone not suffering from the need to buy everything Boss, Polytune objectively offers a better product for a considerably smaller price. It allows you the quickest and the simplest way to tune your electric guitar, it features true bypass, and the overall design and build quality of this pedal tuner leaves very little to be desired.

TC Electronics Polytune Pedal Guitar Tuner
TC Electronic Polytune 2

Allows you to tune all strings at once, and offers up to ten times more accuracy (+/- 0.1 cent) than a standard tuner while using the strobe mode. The body is die-cast aluminium, and the tuner features true bypass.

Boss TU-3 Chromatic Tuner Pedal

Of course – this review can’t go without the famous Boss TU pedal tuner. This particular model is the successor of the widely used TU-2, which probably is/was on most of the famous guitar players’ pedalboards. Thing that makes this tuner so popular is probably the classic and timeless design of the pedal itself, which is a great plus if you want it to fit well with the rest of the pedals on your pedalboard.

Another thing that separates the TU-3 from the rest is the display, which is readable even in the bright sunlight (to some extent of course) making it a perfect choice for professionals who often play on outdoor stages. The previously mentioned Korg Pitchblack surely lacks in this aspect, and the TC Polytune too could use a brighter display.

When compared to those two tuners, the TU-3 lack true bypass but features a buffer that eliminates the possibility of the tone getting sucked by long cables (most of concern just to professional guitarists – you can read more about it here Buffered vs. True Bypass Pedals).

Summary: Even without professionals endorsing it, the Boss TU-3 can stand on its own legs. It’s build to last, it’s very simple to use, it doesn’t try too hard to leave an impression in terms of the design, and it’s probably one of the best tuners to be used on stage.

Pretty much the industry standard. The tuner uses a well-known design language that many will appreciate. The body is sturdy and built to last. No true bypass, but the tuner features a buffer that eliminates the possibility of the tone getting sucked by long cables.

Peterson VSS-C Strobo Stomp Tuner

Realistically the tuner that deserves this place the most is the Peterson AutoStrobe 490, but due to limiting ourselves to a more moderate price point of around $200 (compared to $700 for the AutoStrobe), we decided to choose a different model.

As we said previously, Peterson is pretty much the mother-of-all when it comes to modern guitar tuners, so it shouldn’t be a surprise that they have something on their shelf that has premium written all over it. Their Strobo Stomp tuner is extremely accurate and quick to lock onto a note, and it’s heavy and big – leaving the impression of an expensive and a true premium product.

Next to that, the tuner is equipped with a ton of features. Peterson packed the Strobo Stomp with twenty five “sweetened” tunings – among them the Buzz Feiten system for both guitar and bass, and presets for steel and bluegrass guitar. The pedal can also operate under three different settings: monitor, true-bypass, and active DI (with XLR output).

Summary: The Strobo Stomp is the tuner that you should consider seriously if you’re really focused on being perfectly in tune, or you’re someone who plays, builds, or fixes guitars professionally. Only other tuner that can stand by its side is the Turbo Tuner by Sonic Research, which promises stunning accuracy of +/- 0.02 cents (probably to take the KOTH title at some point in the future).

Peterson VSS-C Strobo Stomp Pedal Tuner

A beast that will tune well beyond the accuracy of a standard tuner (+/- 0.1 cent). It features die-cast body, strobe tuning, true bypass, and built-in presets. Perfect for studio use, and for perfectionists.
