Be it for fun, practice, for a weekend gig or for a big open air concert, you need to keep your guitar in tune.
To do this you need a reliable, convenient and accurate tuner. And to help you in finding just that, I present 11 of the best acoustic guitar tuners, chosen based on my many years of experience, for their functionality, durability, positive feedback and user recommendations.
The Different Types of Acoustic Guitar Tuners
Tuners come in various shapes and sizes, but they can be classified under three groups based on their form factor and how they listen to your guitar's tuning. The three main groups include clip-on tuners, acoustic tuners and pedal tuners. Note that some might fall under multiple classifications, especially those intended for use with various types of instruments.
Without a doubt, Clip-on Tuners are the most popular of all the three types, thanks to their ease of use, practicality and flexibility. After clipping them on the headstock, they utilize "piezo" sensors to hear your guitar sound via the vibrations of the wood, instead of having to rely on a microphone or an input jack. This means that you can tune your guitar in situations where noise from other instruments are unavoidable. While they can be fragile and tiny, they can get the job done with proper handling. More importantly, these tuners are more affordable and they reduce the bulk and weight that you have to carry to your gigs.
Because they utilize built-in microphones, Acoustic Tuners rely on actually hearing the sound of your instrument, it's as if a professional musician is helping you tune by ear. The obvious challenge for this type of tuner is that outside noise will easily bleed into it's microphone making it hard to use when tuning with other musicians or at noisy gig venues. While this particular technology may seem outdated, they remain the most flexible because you can use them to tune almost any instrument.
Pedal Tuners with their tank tough metal exterior are the most reliable and durable of the three, making them ideal for gigging musicians. While they maybe bulkier and heavier, the extra protection, better accuracy and bigger display area that they offer, can often spell the difference between a great gig and a gig gone wrong. It's also worth mentioning that its harder to misplace pedals, so you won't end up having to tune on stage by ear! These are only of use If you have a pickup in your guitar or you're using an acoustic-electric and you don't mind having an extra pedal in your rig.
What to Look For When Choosing Which Acoustic Guitar Tuner to Buy
Tuning in smaller venues is one of the many challenges that gigging acoustic guitarists have to face on a regular basis. Since you can't totally mute an acoustic guitar's natural projection, the audience can still hear you pluck your strings as you tune. Although cracking jokes can help distract your audience from the awkward "tuning song", you often have to soften your attack on the strings as you tune so they don't over power your banter with the audience. In line with this, you need a tuner that is sensitive enough to let you tune with the slightest pluck or strum, and you also want it to be as easy to use and discrete as possible so you can transition to playing a song quickly. Clip-on tuners, and acoustic tuners work well for these intimate gigs.
In louder band settings or for bigger venues, tuning silently becomes less of a problem, but tuning fast and accurately is demanded, especially when multiple instruments are tuning at the same time and you can no longer trust your ears. These situations require tuners that will let you tune quickly and accurately without having to actually hear the notes yourself. For these types of gigs, you are better off using pedal tuners since you'll probably be plugged into an amplifier or a PA anyway. Clip-on tuners with bigger displays also work well in this situation.
There are also many tuner apps for smartphones - they're often free which makes them perfect for using at home, but they're far too cumbersome and prone to audio interference to use when playing live or at important rehearsals with a large number of other musicians.
Tuners for Electric Guitars
The clip-on and pedal tuners in this guide can be used for tuning electric guitars, as can any of the ones listed in the acoustic section where they have a 1/4" input. If you would like to see a more general guitar tuner guide, which also includes rack-mount tuners, then we suggest the Guitar Tuner Guide on Gearank.com.
Here are The 11 Best Acoustic Guitar Tuners
TC Electronic PolyTune Clip
Manufacturer: TC Electronic | Price: usually about $50
TC Electronic’s innovative polyphonic tuning allows you to strum the guitar and concurrently tune each string instead of the usual one-string-at-a-time method.

Now this same technology is made available in clip-on format, carrying over the same tuning precision and innovative multi-string tuning but in a more accessible and affordable format.

One thing that TC Electronic can improve on is the clip mechanism's limited rotation, which makes it a bit harder to get the tuner into certain positions. Other than that, if you want no less than the best tuning technology then you should get the PolyTune Clip. Get the latest price & reviews at Amazon.com.

Boss TU-12EX Chromatic Tuner
Manufacturer: BOSS | Price: usually about $99
Known for their tank tough and affordable pedals, Boss makes equally reliable and durable acoustic tuners. The Boss TU-12EX Chromatic Tuner is the updated version of their popular TU-12, which some professional musicians have been using for more than 10 years. The update adds pedal tuner like qualities with the addition of input and output jacks for acoustic-electric and electric guitars. There's not much extras in this unit, just a straightforward acoustic tuner with meter display that can handle the frequency range of guitar or bass from E0 (20.6Hz) to C8 (4,186Hz). What makes this stand out is how it does what it does reliably for years - and it does so with good precision of +/-1 cent. The meter display maybe old school but it shows you exactly how close you are from your desired tuning. Ironically, the TU-12EX did not follow Boss' usual affordable price point, well at least when it comes to tuners. Still the price is steal considering the lifetime's worth of tuning you can get out of this box.

Of the many chromatic tuners in the market, the KLIQ MetroPitch is one of the few hidden gems that give you the best value for your hard earned money.

The ability to behave like a pedal and acoustic tuner is complemented by the wider tuning range of A0-C8, making it usable for bass, guitars and other instruments. The Tap Tempo metronome is an added bonus that surprisingly works really well, with an intuitive jog dial interface that lets you adjust the tempo in real time to your preference. Finally, the 88 Note Tone Generator is ideal for ear training, and can be used as reference notes for alternate tuning. My only concern is that some extra handling care maybe needed to extend the lifetime of this multi-purpose tuner. Still this is the best practice friendly tuner in this list, ideal for serious students of the instrument. Get the latest price & reviews at Amazon.com.

Boss' reputation for building gear that last a lifetime is without question, and this applies to their popular chromatic tuner pedal, the TU-3.

Korg Pitchblack Chromatic Tuner
Manufacturer: Korg | Price: usually under $80
While more popular with electric guitar players because of its black motif, Korg's Pitchblack Chromatic Tuner works just as well for acoustic-electrics guitars. Its road tested exterior makes it more than capable of handling the rigors of regular gigging, and its ability to handle downtuned electric guitars and even bass makes tuning acoustic guitars a breeze. The black color is not just for show, because it creates a better contrast for the eleven segment LED meter to shine through, along with large note name display, regardless of light setting. Having said all that though, the Pitchblack pedal is easily the most visually striking among the tuner pedals listed, and can be an easy pick for many based on looks alone. Giving you the incentive to utilize precious pedalboard space on a tuner, Korg equipped this pedal with DC output which you can use to power up your other pedals. Like the Boss pedal, Pitchblack can double as a power supply, making the cost of acquiring one even more justifiable. While it could have been better if it had more features instead of the redundant display options, this workhorse tuner pedal will make a great addition to anybody's rig.
