While electric guitar tuners get the pitch of your guitar via the output signal, acoustic guitar tuners rely on audible sound or wood vibrations to monitor your intonation. This presents a challenge and at the same time provides practical advantage - the obvious challenge is not being able to silently tune your guitar, while the main advantage is flexibility because they will work on virtually all instruments that produce sound or vibrations. To hear the sound of your guitar, acoustic guitar tuners are usually equipped with a built-in microphone and piezo sensors that can pickup the string vibrations through the wood when the tuner is attached or clipped to the guitar.
1. Clip on Tuner
These are sometimes also called a 'piezo tuner' because they use a piezoelectric sensor which, when attached directly to your guitar, is able to pick up the vibrations of the strings directly through the instrument. The advantage of this design is to let you tune your guitar in noisy venues, the surrounding sound causes almost no interference with your tuner. These usually clip on to the headstock where the tuning pegs are, although some are designed to attach to the top of the guitar body.
The downside with these is that you can't use it to tune other acoustic instruments like brass or woodwind unless the tuner also has a built in microphone, and you may not like the look of them hanging off the end of your guitar.
The clip on tuners we recommend:
This is one of the most feature-packed and versatile clip on tuners available, ideal for multi-instrumentalists and guitarists who use multiple tunings. It works just as well with other stringed instruments including Banjos, Ukuleles, Mandolins, and Dobros. It also has special settings for alternate tunings and capos making it well suited for live performance where you need to make tuning changes quickly.
On top of its versatility, the StroboClip is known for its impressive 1/10 cent accuracy, allowing you to tune your instrument as precisely as possible. This tuning accuracy is then paired with the alternate temperaments and tunings that are meant to cover various string and wind instruments. Note that it can even handle guitars with the Buzz Feiten Tuning System, and it can all be done conveniently via the easy to use display and controls. Another nifty feature of this tuner is the battery saving auto-sleep and auto-power-off functions.
The StroboClip costs more than other tuners in this category, and one of the main reasons is that it uses a proprietary virtual form of Strobe Tuner technology which provides its extremely high levels of accuracy (click here for an explanation on strobe tuners). The MSRP is $89.99 but many online stores sell it for $79.99. See Peterson for further details. Get the latest price & reviews at Sweetwater.com
The Korg GripTune is a compact chromatic tuner that lets you tune accurately as possible, down to +/- 1 cent, without the usual bulk and weight. It does not have too many extra features, but you'll get essential tuning functions, and this makes tuning quicker and hassle free.
It's small size and monitoring flexibility makes this easy to recommend, you can easily clip it on any type of headstock, adjust the screen position where you can view it properly and tune away. It is also designed to be discrete, giving you a good view of the screen while staying largely hidden from the audience's point of view. This means that you can tune your guitar in virtually any position, be it when you are standing, kneeling or sitting down.
If you are looking for a stress-free no-nonsense clip-on tuner, then you would appreciate the GripTune, especially when you see its truly affordable price tag. You can buy it online for around just under $16. See Korg for the full specs. Korg also makes a great headphone amp. Get the latest price & reviews at Sweetwater.com

It starts off as a versatile all-instrument tuner, you can clip it on virtually any instrument and it will give you accurate reading. The Snark SN-2 has both a vibration sensor and a built in microphone so you can use it to tune regardless of the instrument or situation.
It's solid performance is matched by its impressive visuals. The tuner's full color back-lit display can be rotated through 360 degrees for easy viewing, while the clipping mechanism is designed to stay put while you change the viewing angle - and it does so without damaging your precious instrument.
Other features include alternate tuning settings and pitch calibration (415-466Hz). Interestingly, the tuner comes with a tap tempo metronome, a feature that is not found on other tuners. This adds even more value to the already value-packed Snark SN-2, and makes it a useful practice companion. The MSRP is $39.99, but you can usually get it for less than $12.99 online.

2. Acoustic Tuner

4. Guitar Tuner Facts & Definitions
- Automatic tuner - this is an easy guitar tuner to use because you don't have to tell it which note or string you are playing, it will work it out by itself and tell you which note is sounding and how sharp or flat it is. There are still some older types on the market which require you to tell it which note you want to tune to - we don't recommend you buy one of those and we haven't mentioned any above.
- Chromatic tuner - Some guitar tuners can only tune the 6 notes of standard tuning - i.e. A E D G B E. A chromatic tuner can automatically tune to all 12 notes in the scale making it much more versatile in that you can use alternate tunings and tune other instruments.
- Cents - A measurement of interval which is exactly 1/100th of a semitone. Although most people can't hear the difference between two successively played notes if the difference is less than 6 cents, you still need to tune to an accuracy of less than 2 cents. E.G. if one string is 5 cents below correct pitch, and another is 5 cents above, then the difference of 10 cents will sound out of tune. The accuracy of guitar tuners is measured in cents.
- Online Tuner - Many of these just play a tone for you to listen and tune to, they don't tell you the pitch of your strings (click here for an example). Although these can be good for experienced musicians, we don't recommend a beginner use this type of tuning method.
- Temperament - This is basically a particular tuning, different temperaments may have different ratios between intervals. This is an advanced topic - for the best explanation see Wikipedia
