You need to find one that is fast and easy to use, so it is important to do some research and see what tuners will work best for your needs. Here are a few tips on buying a tuner, and a few reviews to help you start your search.

Types of Tuners

There are a lot of choices when it comes to tuners for a guitar or bass that range from simple tuners to complex devices.

Electronic tuners – You will find a wide variety of electronic tuners that you can use with a guitar. Some will detect the vibration of each string to help the guitarist get in tune. Other tuners will use both of the methods of tone detection.

Tuning forks – When you strike a tuning fork, you will hear the “A” note. You can then tune your string to that pitch, and then tune the rest of the strings in relation to the A string. This can be a challenging process for students, and it is also hard when performing in a noisy setting.

Pitch pipes – When you blow a pitch pipe, it will emit six different tones that correspond to the six strings on a guitar. This is also challenging for students, and it is difficult to do in a noisy setting.

Tone generators – These can be used when you are tuning acoustic instruments like brass, wind, percussion, or stringed instruments. Tone generators include tuning forks and pitch pipes that were created to be used with a specific instrument like a violin, cello, or ukulele.

Chromatic tuner – This type of tuner can also tune an acoustic instrument – if it is outfitted with a microphone that can detect the sound of the instrument. These devices come with a wide variety of features that are sometimes adjusted to work with specific instruments or instrument families.

Types of Electronic Guitar Tuners

Clip-on or headstock tuners – This type of tuner clips onto your guitar or bass headstock, and it can detect each string’s tuning through the vibrations of the instrument. Some of these clip-on tuners have an internal mic that permits the acoustic tuning of a wide variety of instruments. It is typical of them to be able to swivel, so that you can see them easily, and some of them are created to work alongside stringed instrument and other assorted wind and brass instruments.

Pedal Tuner – This type of tuner is housed inside a case that you can rest at your feet, making it perfect for discreet use by a performer. They have displays that you can read easily in a dark venue.

Multi-Effect Pedals – Many of these types of pedals come with tuner capabilities as one of their function.

Rack and Tabletop Tuners – There are many types of these tuners on the market with features to fit your needs and price points that will fit your budget. Some are very sophisticated, and they are used in stage rigs and studios. Other simpler tuners will be able to give you all of the basic tuning functions that a guitar will need without a lot of added features.

Built-in Preamp Tuners – Preamplifier circuits of some acoustic-electric guitars and a couple of electric guitar models have a tuner built into them. There also some guitar amplifiers that come with a tuner function. Since they are built in, they are extremely convenient, and some even let you tune silently, which is helpful when you are performing, or are in a noisy setting.

Apps – There are also many apps that you can download if you have an iOS or Android smartphone that will let you perform chromatic and guitar tuning. These tend not to be as accurate as the other tuners.

Features and Functions

It is important to know what features are available on current tuner models that are on the market, and whether or not you need those features with playing style and skill level. Make sure to do your research and keep your budget in mind while you are shopping.

Displays/meters – One of the most important features of a tuner is the ability to see the information that the tuner is giving you. If this information is not legible or clear, the tuner is not really helping you. Some models have a needle-based meter that will show you how close you are to the pitch while you are adjusting the tension on your string. Some use LCD displays with a needle-like graphic or a LED light that will change colors as you get closer to the right pitch.

Many of these displays will also use colors to show that you are flat or sharp, and they will display the string that is currently being tuned. Many of them can even help you fine tune your guitar or bass, and some of the most advanced models use strobe technology that shows you in real time. Always think about where you are playing and consider whether having a brightly lit display will help you on a poorly lit stage.

Auto pitch detection – Some of the high-quality tuners will tune automatically, identifying the played tone and indicating how relative it is to the true pitch. Lesser-quality models will require you to set a target pitch for each of the strings.

Special tuning modes – Optional tuning modes on many digital guitar tuners can match certain instruments like a baritone and 7-string guitars or 6-string basses. Some of these tuning modes also back drop tunings based on “D” or “Eb”, popular in rock and heavy metal and rock, instead of the typical “A” reference. Look for a tuning model that supports capo tunings if you use a capo. Also, it is possible to find a lot of alternate tuning modes as well as various tempered scales on more elaborate guitar tuners.

Microphones and speakers – Microphones that are placed on tuners will distinguish an instrument’s acoustic tuning. This is convenient for a wide variety of instruments, especially those that have a built-in amplifier and speakers that make audible tones – handy when you are developing an ear for intonation.

Metronomes – Many tuners also have a metronome function that makes them perfect for students.

Bypass/silent tuning – The bypass features of pedal tuners doesn’t color the signal that it send to the amplifier. Silent tuning avoids the amplifier’s output or sound system, and it lets you tune by just referencing the visual display on your tuner.

Runner Up: Sonic Research Turbo Tuner ST-300

View on ReverbView on Amazon

The Sonic Research Turbo Tuner ST-300 is advertised as a “true stroboscope” tuner that is very precise, but it is not widely available. A mechanical strobe tuner operates with the input guitar signal driving a strobe light that will light up a rotating disk. When the guitar signal frequency equals the rotating disk speed, the rotating pattern will look like it is standing still indicating that the tuning of the note is correct.

The slightest discrepancy is shown by a strobe tuner between the reference frequency and the note you are playing making it a lot more precise than the needle type of tuner. The only difference between a mechanical strobe tuner and the ST-300 is that the ST-300 does not have a rotating disk.

The Turbo Tuner ST-300 is durable and it has a utilitarian appearance, but it gives the look of more usability instead of just a neat gadget. It has a die-cast aluminum MXR-style with a true bypass footswitch. There is a ¼” IN and OUT jack on each side, and the output is muted when you are operating the tuner. There is a jack for the optional 9V DC power supply on the rear of the pedal, and the power supply allows you to power other pedals and create a daisy chain.

You will also find a micro USB port that will allow you to do customized tunings on your computer. You can also alter your tuning setting with the CAL and FLAT modes of operation.The Sonic Research Turbo Tuner ST-300 gives you +/- .02 cents accuracy, which is the best you can get with a pedal tuner.

It has a bright display, but not bright enough for extreme conditions. The LED pattern will rotate right is your note is sharp, and rotate left if your note is flat. When the pattern does not move, your note is in tune. If you are used to the needle-type of tuner, this strobe-style display will take a little getting used to. The CAL button is also available to change the A4/440.0 Hz reference frequency if you prefer.

The ST-300 has several customizable features, and it can assist with several temperaments including just, equal, and Pythagorean, plus alternative tunings like drop D, open D, open A, and DADGAD, 5 string bass, violin, cello, bass, and bass drop D.

You can also make setting adjustments that can take more time by pressing mode buttons when the pedal is powering up. You just need to remember the right order of button presses. Most importantly, it will remember your settings once it is turned off. This is a super-fast tuner with zero lag.


  • Very responsive and accurate
  • Will remember your settings once it is setup
  • Super-fast tuner, notes appear immediately
