Our Top Picks for the Best Guitar Tuner of 2021
Without further adieu, lets take a closer look at these tuners you can buy today.
Clip-on tuners were all the rage when they debuted around a decade ago. The unfortunate truth is that virtually all of these tuners were cheaply made and inaccurate. Fortunately, some clip-on tuners, like the UberTuner from KLIQ, deliver impressive performance and accuracy at a bargain price.
The Ubertuner features a piezo sensor that’s accurate to within +/- 1 cent, an easy to read color display, an articulating screen that can be positioned at any angle, and an improved clip that secures the tuner to your headstock without marring your guitar’s finish.
While it’s intended for guitarists, the UberTuner also has modes for bass guitars, violin, ukelele, and a chromatic mode for tuning virtually any instrument. Other notable features include Bb, Eb, F and D transposition settings, a power-saving mode for extended battery life, and a 3V lithium battery.
- Very accurate for a clip-on
- Easy to read display
- Power save mode preserves battery life
- Larger than most clip-on tuners
- Articulating screen can move out of view when playing live
Peterson has been the industry standard in tuning accuracy for decades, and they’re bringing their cutting edge technology to the masses with their StroboCLIP tuner. While Peterson’s tuners are some of the most expensive in the business, their StroboCLIP tuner is available for less than the cost of a decent pedal tuner.
The StroboCLIP offers precision accuracy to within +/- .1 cent, a wide tuning range of C0-B6 and a transposition range of -4 to +7, plus transposition to keys C, F, Bb, and Eb. Where the StroboCLIP shines is when it comes to alternative temperaments and sweetened tunings.
The StroboCLIP offers 50 different sweetened tunings and 11 historical temperaments.
The StroboCLIP also offers input for a piezo pickup and a micro-USB port for upgrading the tuner’s firmware so that you can stay on the cutting edge of whatever Peterson is offering. For players who need precision accuracy without breaking the bank, the StroboCLIP is a top choice.
- Unbeatable accuracy
- Tons of sweetened tuning and temperament options
- LCD provides perfect visibility in dark or bright environments
- Expensive for a clip-on
- Clamp doesn’t work well with classical guitars
Snark ushered in the clip-on tuner craze, and they’re one of the first and most well-known tuner brands. Their HZ1 tuner has built a cult following because it’s every bit as accurate as other Snark clip-ons, but it has a much smaller footprint than their larger offerings.
The HZ1 is 40% smaller than Snark’s previous models, and a newly-designed clip is virtually unbreakable and compatible with practically any instrument. This tuner offers Hertz tuning, but it doesn’t quite boast the same accuracy as more expensive clip-on tuners.
If you’re looking for the most affordable tuner possible, the HZ1 will be a strong fit for you. But, you’ll be sacrificing some quality and accuracy in the process.
- Smaller than other Snark tuners
- Easy and intuitive single-button operation
- Compatible with any instrument
- Mediocre accuracy
- Only has basic features

There are specific modes for guitar or bass, and a chromatic mode for tuning any instrument. The TU-3 also offers support for 7-string guitars and 6-string basses, and flat mode for drop tunings up to six half-steps below standard.
The TU-3 is accurate within +/- 1 cent, which is considered the industry standard by most guitarists. A strobe tuning mode allows players to dial in their tuning with even greater accuracy. For guitarists who run large pedalboards, the TU-3 can provide power for up to seven pedals, eliminating the need for a large power supply in many cases.

Thankfully, we live in a world where strobe tuning technology can be applied to a tiny pedal tuner, allowing guitarists everywhere to play in perfect tune.
The StroboStomp is accurate within +/- .1 cent, it supports 135 sweetened tunings, and it has an incredible range of C0-A#8. It’s impossible to find a tuner that’s as accurate or as full-featured as the Strobostomp.

The PolyTune 3 from TC Electronic is far and away the most unique guitar tuner on the market. Unlike other tuners that tune a single note at a time, the PolyTune 3 can tune multiple pitches.
While polyphonic tuning is cool, it isn’t for everyone, so the PolyTune 3 provides additional modes from chromatic and virtual strobe tuning. The chromatic mode is accurate to within .5 cents, and the virtual strobe mode delivers impressive +/-.02 accuracy.
An ultra-bright 109 LED display ensures you have no trouble seeing the tuner and an ambient light detector that adjusts brightness to match your lighting conditions.

Selecting the Best Guitar Tuner: Buying Guide
Before you head off to buy your new tuner, it’s a good idea to consider a few different specs and features that will make choosing the best tuner for the way you play much easier.
What are the Different Types of Tuners?
Guitar tuners usually fall into three different categories: chromatic, polyphonic, and strobe.
The most common and popular guitar tuner, chromatic tuners automatically recognize any of the 12 pitches in the chromatic scale.
These tuners are a practical option because they allow you to easily set your guitar up to play in any tuning, as long as you know which notes make up the tuning. Many chromatic tuners have additional modes for drop and alternate tunings.
Polyphonic tuners are a fairly recent development, and only a few manufacturers have polyphonic tuners available. TC Electronic pioneered this technology, and it allows players to tune every string on the guitar at once instead of plucking the strings individually.
They’re certainly interesting, but the technology is still in its infancy, and polyphonic tuners tend to be less accurate than standard chromatic tuners.
Strobe tuners are the most accurate tuning option, so they’re favored for studio applications, and they’re an essential tool for luthiers, who can set a guitar’s intonation dead perfect with the help of a strobe.
Until recently, these tuners were desktop-sized, so they weren’t practical for gigging, but virtual strobe technology has made it easy to harness the accuracy of strobe tuning for practice and gigs.
Tuners are available in several configurations, and depending on how and where you play, one style will probably be the best fit for you.
Pocket tuners are affordable and accurate, and their small size makes them ideal for practice, lessons, and storing in your gig bag, so it’s always ready to go.
Pocket tuners typically feature a single input, and some have additional modes and features for calibration, alternate tunings, and altered temperaments.
Clip-on tuners are a relatively new style of tuner, and they’re useful in virtually all situations. These tuners feature a small display mounted to a clip which is placed on the headstock of the guitar. The tuner reads the vibrations of the wood and provides a readout so you can tune the guitar.
These tuners are available in chromatic and strobe styles and they’re compatible with most string instruments and virtually all guitars. These tuners are surprisingly accurate in quiet environments, but if you’re in a loud room, the tuner will pick up other vibrations, so these aren’t a good choice for most gigging musicians.
Pedal tuners are favored by gigging musicians since they allow for hands-free operation and can be incorporated into a pedalboard.
Pedal tuners feature an input and output and usually feature a mode for silent tuning. Some of the best pedal tuners can also provide power for several additional pedals, so they’re perfect for guitarists who use a pedalboard since you can cut back on power supply cables.
Popular with bass players and for recording applications, rackmount tuners fit inside of a rack housing, and they feature a huge LED display that’s visible from outer space. These tuners provide the same functionality as a pedal tuner but in a different shape.
How to Choose a Guitar Tuner
Here’s what you need to consider before choosing a guitar tuner.
How Will You Use Your Tuner?
Knowing how you’ll use your tuner makes it much easier to find the best guitar tuner for you. Are you a gigging musician? A bedroom rockstar? A student?
If you play live, especially if you’re playing in a band, a pedal tuner is going to be the best option for you. But, if you need a tuner for your bedroom, or for jamming or taking lessons, a pocket tuner or clip-on may be the best choice for you.
If you aren’t sure which type to get; investing in a pedal tuner is always a sound choice. Pedal tuners are nearly as portable and practical as a pocket or clip-on tuner, and they’re the best choice for playing live.

What’s Your Budget?
Guitar tuners range widely in price. Some of the best guitar tuners can be had for as little as $10, while the top of the line strobe models can cost $300 or more.
The price variance of guitar tuners is mostly because of the style of guitar tuner, as pedal or rack tuners are much more expensive to make than clip-on or pocket styles.
More expensive tuners also offer additional features, like support for altered temperaments, alternative and drop tunings, and a variety of tuning modes and display options.

Tuner accuracy is measured in cents, which indicate how sharp or flat your guitar is compared to the proper pitch. There are 100 cents in a semitone, or ½ step, and most people can’t pick up on differences of less than a few cents in either direction, but that doesn’t mean that accuracy isn’t a crucial concern.
The more accurate the tuner is, the better. Keep in mind that the most precise tuners (accurate to within +/- .1 cents) are usually much more expensive than less accurate tuners. A tuner that’s accurate to within +/- .5 cents is often a solid choice for guitarists.
