It may not be the sexiest bit of guitar gear you’ll ever own, but a tuner is a must-have for any serious guitar player. Whether you play electric, acoustic, or bass an out-of-tune instrument will stick out like a kazoo in a string quartet, which is why you’ll want to grab one of the best clip-on guitar tuners to ensure you stand out for the right reasons.

Clip-on tuners detect the vibrations through your instrument when you strike the strings, which makes them much better than that free phone app when you try to tune up at a show or during a noisy rehearsal. They’re typically attached to your headstock so they don’t get in the way of your playing, making them a great option for guitarists looking for something lightweight and easy to use.

We’ve put together a huge range of clip-on tuners for you to pick from, no matter what your budget, but if you’re looking at a tuner for the first time, then be sure to check out our buying advice section at the bottom of this article. For those who just want to see the top clip-on guitar tuners available today, keep scrolling for our top picks…

You'll need to pay more than the competition for the extra accuracy here 

The 0.1 cents accuracy of the StroboClip HD is unrivalled in the clip-on tuner field, so if it has to be perfect, this should be top of the list. Peterson has a great reputation in the industry for build, feature and accuracy; the StroboClip HS delivers on all three fronts.

The large HD screen is an attractive proposition and with the amount of features on offer here, you'll need it to keep track of things. In addition to settings to accommodate drop tunings and the use of a capo, Peterson offers over 50 of its 'sweetened tunings' to allow players to access custom tuning presets to accommodate types of instrument (including a specific preset for acoustic guitar) and even the types of chords you may be playing - such as a bias to making major or minor chords intonate better.

We all want to keep our guitars looking good, so the small size of the NS Micro Tuner doesn't get in the way of that. But it also offers everything you need from a clip-on guitar tuner. 

Its screen can rotate 360 degrees and works effectively at the front or rear of your headstock to be even more discrete. It doesn't scrimp on features either with various calibration modes and a visual metronome. Moreover, it's sensitive response will make it a go-to accessory you'll use everyday.

Best clip-on guitar tuners: TC Electronic Polytune Clip

The best value polyphonic clip-on tuner

Specifications

Price: $49/£33/€40
Accuracy: +/- 0.02 cent
Modes: Polyphonic, chromatic, strobe

Reasons to buy

+
Two tuning modes 
+
Great tuning accuracy in chromatic mode
+
Bright and clear display

Polyphonic response can be a bit hit or miss

TC Electronic turned heads (and ears) when it unveiled its PolyTune pedal in 2010, five years later the Clip continued that good work and it remains a popular option for players with impressive +/- 0.02 cents accuracy in strobe mode and 0.5 cents in chromatic mode. 

This is combined with a clear and vibrant LED screen and the polyphonic functionality will reveal which of your strings are in and out of tune by simply strumming your strings. 

Another handy feature is auto orientation; if you're left-handed or use the PolyTune Clip at the back of your headstock, the display flips accordingly. But we found the polyphonic accuracy a little hit and miss at times in comparison with the pedal version (it will sometimes say your tuning is out when the chromatic mode says it's in tune) . 

The larger size of the Clip also won't be for everyone, but with its two different tuning modes and bright display, this will suit many players.

4. Snark ST-2 Super Tight

One of the best budget tuners that handles the basics

Type: Clip-on chromatic tuner
Tuning range: Not specified
Calibration range: A4 = 415Hz-466Hz
Accuracy: Not specified
Modes: Microphone/vibration chromatic mode / metronome

Reasons to buy

A reasonably-priced clip-on tuner

+

-
Not exactly discrete 

Snark has long been a name to trust when it comes to guitar tuners and the ST-2 is a no-frills, reliable approach that should please a lot of players. 

Though its accuracy isn't stated in specs, we found performance was good with swift tracking. You can choose between a mic or vibration sensor with the former a preferred option for acoustic instruments in quiet surroundings, while vibration is practical in noisier locations, and with electric guitars and basses.

The screen is bright, easy to read and angled for good visibility – and with instrument design varying, this offers flexibility that's very welcome at an affordable price.

If you want more accuracy there are (pricier) alternatives 

Like TC Electronic and Peterson, Boss is a company with a very strong reputation for quality tuners – specifically the TU series of pedal tuners pedal tuners. So we're pleased to see a Boss clip-on model being offered at such an accessible price-point. 

The TU-02's bright screen offers good contrast and visibility, especially considering the impressive 24 hour battery life. This is aided by the tuner's auto power-off feature if you forget to power it down after tuning up. 

The choice of chromatic tuning mode, alongside modes for guitar, bass and ukulele is also pleasing to see at this price-point, making this a great buy for general use, or something to store in your gigbag.

Accurate tuning with a dollop of fun

Price: $79/£73
Modes: Chromatic, strobe, polyphonic
Tuning range: A0 (27.5Hz) –C8 (4186 Hz)
Calibration range: A4 = 436Hz–445Hz
Accuracy: +/- 0.1 cents (strobe mode)

Reasons to buy

+
Very high accuracy
+
Alternative tuning animations add some fun
+
The chord finder is an unexpected bonus

Reasons to avoid

-
Pricey, plus bass players need to buy a separate OTB-POLY model

You might be surprised to find just how many guitar tuners Korg now offers – but this has to be the most impressively featured of its clip-on models. The OLED screen here and 11 tuning animations are a sign of the premium quality – and there's more.

The +/-0.1 cent tuning accuracy puts this in the pro-level category of headstock guitar tuners, and it offers memory backup for your settings. But it's fun too to brighten up the often mundane task of tuning with animations featuring cats and taps if you want a break from needle and strobe modes.

In addition to the polyphonic tuning, there's a chord finder feature here; it will tell you the chord you're playing and even works with a capo up the 7th fret. Neat!

Modes: Chromatic
Tuning range: A (27.5Hz)-C (4186.0Hz)
Calibration range: A4 = 440Hz
Accuracy: +/- 1 cent

Light and minimalist…

But with a display that maximises the size
+
A no-frills and easy to use approach

Reasons to avoid

-
Calibrated for 440Hz concert pitch only 

Fender took a different aesthetic approach than the competition here – though there's still a sturdy clip to keep this Bullet firmly on your headstock. We really like the low key look here that still manages to keep the note and reading on the circular colour display clear.

The one cent accuracy will be good enough for most of us and the response is sensitive and fast, but the option of only 440Hz calibration might be an issue for some players – especially if you play in an orchestra. On the whole though, this is another winner from the big F.

Not for electric players – unsurprisingly! 

Something different here – and specifically for acoustic guitar players as this NS Micro series tuner fits on the rim of your soundhole, placing the tuner inside the body but still readable. It's so out of the way you can just leave it fitted on your guitar permanently.

It works really well and the accuracy for the price here is even better news – to 0.3 cents with calibration between 434 and 445Hz.  There's no reason you can't fit it on other stringed acoustic instruments (though D'Addario offer the PW-CT-NS specifically for ukulele players) .

 On the more expensive side

Korg is a master of technology within the music industry. From synths to studio gear, to guitar pedals and now to this – its Sledgehammer Pro clip-on tuner – Korg knows how to make a quality and reliable product. The curved screen means you don’t need it straight on to be able to read; handy if it gets knocked while you’re playing or tuning. The display is reminiscent of its rackmount studio tuner, so instantly it’s got a premium feel about it. It’s also accurate, which is the all important thing, measuring your tuning to .1 cent. 

We also really like the shuttle switch on the hand – it’s really easy to operate and feels a little less awkward than having to reach around to the back or bottom of the tuner to access different modes etc, like you do on some other tuners.

Doesn’t look as premium as it could 

Another entry courtesy of Boss. It's the maker of the world’s best selling tuner pedal, so it knows what it's doing! As well as good accuracy, the Boss TU-10 offers a slightly different design. This one has a fairly low physical profile, so when it’s clipped onto your headstock, there’s not too much plastic sticking out the top.

It features Boss’s Accu-pitch, which essentially just helps you determine whether you’re sharp or flat, though you can choose to use Stream mode which allows you to tune using a strobe. It can also cater for flat tunings, up to five semitones. It’s really practical, and thought has gone into this clip-on tuner - even on the brightest days, the small screen manages to not reflect too much light, making it really easy to read.

Best clip-on guitar tuners: Buying advice

What are the types of clip-on tuner?

There are a few different types of clip-on tuner too, so when you see these phrases being used, you’ll know what they mean.

A chromatic tuner means that it will detect any note being played. In western music, there are 12 notes; of course for all of these you can be either sharp (higher in pitch), or flat (lower in pitch), but a chromatic tuner will tell you which note you’re closest to and how far off you are.

Polyphonic tuners can detect more than one string at once. As technology has improved, manufacturers have been able to make tuners that can track multiple strings being played at once more accurately. Now, some of the best clip-on tuners out there can show you where all six of your guitar strings are tuning-wise, so it’s easy to detect which, if any, need adjusting.

Strobe tuners refer to the way in which the display will read the note back to you. Lights on the tuner’s screen will move quickly when your string is out of tune and gradually get slower as you approach the note. These tend to be very reactive to your tuning pegs, so small adjustments will make all the difference here. They’re very accurate and allow for super precise tuning.  

Are clip-on tuners more accurate?

In a perfectly quiet environment with no extraneous noise, a clip-on tuner can be incredibly accurate. Compared to a phone app or a tuner that uses a microphone, clip-on tuners are far more effective than these. That said, a clip-on tuner won’t be as effective as a guitar tuner pedal, as they will still be susceptible to certain loud noises, like when your bassist really cranks their amp for example.

For guitarists playing at home, or those who perhaps only do acoustic or solo gigs, however, a clip-on tuner is perfect for these types of situations. We’ve seen a lot of guitarists use clip-on tuners at gigs as well, although in some cases you may have to ask your bassist or drummer to be mindful when you’re tuning up!

Are clip-on tuners good for bass?

Yes, a good clip-on tuner will work fine on bass guitar. Cheaper models may struggle to detect the low vibrations of a bass but if you buy a good quality one then you shouldn’t have any issues. As with any kind of clip-on tuner, extraneous noise can cause issues, but plenty of clip-on tuners have dedicated modes for tuning bass guitars.
