High-precision polyphonic clip-on tuner for stringed instruments

The TC Electronic PolyTune Clip Black tuner combines cutting-edge tuning technology with outstanding aesthetics and functionality, which makes it the perfect tool for musicians who wish to make no compromises in terms of speed or precision when tuning their instrument. The PolyTune Clip has been designed to be a reliable partner for guitarists and bassists in any situation – whether they are quickly checking their tuning on stage or making sure everything is perfectly in tune before a recording – and offers three different tuning modes: Polyphonic tuning, which allows all strings to be tuned at once, conventional chromatic tuning, and high-precision “strobe” tuning, which offers an impressive accuracy level of ±0.02 cent.

Polyphonic and chromatic tuning with high precision

Basic electronic guitar tuners only allow the open strings to be tuned individually to standard tuning (E, A, D, G, B, and E), which is a time-consuming affair. The PolyTune Clip, on the other hand, is a chromatic tuner, which means it recognises each note and allows each string to be tuned accordingly. And that is not all: Unlike conventional tuners, the PolyTune Clip also allows all of the strings to be struck at the same time while tuning. Its highly responsive piezo sensor then rapidly analyses the pitch of each string, and the display indicates which strings need to be adjusted. The tuning process is thus made significantly faster than using conventional methods.

Discreet and perfect for continuous use

Whether you are a beginner tuning your guitar or bass every day or a professional musician who likes experimenting with alternative tunings, the PolyTune Clip will keep your instrument precisely in tune thanks to its high-speed tracking and its unique polyphonic tuning function. Despite its extremely compact dimensions, the tuner’s bright swivel-mounted LED display ensures a clear overview at all times, even in the darkest corner of the rehearsal room. Thanks to its robust stainless-steel clip, the tuner – which weighs just 32 grams – will always stay firmly seated on the instrument’s headstock and secured against accidental slippage.

About TC Electronic

The Danish company TC Electronic has been known for its innovative products for many years. It was founded in 1976 by brothers Kim and John Rishøj in Aarhus. The company first made a name for itself with the SCF, a stereo chorus/flanger pedal for guitar. Studio equipment followed during the 80s and 90s, notably the legendary TC2290 digital delay in 19-inch rack format. Since the 2000s, TC Electronic has greatly enriched the guitar and bass scene with amplifiers, cabinets, combos, and effects pedals. Here too, TC's innovative spirit is in evidence, for example with its TonePrint technology and the first polyphonic guitar tuner. TC Electronic has been part of Music Tribe since 2015.

Your loyal day-to-day companion

Thanks to its light weight and swivel-mounted display, the PolyTune Clip can be attached discreetly to the headstock of virtually any stringed instrument – whether it’s an electric guitar, an acoustic instrument, a bass guitar, or even a ukulele. Its polyphonic tuning function together with its bright and easy-to-read LED display mean precise tuning takes no time at all, which is particularly valuable during live performances. What is more, musicians who regularly play in alternative tunings can always rely on the PolyTune Clip whenever they choose to venture beyond the scope of regular “standard” tuning.

The *only* tuner you need (probably)
Rad Dad 04.05.2017
Let's make this quite clear right at the start. This tuner is AWESOME.
Tuning really has been the bane of my life for 30 years. I'd get a string tuned - go on to the next one - all the way through the six. Every one, as I thought, 'spot on'. I'd play a chord - it just sounded so wrong! So - start again. I'd spend more time tuning than playing. And intonation?! Just don't start me on that.
Well - in one of the Harley Benton Facebook Support Groups, a chap gave a little review. Said this wee gadget was the best thing that ever happened to him. Said it 'did' intonation. I was intrigued. How could this be? It was a bit expensive - as I was used to paying less than 10 Euros for a simple clip-on tuner - but I headed on over to TC's website and had a look at the specs.
I thought I'd give it a go - Thomann's guarantee meant I could always send it back, no questions asked, if it was no good for me.
Weeeellllll. I took it out of its smart little box and pressed the small switch. Oo! It burst into life with a rather fetching moving line of green lights. "Ey up", I thought to myself "this could be good".
I clipped it on my guitar and played a note. Lights moved back and forth. A letter appeared. It was only the darn note I was playing! As I tuned the string, lights continued to move - red and green ones. Vertically and horizontally. Until...when it was spot in tune, there were just two bars of vertical green lights and a horizontal bar of green lights either side. Slightly off - even just the slightest turn of a machine head - and some red lights would appear *to one side of the bars*, showing if the note was now sharp or flat. Wow. Easy tuning...
I played another note - it again gave me the name of the note. I played an octave, to check for intonation of the E I had just tuned. Again - it gave me the name. Ever so slight red lights accompanying the green - indicating intonation would need a slight tweak. But I couldn't tell - it sounded great to me!
And wait for it.....if you play a will tell you the name of the chord (as long as it isn't too complicated). And - in this case, you get a couple of bars for Each. Of. The. Six. Strings. String in tune - green lights. Slightly out - red lights above or below the green. All six strings at once.
I really can't recommend this tuner enough. No more tuning woes. A permanent fixture, it is. Best 49 Euros I've ever spent on guitar related stuff. Who'd have thought it?
And when you're not using it - it just sits there, black as anything, like the stealthy tuning ninja it is.
Buy one you must.


The best!

Tried a few other headstock tuners over the years, always come back to the polytune for its high sensitivity and strobe function.


Not as accurate as i would have liked
Anatoly 22.03.2019
It's a tuner. It's well-made, clearly legible and overall feels like it can survive quite a bit of abuse. There are enough features to make it work in every situation, and as a bonus, you also get a free plugin version of this same tuner (which is why i picked it up in the first place).

One thing i should mention though is that the accuracy of polyphonic mode is only adequate at best. Tuning up with polyphonic mode is really not going to do you any good.

Here's how it usually goes. Option 1:

1) strum my strings
2) oh, strings X and Y are out of tune
3) tune them up in polyphonic mode - cool, everything is green now!
4) check each individual string - oops, they're actually out of tune now!

Option 2:

1) strum my strings
2) oh, strings X and Y are out of tune
3) tune them up individually - cool, they're all tuned up now!
4) strum my strings - polyphonic mode still says they're out of tune
5) check them individually - they're in tune. WTF?
6) go to 3)

The reason this happens is because the single string tuner is not precise enough (disclaimer: i haven't yet tried strobe mode, maybe that would be more accurate), so when you tune up your strings individually, if you use a more precise tuner you'd see that you're actually off by 2-3 cents. These miniscule tuning differences are enough to throw the polyphonic tuner off. If you actually tune yourself up with a different, more precise tuner, you'll find that both single-string and polyphonic tuner now agree.

In other words, the polyphonic tuner requires *extreme* tuning accuracy before it can show that the guitar is in tune. However, as was demonstrated above, it is possible to make polyphonic tuner show that everything is in tune while still having individual strings out of tune, rendering this polyphonic display essentially useless because you cannot trust it. It's pity that, when it comes down to it, this functionality is little more than a gimmick. I mean, it's not *totally* useless, but if at the end of the day you still find yourself reaching for individual string tuner, you might as well just get the Unitune, which is cheaper. Unless you want the tuner plugin :)


Good - But
Nonameguy 30.06.2021
It is an excellent Tuner, provide strobe and needle options as well as Polyphonic for Guitar only and Chromatic modes.

It switches off automatically after 5 mins even if you are tuning with at the time, which can be annoying.

Clip could do with a bit more rubber padding, as part of the metal on the clip are bear and potential could scratch the head of you guitar.

Tuner should be able rotate on clip, but it doesn't so to get it pointing in the right direction can take a bit of repositioning and reclaiming at times.

Works for Bass but only offer Poly mode for Guitar, does not give option for other stringed instruments.
