Positively PolyTune

Tuning used to be a necessary evil. The last barrier before you could get truly rocking. But now, tuning is ready to get blasted into the 21st century with PolyTune, the stomp-box sized tuning miracle from TC Electronic!


  • PolyTune Technology - Tune All Strings Simultaneously
  • Drop-D, flat tunings and capo-ed tunings
  • Awesome chromatic tuner included

Polyphonic Tuning Couldn’t Be Done - Until We Did It

With PolyTune, you simply strum all strings on your guitar or bass at once, and it will immediately tell you which strings need tuning! It really is as simple as strum - tune - rock, and this quantum leap forward allows you to get in tune fast, and back to doing what you love: playing!

Tuning Modes

With modes ranging from Drop D, 5 semitones flat and capo tuning on frets 1-7 gives you the freedom to do what you want creatively and know PolyTune has your back.

Old Skool - Still Cool

You want a chromatic tuner? You got it! PolyTune features MonoPoly a technology that allows PolyTune to detect whether you play one or multiple strings and react lightning by changing to chromatic mode if that's what you need. Our chromatic tuner is second to none when it comes to accuracy and speed.

Backstage Pass - All Access

PolyTune's features are supercool and squarely aimed at getting in into tune and back to rocking ASAP.

Tuning Magnet

The tuner magnet feature slows down the needle once you get close to the desired pitch, making it much easier to get the job done quickly.


MonoPoly is a jaw-dropping new technology that recognizes whether you play one or more strings and instantly replies with the appropriate poly- or monophonic tuning mode.

Total Recall

PolyTune stores your preferences. From pitch reference to tuning mode, it hangs on to this information even after it is powered down, making sure you only have to set how you want things to happen once.

What is the Matrix?

PolyTune features 17 rows of LEDS which allow for a higher resolution and the LEDs themselves are super bright and focused to ensure optimal visibility at all times.

True Bypass

This allows for your carefully sculpted tone to flow unaffected when the pedal is bypassed and for silent tuning once engaged.

Chromatic Champ

Besides the Polyphonic tuner, PolyTune has a chromatic tuner that can hang with the best current tuning technology out there, with an amazing 0.5 cent accuracy.

PolyTune: Strum – Tune – Rock!

PolyTune® is the world’s first polyphonic tuner – a multiple patents pending, game-changing total tuning turnaround that allows you to instantly gauge the tuning of all your strings simultaneously and tune up on the fly, ALL strings at once. What else can we say besides: BAM, son!

The PolyTune is an essential lifesaver for time-pressed gigging guitarists and perfectionist studio players. It shaves precious seconds off the tuning process while it provides dead-accurate tuning.

The PolyTune is innovative, fast, accurate, and versatile, and as it’s the only polyphonic tuner you’re going to get for $99, how could it not snag an Editors’ Pick Award?

My tuner has always been the one thing I’ve hardly ever thought about changing. Now that I think about it, I’m pretty sure I’ve traded it out only two or three times—which is nothing compared to the countless delays and overdrives I’ve gone through over the years. Does the PolyTune qualify to be a rare entry in that list of tuners? Most definitely.

Were it a straight automatic chromatic tuner it would be good, but by adding the polyphonic mode for an instant view of all six strings, it becomes an undoubted winner at a very reasonable price. Highly recommended. Verdict: A significant stomp forward, destined for pedalboards everywhere!

I have to conclude that this sturdily built little tuner does pretty much what it claims to, with no fuss and with a nice clear display. Its compact format makes it easy to fit into a pedalboard, and its true bypass means that it won’t compromise your tone.

The TC Electronic Polytune is an exciting new pedal that is set to revolutionize the way guitarists tune their instruments.

by Red Led

TC Electronic incredibly managed to launch a totally new product in the tuner pedal market, which is quite a feat. The manufacturing quality is impeccable and the product is packed with clever ideas like the auto adjustment of LED intensity, the power output and the dual needle/caterpillar display in monophonic mode. One thing is for sure: all competitors suddenly look a lot older and the PolyTune offers much more for the same price.

The ability to check all strings simultaneously is nothing short of revolutionary. With the groundbreaking, time-saving, and (dare I say) performance enhancing convenience of polyphonic tuning thrown in the mix, there's simply no competition.

Its rugged metal housing and the perfectly lit and easy to read display make it the ideal partner on the stage as well as in the studio. The TC Polytune is currently one of the best tuners on the market, with all its features it's worth every penny.

I felt so cool when I would hit the tuner, unplug one guitar, plug in the next guitar, give it one strum while muted, make a few adjustments and move on to the next song. There were much fewer awkward pauses between each song where you feel like you have to stall while your dumb guitar gets tuned.

The polytune is a transparent addition to your pedalboard. The true bypass circuitry works as expected, and our signal sounded the same bypassing the tuner as it did with a cable straight into the front of our amp.

The auto switching feature is great so you can decide for yourself. If you’re a cutting edge Poly Tuner – go for it! If you’re old school, go string by string – doesn’t matter. The PolyTune will get you there quickly and reliably one way or another.
