TC pushes the envelope yet again for what's possible in a tuner pedal! The TC Electronic PolyTune 3 is faster, more dependable, and more intuitive than ever, boasting accuracy within 0.02 cents and a no-nonsense approach to guitar and instrument tuning — strum all strings* to see which are out of tune at a glance, or tune up one string at a time. Thanks to its built-in BonaFide Buffer circuitry (switchable to true bypass), PolyTune 3 can now even improve your tone for long cable runs. This means you get the treble and transient response that's much closer to plugging directly into an amp. But that's not all that's improved in the TC PolyTune 3. Alternate tuning modes make it fast and easy to explore new ways to craft your art, even in the middle of a frantic set. And an improved auto-dimming LED display makes tuning more comfortable in any environment, indoors or out.

What's new in the PolyTune 3?

BonaFide Buffer is added value built right in

TC managed to cram its award-winning Bona Fide Buffer circuitry into the PolyTune 3's compact housing. So now, the latest iteration of this beloved pedal actually improves your tone over long cable runs. Whereas true bypass pedals can start to rob the treble end of your signal, by placing the TC Electronic Polytune 3 at the front of your board — its preferred position — your tone is as good as unfazed for another 50' of cable. Past PolyTunes have been hard to beat. But take it from Sweetwater — thanks to its built-in BonaFide analog buffer, the PolyTune 3 is worth the upgrade.
Persnickety about your signal path? PolyTune 3 also includes a switchable true bypass option.

Alternate tuning modes to stoke your creativity

Alternate tunings are another performance-enhancing feature of the PolyTune 3. Now you can show off your open-tuned slide songs seamlessly in the middle of a set, or experiment with brilliant new acoustic voicings as you track in the studio.

Faster and more intuitive than ever

Tune all your strings at once

The TC Electronic PolyTune 3 spares your listeners the "E, A, D, G..." pre-show tuning ritual with its polyphonic tuning mode*. Here you can strum all strings at once, and PolyTune 3 shows you at a glance which strings are out and which ones are okay. Attacking only the pitchy strings saves time tuning up and keeps shows running smoothly without interruptions.
Do you still prefer traditional tuning? The TC PolyTune 3 switches between mono and poly modes automatically as you begin tuning up.

Choose strobe mode for up to 0.02-cent accuracy

Do you know how precise 0.02 cents is? It's 2/10,000th of a semitone — 2/10,000th the difference between an open E and a fretted F. PolyTune 3 delivers the kind of accuracy you need to double-track guitars in the studio or tune fretless instruments to the rest of your arrangement.
Need speed over accuracy? PolyTune 3's lightning-fast chromatic mode still gives you accuracy within half a cent.

Auto-sensing LED display is easy to read on any stage

Bigger, brighter, and more reactive than ever before, PolyTune 3's dazzling LED display makes tuning up in any environment a breeze. This flexible display is made up of over 100 ultra-bright LEDs that provide clear visibility even in broad daylight. And thanks to the onboard ambient light sensor, the PolyTune 3 dims its display on dark stage floors so you don't scorch your retinas every time you look down at your pedalboard. This is just another way the PolyTune 3 brings TC Electronic's spirit of innovation to your guitar rig.
