PolyTune 3 Power — All in a Mini Pedal Format

The PolyTune 3 Mini manages to pack all the pedal-tuning and tone-preserving power of TC's full-sized PolyTune 3 into a miniature pedal format. The TC Electronic PolyTune 3 Mini is just as fast, dependable, and intuitive as ever, boasting accuracy within 0.02 cents and delivering a no-nonsense approach to guitar and instrument tuning. Strum all strings* to see which ones are out of tune at a glance, or tune up one string at a time. The PolyTune 3 Mini automatically switches between mono and poly modes based on the incoming signal. And thanks to its built-in, high-quality-analog BonaFide Buffer (switchable to true bypass), the PolyTune 3 Mini can even improve your tone over extended cable runs. This means you get a bite, presence, and transient response that's much closer to plugging directly into an amp. But that's not all that's cool about the TC PolyTune 3 Mini. 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, 109-LED display makes tuning more comfortable in any environment, indoors or out.

*Polyphonic tuning mode is accurate to within 1 cent.

BonaFide Buffer is an added value built right in

TC managed to cram its award-winning BonaFide Buffer circuitry into the PolyTune 3 Mini's pedalboard-friendly 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 Mini at the front of your board — its preferred position — your tone is as good as unfazed for another 50 feet or so 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 Mini is well worth the upgrade.

Picky about your signal path? PolyTune 3 Mini 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 Mini. 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.

Tune all your strings at once

The TC Electronic PolyTune 3 Mini 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 Mini 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.

*Still prefer traditional tuning? The TC PolyTune 3 Mini switches between mono and poly modes automatically.

Choose strobe mode for up to ±0.02-cent accuracy

Do you know how precise 0.02 cents is? It's 1/5,000th of a semitone — 1/5,000th the difference between an open E and a fretted F. The PolyTune 3 Mini 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? The PolyTune 3 Mini's lightning-fast chromatic mode still gives you accuracy within half a cent.

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

Brighter, and more dynamic than ever, PolyTune 3 Mini'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 Mini dims its display on dark stage floors so you don't scorch your retinas every time you look down at your board. This is just another way the PolyTune 3 Mini brings TC Electronic's spirit of innovation to your guitar rig.

Reviews

Super simple tuner with big bright display
I've had a Boss Chromatic tuner for the last few decades and it's still working fine, however, it's gotten harder and harder to see it from standing esp. in dim stage lighting and it can't be turned on/off or tune quietly.
This is where the polytune shines: it's simple, bright and clear. It lets you know when you are spot on or a shade under/over it can be set to kill the signal to the amp when on for silent tuning and comes on and off with a foot switch. It takes probably the bare minimum of space on a pedal board (it's only about as wide as a standard 1/4 inch jack The only thing I can say critical is the lack of weight makes it more prone to move about if not not tacked down with velcro or such.
Polytune Mini
The most accurate needle tuner I've ever had. I read that the strobe tuner is even more accurate. I use it with my acoustic guitar rig so I can also use the Polytune function. A really fast way to double check the tuning. It's not as accurate the needle or strobe function but it's a quick way to look at the tuning after a tune up.

The Best
The best tuner ever, I liked so much and I completely advise everyone to have this on the pedalboard.
Poly tune Mini 3 and Sweetwater service
I needed a small tuner for my small pedal board and this seemed to fit the bill. Excellent product that was recommended by a friend. I used it at a gig last weekend and worked flawlessly. The "quiet" tuning feature is also a great way to change guitars without any noise. Highly recommended.

The first one that was sent was DOA. I was disappointed and called Sweetwater. I got a replacement the next day! And they paid the postage for me to send the broken unit back to them. THIS is why I always buy from Sweetwater. Many vendors offer the same prices but the service Sweetwater is top notch. And I love th goodie bags! Thanks you guys for working so well with your customers.

User friendly and ultrafunctional tuner pedal
I previously heard about this product several years ago. At the time, I did not need a tuner pedal. My electro-acoustic guitar has an integrated tuner and I used to have an all-in-one guitar pedal that had its own tuner. When I started to build my pedalboard, I decided to add this particularly tuner pedal to my board. It takes a very small amount of real estate. The tuner allows you to tune one string at a time or check the tuning of all strings at once. The tuner is very precise. I decided to buy this tuner pedal over others because it is possible to quietly and quickly check tuning during a gig or even at home. I have the tuner pedal as the first in my chain. I definitely recommend this pedal.
