Product Description

Polytune is a brand new pedal from TC Electronic that utilizes patented polychromatic tuning technology to show guitar and bass players an entirely new way to tune their instruments. With the addition of strobe and needle modes, players will enjoy extremely accurate tuning as well as a true bypass circuit. Let the Tuninig commence!

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 PolyTuneTM, the stomp-box sized tuning miracle from TC Electronic!

PolyTuneTM is the world's first polyphonic tuner, and a game-changing total tuning turnaround that will have future guitarists wondering how we ever got by without it.

It couldn't be done - until we did it
The magic lies in a never before seen approach to tuning aimed at speed, accuracy and ease of use. With PolyTuneTM, you simply strum all strings on your guitar or bass at once, and it will immediately tell you which strings need tuning! This cutting-edge tuning technology revolutionizes the way you tune and accomplishes what has been deemed 'impossible' until now: tuning all strings simultaneously! 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.

Strum - Tune - Rock
Providing an instant overview of the pitch of all your strings, PolyTuneTM is an invaluable tool in live-settings, where it is essential to be in tune quickly and ready to play. Crowds don't want to wait around, they want to rock, and, let's face it, so do you. Besides live use, this stomp box will deliver like no other in any situation where you want to get tuning out of the way and focus on play.

Fever Pitch
Equally effective for guitar and bass, PolyTuneTM is extremely flexible as well. The reference pitch can be set to your preference and ranges from 435Hz to 445Hz. This guarantees you'll be able to play along with anyone, with any instrument and in any situation.

Drop it like it's hot
If you are a guitarist that likes to play at a different pitch than standard, this is your go-to pedal, allowing for dropped tunings from E-flat all the way down to B. Whatever your pitch or tuning, PolyTuneTM is a sure-fire way to be spot-on, with an accuracy of just plus/minus 1cent.

Chromatic champion
Besides the Polyphonic tuner, PolyTuneTM has a chromatic tuner that can hang with the best current tuning technology out there, with an amazing 0.5 cent accuracy. But we are never satisfied with the current norm, and added some features to make this tuner's chromatic section stand out from the crowd.

Tuning modes
Let's start with the two separate chromatic tuning modes, which cater to your individual preferences and needs. Needle mode is for those that are used to the classic view on a tuner. For the people that want a little more real-time information, we have included stream-mode, which measures even the slightest pitch variation and instantly feeds the info back to you via a rotating motion on the display.

Tuning Magnet
Key to both these great chromatic modes is an ultra-fast and precise response, which is achieved via the use of the unique tuner magnet feature. This slows down the needle once you get close to the desired pitch, making it much easier to get the job done quickly.

Whether you want to use the polyphonic tuner to get in tune, or prefer to go the chromatic route,this pedal has you covered. PolyTuneTM features "MonoPoly", a unique patent-pending technology that recognizes whether you play one or more strings and instantly replies with the appropriate poly- or monophonic tuning mode.

Total Recall
Of course, all of these amazing features would not mean a thing if they were a pain to use or set up. So, we added some traits to ensure this tuner is calibrated to the guitarist. Unlike most other tuners, PolyTuneTM 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.

The next time you power up again, it will show you the settings, so you instantly know Everything is exactly how you want it to be.

Tuning as it should be
PolyTuneTM was our chance to build the ultimate tuning tool from the ground up and finally get rid of some of the current tuner drawbacks that guitarists run into time and time again. Tuners have been around for some 30 odd years and we felt it was high time they got in tune with todays guitarists.

Design is where beauty and technology meet
But besides all the spearheading features inside the tuner, we took a long hard look at the outside as well, and pushed tuner design to new heights in the process!

A strong display of innovation
Starting with the display, it instantly becomes clear why PolyTuneTM is lightyears ahead of current tuners. Guitarists that play gigs, will no doubt recognize the nightmare of an unclear display, due to for example bright sunlight, an overeager light technician or a stage smoke machine gone bonkers.

What is the Matrix?
PolyTuneTM features 17 LEDS which allow for a higher resolution and the LEDs themselves are super bright and focused to ensure optimal visibility at all times. This guarantees the most effortless tuning experience money can buy. And as an added bonus, the 100 LED matrix can give you information right on the display, so you won't have to go dig for the manual mid-gig.

Size Matters
PolyTuneTM will brighten any pedalboard, and we aren't just talking about the LEDs! Besides looking like a million bucks, its small footprint design means that PolyTuneTM doesn't take up more of your precious pedalboard real estate than absolutely necessary.

Spruce the juice
Battery changes are a breeze thanks to the one-screw easy access to the battery compartment and when powered by an external 9v DC power supply, the 9v DC out can be used to power other pedals on your board.

True Bypass
The true bypass feature ensures PolyTuneTM is only there when you need it. It allows for your carefully sculpted tone to flow unaffected when the pedal is bypassed and for silent tuning once engaged.

We can't make tuning fun. But we can sure make it a whole lot easier.
We want to do our part for the guitar community and truly innovate the life of guitarists. And with PolyTuneTM's extraordinary features and cutting-edge technology, we feel we have accomplished just that. We are passionate guitarists ourselves and we work every single day to make all our lives easier and more rocking.

I've used quite a few stage tuners over the years, most recently a pair of Boss TU-2's, excellent tuners in their own right. This tuner beats the Boss units. It offers an incredibly useful but unique feature. Strum your guitar with the strings open and you'll instantly see a curved row of six paired-green dots (plenty bright and easy to see). Any string out of tune will display a pair of red dots immediately below the green ones, thus indicating which if any strings are out of tune. Go to an out-of-tune string and the display immediately changes to an LED-simulated needle display typical of an analog tuner. Tracking is very fast and very accurate. Tuning between songs is a breeze with this thing since you don't have to check each string one at a time; just strum and then tune the strings that need it. When I first got it I did the strum and tune thing and then tested each string with my Peterson VSAM Strobe Tuner as a check - all were spot-on. Add to the speed and accuracy the fact that this is built like a tank and features true bypass, and you've got the best stage tuner available. And with all that, the price is roughly the same as any other good stage tuner. This is one of the best guitar devices out there.

I bought this pedal about a month ago when I started putting together a new pedal board. Initially, I was pleased with its operation, size, design, and construction. The normal tuning modes were accurate, however, the "string strumming" function was not very useful to me. It's good for getting a quick "rough estimate" of whether you're in tune or not, but it's not very accurate. My main issue with this tuner is that it KILLS YOUR TONE! When I completed my pedal board, I noticed that something didn't sound right, so I checked the signal through each pedal and traced the problem to the Polytune. I would never have thought that a "true bypass" tuner would be a suspect for killing signal, but I determined with my DMM that the Polytune was cutting my 6.90K ohm guitar output signal to around 3.6K in "true bypass" mode. Basically, it made my guitar sound like I rolled off 1/3 of the volume. Not good! I don't know if it was a defective pedal or if they are all that way, but I have read a few complaints from people that have noticed a similar problem. I just returned the Polytune and ordered the Boss TU-3. I know this is not true bypass either, but given Boss' track record, I doubt I will have problems with such severe signal loss.

Compared this to my Korg blackout and did a meter reading via Allen and Heath Mixer and computer. Absolutely the same frequency and sound levels. Did a comparison without any tuner, strait in, no difference. Of course, I do have some pedals going after the tuner, with one that is not true bypass. Don't be fooled, if you are having troubles with sound loss with this pedal, you are getting the same sound loss with other pedals, or you have a bad cable, or even more common, bad power supply. But, if you have one out of 8 of your pedals without true bypass, just one with a buffer, you'll be good.

Tuning - I was VERY skeptical. But, it works. Completely detuned my guitar, strummed, had it back in tune in lesson than 15 seconds. And it was VERY out of tune. Clear to read, looks great on the board, and firmware can be upgraded as the technology gets better.

Highly reccomend. Professional musician with over 700 gigs of experience and I've been playing for 25 years. It works.

This is an awesome tuner. The screen is very bright and easy to read, even when I don't have my glasses on. Can't stress enough just how nice the screen looks. It's got a 9V out on it, so if you need to chain another pedal through this one, the option is there. The pedal works in Strobe mode as well as standard (needle-style) chromatic mode. It's very quick and very accurate. It did get a little befuddled at first... I think it thought I had a guitar, but I play bass... but it's adjusted and it will always remember your settings even if left unplugged.

It was just about the same price as the Boss TU-3, which is the 'new' standard pedal tuner... I chose this one for the bright screen, and true bypass. I didn't expect the Polyphonic tuner to work as accurately as it does, but you can definitely strum and get all your strings 100% in tune, and then even check string by string if you want to have the monophonic screen come up.

If you're looking for a rock-solid pedal tuner, this is an excellent choice.

I'm on my second one and returning it. Neither one has been "true bypass", both had huge signal loss. Not a cord issue, not an effects chain issue...tried direct in and out to amp with several cords, guitars, and amps. Same result. Upside, it is beautifully finished and tunes well with a great display, but in my opinion probably released to early and poor QC. Too bad, I was excited about it, but certainly can't use it.

I like this tuner a LOT. Aside from the polyphonic mode, this is a better stomp tuner than any I've used under $300. Nice and bright and MUCH faster at registering notes than the Boss and Korg.

I think of the poly as an extra feature. Between songs for a quick check, it's perfect for fine tuning. But pull your guitar out of the case and more than a couple of strings are out, I find that it isn't super-accurate. Again, I would give this 5 stars even if it didn't even have the poly mode, so I didn't count against it for that.

Great tuner
