As the world’s first polyphonic tuner, the original POLYTUNE took the hearts of guitarists by storm. Features such as the MonoPoly technology (which automatically detects whether you want to tune a single string or all strings) made tuning a bass or guitar faster and easier than ever before.
So how do you make the best-selling polyphonic tuner even better? You take it to the next level by: providing multiple tuning modes, including polyphonic, chromatic, strobe and a variety of altered tunings; adding an onboard BONAFIDE BUFFER to preserve your tone over long cable runs and pedal board signal paths; and upgrading the LED display for even higher tuning accuracy.
Enter POLYTUNE 3.
Your TC ELECTRONIC effect pedal box should contain the following items:
- Your TC ELECTRONIC effect pedal
- 1 TC ELECTRONIC sticker
- 1 Quick Start Guide for quick information about the pedal’s controls
Inspect all items for signs of transit damage. In the unlikely event of transit damage, inform the carrier and supplier.
If damage has occurred, keep all packaging, as it can be used as evidence of excessive handling force.
Connect a 9 V power supply with the following symbol to the DC input socket of your TC ELECTRONIC effect pedal.
This product does not come with a power supply. We recommend using TC ELECTRONIC’s PowerPlug 9 (sold separately).
- You can also power POLYTUNE 3 using a standard 9V battery (not included), but if you intend to power additional pedals using the power out jack, you need to use a power supply. Plug the power supply into a power outlet.
- Plug the power supply into a power outlet.
- Connect your instrument to the in jack on the right side of the pedal using a 1⁄4″ jack cable.
- Connect the out jack on the left side of the pedal to your amplifier using a 1⁄4″ jack cable.
- If you have another 9 V guitar pedal that you want to power, connect it to the power out socket on the rear of the pedal.
Get ready for a new tuning experience!
Tuning your instrument with POLYTUNE 3 is fast and intuitive. If you don’t feel like reading the manual, just strum your instrument and watch the display. We think you’ll like what you see.
If you want to learn more – read on!
Here at TC ELECTRONIC, we have a simple philosophy: When you are using one of our products, you should hear something great – and if you don’t, you shouldn’t hear it at all. This is why this pedal sports True Bypass. When it is bypassed, it is really off and has zero influence on your tone, resulting in optimum clarity and zero loss of high end.
POLYTUNE 3 lets you switch between True Bypass and Buffered Bypass modes, the latter giving you an “always on” option that keeps the tuner in full operation – even when your signal is not muted. Tuning made simple and more efficient than ever.
Sometimes, it is advisable to switch an effect pedal from True Bypass to Buffered Bypass mode. For more information, see “6.2 Switching between True Bypass to Buffered Bypass”.
Brighter than a thousand suns
When you need to tune, you need to tune. And the last thing you want to worry about at that moment is a display that is either too bright for the club stage or unusable in the bright sun of a late afternoon gig. The display on POLYTUNE 3 is primed with some of the brightest LEDs you have ever laid your eyes on. And the ambient light sensor makes sure you get just the right amount of brightness. It’s the best of/for both worlds!
TC has received many requests from the guitar community for a strobe tuner, so we added a strobe mode, which is both lightning fast and ultra precise. And with a pitch detection accuracy of ±0.1 Cent, (that’s 1/1000 of a semitone!) this is the right tool for fi ne-tuning your precious instrument – wherever you may be.
POLYTUNE 3 stores your preferences. From pitch reference to selected tuning mode, it hangs on to this information even after it is powered down – making sure you only have to set these parameters once. And just to be safe, it will display the current settings when you plug in your instrument. One less thing to worry about!
Of course, POLYTUNE 3 still has all the features from the original POLYTUNE that users know and love.
- POLYTUNE®: Tune all strings simultaneously
- For guitars and basses
- Supports Drop-D and capo tuning modes
- True bypass with silent tuning
- Buffered bypass to compensate for long cable runs
- DC output for powering other pedals
POLYTUNE 3 will allow you to tune your instrument faster and easier than ever before, so you can go back to doing the one thing we know you care about: playing your music.
Operation – Inputs, Outputs and Controls
- POWER input To power up your pedal, connect a power supply to its power input socket. POLYTUNE 3 requires a 9V power supply providing 100 mA or more (not supplied). To minimize hum, use a power supply with
The power input of this pedal is a standard 5.5/2.1 mm DC plug (centre = negative).
- POWER output If you use are using an external power supply to power POLYTUNE 3, you can use the power out jack of POLYTUNE 3 to provide power to other, daisy-chained guitar pedals.
- Make sure that your power supply delivers sufficient power to cover the power consumption of all connected pedals.
- Current draw on pedals daisy-chained to the power out jack may not exceed 2A.
- TUNING MODE button Set the tuning mode button according to the instrument’s tuning. Use either standard (“e”) or one of the several dropped tuning or capo modes.
Tuning modes are explained in the following section of this manual (“How to use POLYTUNE 3”).
The selected tuning mode is stored and will be recalled when you power on POLYTUNE 3 again.
- USB port If there should be firmware updates for this pedal, they can be installed by connecting it to your computer using this port.
- DISPLAY MODE button Use the display mode button to switch between the various display modes.
The various display modes are explained in the following section of this manual (“How to use POLYTUNE 3”).
The selected display mode is stored and will be recalled when you power on POLYTUNE 3 again.
- DISPLAY The LEDs of the POLYTUNE 3 display are extremely bright; ensuring a clear readout even in broad daylight.
The various display modes are explained in the following section of this manual (“How to use POLYTUNE 3”).
- AMBILIGHT sensor In the lower right corner of the display is an ambient light sensor that detects the strength of the surrounding light and automatically adjusts the display brightness accordingly. This ensures you can see and correct your instrument’s tuning under all conditions. This feature even extends battery life by reducing display brightness to what is required in a given situation.
- AUDIO INPUT Connect your instrument to the IN jack on the right side of the pedal.
The audio input of this pedal is a standard 1⁄4″ jack (mono/TS).
When you connect your instrument to the audio input, the following information will be displayed:
• Standard (“STD”) or Drop D tuning mode
• the currently selected display mode (Needle / Strobe, Guitar / Bass)
• the currently selected tuning mode
• the reference pitch.
For best results, place POLYTUNE 3 in your signal chain before your drive, distortion and vibrato pedals. A distorted or modulated signal is harder to analyze.
If the pedal runs on battery power, we recommend removing your instrument from the audio input to preserve battery power when you don’t play.
- AUDIO OUTPUT Connect the OUT jack of POLYTUNE 3 to the input jack of the next device in the signal chain.
The audio output of this pedal is a standard 1⁄4″ jack (mono/TS).
- FOOTSWITCH To turn the tuner on or off, just tap the footswitch. Notes regarding tuning and signal output:
- When the tuner is active, the output will automatically be muted for silent tuning.
- When the tuner is active and no signal is detected, four red LEDs will light on the bottom of the display, indicating that POLYTUNE 3 is ready for tuning.
- POLYTUNE 3 features a true bypass circuit that leaves your beloved tone unaltered when the tuner is bypassed.
Operation – Tuning with POLYTUNE 3
Chromatic vs. polyphonic tuning
A very simple guitar tuner will only allow you to tune open strings, one string at a time – e.g., E-A-D-G-B-E for the standard tuning of a guitar.
POLYTUNE 3 is a chromatic tuner – meaning it will detect and allow you to tune all twelve notes of the scale.
But that’s not all. Other than a traditional tuner, POLYTUNE 3 allows you to play all of your instrument’s string simultaneously when tuning. POLYTUNE 3 will detect which strings need to be tuned and indicate those strings in its display. This allows you to tune your instrument much faster.
Finally, you may have tuned one or all strings on your instrument differently from standard tuning, or you may be using a capo to change the playable length of the strings.
In all of these situations, POLYTUNE 3 has you covered.
If you press the display mode button on the rear of POLYTUNE 3 once, the currently selected display mode will be shown. Pressing the display mode button repeatedly will cycle through these modes:
- Guitar / Needle mode (indicated by a “G” and the center LED column lighting up).
- Guitar / Strobe mode (indicated by a “G” and the middle row of LEDs lighting up).
- Bass / Needle mode (indicated by a “B” and the center LED column lighting up).
- Bass / Strobe mode (indicated by a “B” and the middle row of LEDs lighting up).
In Needle mode, when you tune a single string, pitch is indicated by a column of five LEDs in the upper part of the display, and the name of the target note is displayed at the bottom of the display.
If the string you are tuning is too low, LEDs to the left of the center column will light up. If the string is too high, LEDs to the right of the center column will light up.
Tune the string until the middle column and the middle row of green LEDs lights up. This means you are “on target”.
- Red LEDs to the left (pitch too low) or to the right (pitch to high) of the center LED column
- Rotating segments in the display. The closer the detected frequency is to the target frequency, the slower the rotation.
Tune the string until the rotating pattern has come to a stop and only the middle column of green LED lights up.
As you know by now, POLYTUNE 3 is a polyphonic tuner. You can strum your instrument, and POLYTUNE 3 will analyze and display the tuning of all strings.
So how do you activate polyphonic tuning mode?
You don’t – it just works. Strum, tune, rock on!
Of course, only the strings that are actually present and played will be shown in the display. So if you tune a four string bass, only four LED columns will light up.
Drop D tuning
“Drop D” is a popular tuning (also known as D-A-D-G-B-E) in which the lowest string of a guitar is tuned down (“dropped”) from E to D.
If you want to tune an instrument set to “Drop D”, follow these steps:
- Press and hold the POLYTUNE 3 footswitch for about three seconds.
- The word “DROP” will be displayed briefly, and the default “ready for tuning” indicator at the bottom of the display will change from a small square to a “d”.
- If you want to switch POLYTUNE 3 back to standard tuning, press and hold the footswitch for three seconds again.
- “STD” will be displayed briefly, and the “ready for tuning” indicator will go back to a small square.
Alternate tunings and capos
There’s more to life than standard E-A-D-G-B-E tuning! You may have tuned all strings of your instruments down, or you may be using a capo. In that case, tell POLYTUNE 3 about your instrument’s tuning by pressing the TUNING MODE button.
If you press the TUNING MODE button once, the current tuning will be displayed (“– E –” for Standard Tuning). Pressing the tune button repeatedly will cycle through the following tunings:
If you do not touch the TUNING MODE button for two seconds, the display will blink twice, and the selected tuning will be used.
The selected tuning mode is stored and will be recalled when you power on POLYTUNE 3 again.
Changing the reference pitch
In most cases, you may want to tune to standard pitch, where the A above the middle C has a frequency of 440 Hz. However, you and your band may prefer a different pitch, or you may have to tune to an acoustic instrument that cannot easily be retuned.
In that case, you need to change the reference pitch.
To change the reference pitch, follow these steps:
- Press the DISPLAY MODE button and the TUNING MODE button (3) simultaneously.
- The display will show the current reference pitch (e.g., “440” for 440 Hz).
- To increase the reference pitch in 1 Hz steps, press the TUNING MODE button.
- To decrease reference pitch in 1 Hz steps, press the DISPLAY MODE button.
- To accept the currently displayed reference pitch and return to normal operation, do not press either button for two seconds.
The selected reference pitch is stored and will be recalled when you power on POLYTUNE 3 again.
Frequently Asked Questions (FAQ)
“I’m not hearing anything!”
When the tuner is active, the output will be muted for silent tuning.
“The pedal has power supply, but pressing the footswitch doesn’t do anything!”
To operate POLYTUNE 3, you need to connect an instrument to the pedal’s audio input jack.
“The display shows a red ‘#’ – what does this mean?”
This is the symbol of the Secret Brotherhood of the Tune-O-Calypse of Doom – and it is telling you that you are not playing loud enough…
Just kidding. This symbol shows that your POLYTUNE 3 is not bypassed and ready to display the pitches of your instrument’s strings. Please note that this also means that POLYTUNE 3’s audio output is muted. To unmute, press the footswitch.
“How do I get the best (most accurate) results?”
We have found that you will achieve the most accurate tuning of electric guitars in polyphonic mode by selecting the guitar’s neck pickup and using the thumb to strum the strings.
Operation – Bypass Mode
True Bypass and Buffered Bypass explained
True Bypass mode is a hard-wire bypass that gives absolutely no coloration of tone when the pedal is bypassed. This is the default mode for your effect pedal.
Using True Bypass on all pedals is a perfect choice in setups with a few pedals and relatively short cables before and after the pedals.
- you use a long cable between your guitar and the first pedal or
- if you use many pedals on your board or
- if you use a long cable from your board to the amp,
… then the best solution will most likely be to set the first and the last pedal in the signal chain to Buffered Bypass mode.
Can you hear the difference between a pedal in True Bypass or Buffered Bypass mode?
Maybe, maybe not – many factors apply: active vs. passive pick-ups, single-coil vs. humbucker, cable quality, amp impedance and more. We cannot give a single ultimate answer. Use your ears and find the best solution for your setup!
Switching between True Bypass and Buffered Bypass
To set the bypass mode, proceed as follows:
- Disconnect the pedal and turn it on its back.
- Unscrew the back plate of the pedal and look for the two small DIP-switches in the upper left corner.
- These two DIP switches offer three modes:
- Set the DIP switch to the desired position.
- Remount the back-plate.
Updating the firmware
TC may provide updates for the built-in software of your pedal, the firmware. Updating your TC pedal’s firmware requires…
- A computer running Microsoft Windows or OS X with a standard USB interface
- The specified DC power supply for your pedal.
