    I'm struggling to find a definitive answer on this...

    The big Polytune has a bass mode, and works well for both chromatic and polyphonic tuning on a 5 string bass.

    The Minis seem to lack a bass mode, so I'm wondering how (if at all) they work with a 5 string bass in Polyphonic mode.

    Any guidance much apprecaited.

      PedroRodrigues Hi foldyman, thank you for your post, you are correct the Polytune 3 mini does not have a dedicated bass mode but offers polyphonic mode and will work on 5 string bass.
      The unit offers a Piano tuning range that will be compatible with your tuning requires
      The unit will work with 4 and 5 String bass.
      Thank you

    When I am at home or using in low ambient noise, it works perfectly. 

    But when I am at a gig with high ambient noise, it doesn't detect the signal and the gauge swings erraticaly without homing in on the string signal. It doesn't work in multi string or single string modes. 

    It looks like the ambient noise is "confusing" it, which is of course inconcievable given that the signal is sent via the guitar cable. 

    Any thoughts / suggestions?

      PedroRodrigues Hi tremoloarm, please consider that is an odd behavior as the unit receives the signal for tuning exclusively via 1/4 JACK TS not suffering any external interference, the only thing I can think of is that if you use the unit on a pedal board when on a gig that might not provide the correct voltage that the unit requires. The unit requires a Standard 9V DC, centre negative >100 mA. It may also be advisable to check your cables and look closely to any differences on your set up when you are at a gig, maybe using the unit on a different position on the pedal board. If none of these steps helps in nay way I would suggest to follow the link below and submit an assistance request directly with our Tech support Team so we can assist you with more tools. Thank you

    Can someone point me to the FAQ on how to get the Polytune out of boot mode? I tried to update the firmware, but it got stuck and now I can't unstick it. 

    I downloaded the "PolyTune_SWUPdater" and "setup" file, and followed all the instructions on the release notes page

    The issue seems to be that the SW Updater is designed to work in Windows XP, not Windows 10. I tried to run various compatability settings (like running the program in compatability mode for Win XP), but it doesn't let me run the SW Updater, so I can't update the firmware (and its now stuck in the boot mode).

    I read that you can run the SW Updater program from an old Windows XP computer and get it to work, but I really don't have any of those around, or know anyone who does.

    Can someone please help?

    I'm trying to decide between the regular Polytune 3 and the Mini version, I like the Mini's size, and that it has the switches on the outside, but is it possible to upgrade the Mini's firmware?  I don't see anything like a USB connector like the regular Polytune 3 has, and there don't seem to be any software updates on the product page. 


    Thank you!

      Dale_M Hi there, no there is no software updates available for the mini as it does not have a USB port, only the full size Polytune 3 offers this advantage.

      • Is it possible to update firmware on Polytune 3 Mini?
        MTGuitar I figured that was the case, I just wanted to confirm. Thank you for your response!

    Just purchased a TC Polytune 3

    Not arrived yet.

    To save me taking my pedal board appart to get acces to the power cables i'm considering using a battery with this.

    Does anybody know whether the Polytune draws power whilst connected - even when the unit is off?

    Whilst connected, how long will a standard alkaline battery last during constant use (true bypass mode)

      PedroRodrigues Hi Chedmus, please consider that the Polytune 3 will draw voltage even when off , it draws lower voltage but it does draw energy. Thank you

    I recently learned about sweetened guitar tuning (tuning each string a few cents flat to accoomodate for fretting chords etc for optimal intonation during play) and wonder if the Unitune can be used to do this (tune a string anywhere from 4 to 12 cents flat, varying by the string).

    I was able to do flat tuning with a Korg CA (essential for African instruments) but want a clip-on for guitar and am wondering which one to get. I prefer the Unitune otherwise, but am unsure about the tuning increments. It looks like a line of lights is an interval of some kind, so I wonder if it's 1 cent, or more than that, perhaps 5 cents?

    hey guys,

    I just got my polytune 3 today. worked great and loved it. updated firmware to 1.4 and now it does not recognize my 5 string bass. It tunes great for individual strings but only shows 4 strings when I strum. 

    Thanks a ton,

      PedroRodrigues Hi jlittle, please consider that 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 centre 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 centre 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 centre column will light up. If the string is too high, LEDs to the right of the centre 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”.

      In Strobe mode, the difference between the correct (target) frequency and the actual detected frequency is displayed by two indicators simultaneously:

      1. Red LEDs to the left (pitch too low) or to the right (pitch to high) of the centre LED column
      2. 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, POLYTUNE 3 is a polyphonic tuner, you can strum your instrument, and POLYTUNE 3 will analyse and display the tuning of all strings.
      So, you don’t need to activate the polyphonic tuning mode, it just works. Please Strum and tune. (PLEASE SEE THE IMAGE BELOW)

      Please consider that only the strings that are actually present and played will be shown in the display.
      Therefor if you tune a four string bass, only four LED columns will light up.

    • jlittle3917
      jlittle3917 Thank you for the quick response. I am currently in bass strobe mode. Tunes great! but the strum mode is only showing me four strings even when I am hitting all 5 on my bass. Prior to the 1.4 firmware update this was working fine and has never been a problem on my previous polytune.

      jschulze I made the mistake of "upgrading" the firmware on my new Polytune 3 right when I got it too. After about a month of back and forth with the support team, it turns out that the pedal I received actually had firmware revision 1211 loaded from the factory, but the software updater posted on TC Electronic's website was an older revision (1136, listed as 1.4.00 on the website). So I actually downgraded my pedal by running the 1.4.00 software updater from the website. I kept pestering the support team to post the latest firmware, and it looks like it was just posted today, version 1.4.08 (although there's nothing that says the revision, but hopefully it's 1211).

    Unitune Clip purchased 1 month ago shows only one display. When Display Mode Button is pushed, nothing happens. Display shown is horizontal green LED line with short vertical green 
    LED line with red LEDs to either side to indicate flat/sharp.

    Anyone else have this problem?

      PedroRodrigues Hi BigHick11,please consider that to you must press the button identified with an arrow in red on the image below to allow you to change between Needle and Strobe tuning modes.
      Please consider that secondary display shows the detected note name for the currently-tuned string identified by an arrow in blue

      Thank you

        BigHick11 Hi Pedro,

        I am aware of the Display Mode Button, which I mentioned in my original post. Could you please confirm that there are 2 different displays - 1 for Strobe Mode and 1 for Needle Mode. I am only seeing 1 display when button is pushed.
