JOYO JMT-9009B Chromatic Tuner

We introduced polyphonic tuning to the world and since then guitarists everywhere have welcomed this next-generation way of tuning with open arms. PolyTune® Mini is the worldʼs smallest polyphonic tuner and it will fit on any pedal board. Sometimes size actually does matter and in such cases, PolyTune Mini is the perfect solution as no other pedal tuner in the world will take up so little space, which means more room for other pedals.  
PolyTune Mini shows you the tuning state of all strings simultaneously by simply strumming your guitar, allowing you to get back to playing in a matter of seconds. PolyTune Mini is among the most precise tuners in the world, tuning with +/- 0.5 cent precision in chromatic mode and +/- 1 cent accuracy in polyphonic mode. Also, it automatically switches between chromatic and polyphonic modes depending on whether you strum all strings at once or pick each string individually.  

Further, PolyTune Mini features Drop-D and Capo modes as well as True Bypass for zero tone coloration and a super-bright LED display. PolyTune Mini – Tiny Meets Awesome
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 PolyTune Mini – a downright tuning miracle! The original PolyTune was the world's first polyphonic tuner - a multiple patents pending, game-changing total tuning turnaround that will have future guitarists wondering how we ever got by without it.     PolyTune Mini Main Features

  Specialized tuning
  With its lively up-tempo sounds that feature various stringed instruments, bluegrass music is enjoyed by people all over the world. Korg has now created a dedicated tuner for bluegrass instruments ---
  The BA-40 allows you to tune bluegrass instruments including- banjo, fiddle, mandolin, resophonic guitar-in addition to standard guitar and bass. Perfect fifths are supported for fiddle tuning. The LCD meter-type display provides better than +/-1 cent accuracy, and features excellent visibility on stage or in the studio to ensure that you can tune easily and accurately.
  
  Accurate tuning
  With a detection range of E1@bbbbb (30.868 Hz) to C8 (4186 Hz), the BA-40 covers the entire range of instruments used in bluegrass music, and also allows you to adjust the pitch up or down in semitone (half note) steps so that you can use sharp/flat tunings relative to the standard tunings of these instruments. You can even tune your guitar with a capo still attached. Markings on the meter allow you to use a tuning reference in a range of 430 Hz to 450 Hz.
  
  *Even if the pitch is within range, detection may not be possible for instruments that produce large numbers of overtones, or for instruments that have very fast decay's.
  
  Sound Out mode
  The BA-40's Sound Out mode uses the internal speaker to play a reference tone of the correct pitch for each string of the instrument you're tuning. You'll be able to tune more accurately by using both eye and ear as well as train your sense of pitch by repeatedly listening to the reference tone.
  
  Bypass function
  The BA-40 provides an output jack that can be connected directly to your amp/speaker system. This allows you to leave your instrument connected to the tuner while you perform so you can easily check tuning at any time. By using the optional CM-100L contact microphone you can tune accurately even in noisy environments.
  
  Auto Power Off function
  The Auto Power Off function conserves battery life by automatically turning the power off when the unit is not in use for ten minutes.
