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!
