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.
