The PolyTune 2 Mini is the world's smallest polyphonic tuner. It offers ultra-fast, ultra-precise tuning in a minimal footprint. It overcomes the challenge of packing 109 ultra-bright LEDs into its small display, allowing you to instantly check the tuning status with a clear display at any time. Tuning accuracy is +/- 0.1 cent, boasting an accuracy of 1/1000th of a semitone. Whether you want to tune quickly on stage or tune as accurately as possible, the Polytune 2 Mini provides the optimal tuning solution. Due to its true bypass design, it does not affect the tone of the instrument when the effect is off.
