Flexible, precise and compact tunner

Great tuner with big and clear display despite being compact. You can connect your instrument directly (for better results), or just place it nearby to use the incorporated microphone (supporting acoustic instruments). More precise than most apps, clip-on, and pedal tuners.

This is not in the pedal format, so it is not possible to silence the signal while tuning. If you really need that, Korg has a pedal tuner with a similar display, for twice the price.
