In spite of the Korg DT-4's compact size (fits in the palm of your hand), the illuminated circumference and large note name display provide excellent visibility, allowing high-precision tuning over a range of A0 (27.50 Hz) - C8 (4186.01 Hz). The adjustable calibration lets you specify the reference pitch in a range of 410 Hz - 480 Hz (1 Hz steps). Its design emphasizes comfort and ease of use, with function-selecting switches placed for quick and easy access.
