Tuning comes full circle
The DT-4 is a unique style of chromatic tuner in which LEDs around its circumference indicate how close the input pitch is to the note name displayed in the center. In spite of its compact size (it 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.

Three new tuning modes
The DT-4 illuminates the green LEDs around its circumference in one of three tuning modes: Strobe, Mirror, or Meter. There are also triangular red tuning guides that indicate whether the input is sharp or flat, helping you tune your instrument more precisely.

Strobe mode
The green LEDs will stop moving when your instrument is in tune. The LEDs will move in a clockwise direction if the pitch of your instrument is sharp, or counterclockwise if it is flat. When the tuning is correct, the two tuning guides will also light simultaneously.

Mirror mode
Mirror mode is a new concept of tuning found only in Korg tuners. When the two dim green LEDs at the lower left and right coincide, you're perfectly tuned. The bright green LED will move to the right of center if the input pitch is sharp, or to the left if it is flat. The distance between the bright green and dim green LED's indicate the distance to perfect tuning.

Meter mode
Tune your instrument so that the bright green LED is aligned with the red tuning guide in the center as on a conventional needle type tuner.

Designed for easy operation
The DT-4 is designed for effortless operation, with switches conveniently located when held in the palm of your hand.
In Strobe mode if approximately thirty seconds have elapsed without any audio input, the rotating red LEDs will go dark. If approximately ten minutes have elapsed with no audio input while powered-on, the DT-4 will automatically turn off to prevent unnecessary battery consumption.

Worst tuner ever.

Comments about Korg DT-4 Chromatic Compact Strobe Tuner:

dont buy this tuner. Everytime i tuned a string the note name would change to random notes and would say that strings were tuned then when you pluck it again it says its sharp/flat or even a different note. after having it for a week i bought a different tuner and have had no problems with it.
