KORG Tuner GT-4 Guitar and Bass

A wide range of Support:

It can support seven-string guitars (7 Si at 1 Mi) in Guitar mode and six-string bass (If Low and High C) in bass mode and can quickly indicate pitch with great accuracy.
It also has a built-in high sensitivity microphone for tuning acoustic guitars.

Three Tuning Modes:

You can choose one of three modes (strobe, mirror and counter) and the LEDs will indicate the tuning mode. Triangular green tuning guides indicate whether the input is Dièze or Bémol and signal when the instrument is perfectly tuned:

Strobe mode:
The red LEDs will start spinning when you play a note on your instrument and will stop when the instrument is tuned. The LEDs will continue to turn clockwise if your instrument is Sharp or in the other if your instrument is flat. When the setting is correct, both tuning guides will be lit simultaneously.

Mirror mode:
The red LEDs indicate the tone of your instrument. Just tune your instrument so that the red LEDs coincide with the less brilliant red LEDs. The bright red LED will move to the left or to the right if the input pitch is Dièze or Bémol.

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