How to Tune an Acoustic Guitar With the Korg CA-30 Chromatic Tuner
- 1). Place the Korg tuner on a flat surface face-up about 2 to 4 feet from your acoustic guitar's opening. Press the red power button to turn on the tuner.
- 2). Use one hand to pluck the thickest string, the E-string. The microphone on the tuner will pick up the sound. Loosen and tighten the tuning key until the letter "E" appears on the screen of the tuner. An arrow will move to the left and right of the screen indicating a flat or sharp note. A perfect tuning is achieved when the arrow lies in the center of the screen.
- 3). Repeat this procedure for each string that you tune.
