The CA-2 from Korg is a chromatic tuner with a wide range of pitch detection which allows for fast, high-precision tuning of winds, strings, keyboards, and other instruments.
The CA-2 offers needle-style metering which shows the pitch quickly and accurately. For smooth tuning, the large, high-visibility display area lets you know the note and string name, while the red/green LEDs indicate pitch discrepancy.
Features include an adjustable calibration function for a wide range of concert pitches, pure major/minor third markings to help you perform pure harmonies when playing in an ensemble, and a Sound mode that lets you tune by ear.
Compact and lightweight (at 2.36 oz), the CA-2 is easy to carry anywhere, and its stylish, rounded body is comfortable to hold in your hand. The high-efficiency, long-life design affords you approximately 200 hours of tuning, on two AAA alkaline batteries.
