Korg CA-2 Chromatic Tuner

The meter scale of the CA-2 includes markings to indicate pure major and minor thirds relative to a specified pitch. Simply by tuning your instrument to these markings, you can perform beautiful, pure harmonies when playing in an ensemble.

The calibration function (410-480 Hz) can be adjusted in 1 Hz steps for accurate and flexible tuning to any song or key.

In addition to tuning visually with the meter, you can also tune by ear using a Sound Out mode that's chromatically adjustable in the range of C4–C5.

The high-efficiency long-life design allows approximately 100 hours of continuous operation on two AAA zinc-carbon batteries or approximately 200 hours on alkaline batteries.

Features:

• A needle-style meter with large high-visibility note name and string name
• A compact body that's slim and lightweight
