The Korg CA- 2 Guitar/Instrument Chromatic Tuner offers quick and precise tuning, in a stylish, compact, hand-held unit. A clear display screen features a needle-style meter with large high-visibility note name and string name for pitch accuracy. The CA-2 is equipped with a wide pitch range, and accommodates a variety of instruments. An adjustable calibration of 410-480Hz offers a wide range of concert pitches, and a sound mode emits a reference tone from the built-in speaker for easy usability. Players can benefit from up to 200 hours of continuous usage with two AAA alkaline batteries.

String players will love the large display screen that features a needle-style meter, with perfect pitch accuracy. This screen provides note and string name, along with red and green LEDs for pitch indication.

The CA-2 features a compact body profile, that can fit inside any instrument case. This credit-card sized unit is perfectly rounded, accommodating any hand shape and offering comfortable usability. A new mechanism allows the battery compartment to be easily removed for quick and easy replacement. The battery cover simply slides over the entire body, eliminating the risk of misplacement.

The CA-2 features a high-sensitivity built-in microphone and accommodates a variety of A0-C8, allowing speedy and high-precision tuning of wind, string, keyboard, and other instruments. For added versatility, an optional CM-200 contact microphone (sold separately) can be used to send the vibrations directly to the tuner for even more accurate tuning.

Inaccuracies of the harmonies in a triad are particularly easy to notice when played by a brass band or orchestra, and by adjusting the pitch of a major or minor third relative to the equal-tempered interval, an excellent third can be reached. From precise intonation, the meter scale of the CA-2 includes markings to indicate pure major and minor thirds relative to a specified pitch. By tuning the instrument to these markings, players can achieve beautiful, pure harmonies when playing in group applications. If that's not enough the CA-2 also offers an adjustable calibration function of 410 to 480 Hz which can be adjusted in 1 Hz steps for accurate and flexible tuning to any song or key.

As well as offering quick and precise tuning, the CA-2 tuner also features a high-efficiency long-life design, offering up to 100 hours of continuous operation when used with two AAA zinc-carbon batteries, or approximately 200 hours on alkaline batteries.
