Korg CA-2 Guitar/Instrument Chromatic Tuner

Korg CA-2 Chromatic Tuner – Compact, Accurate, and Easy to Use

The Korg CA-2 delivers high precision, sensitivity, and simple ease of use, making it a reliable choice for musicians of all levels. It provides stable tuning functionality in any situation, from personal practice to ensemble rehearsals and concert performances.

Needle-Style Meter with High-Visibility Display

The CA-2 features Korg’s signature needle-style meter, ensuring fast and accurate pitch detection. The note name and string name display area is now approximately four times larger, making it easier to read. Red and green LEDs indicate pitch discrepancies for even smoother tuning.

Compact, Slim, and Lightweight Design

Designed for portability, the CA-2 is a pocket-sized, card-type tuner that fits easily in any case or bag. The rounded body is comfortable to hold, and the redesigned battery compartment allows for quick and easy battery replacement without the risk of losing the cover.

Versatile Tuning Functions for a Variety of Instruments

With a broad pitch detection range of A0–C8, the CA-2 can accurately tune wind, string, keyboard, and other instruments. The built-in high-sensitivity microphone ensures precise tuning, while an optional CM-200 contact microphone can be used for even greater accuracy by detecting vibrations directly from the instrument.

Pure Major and Minor Third Markings

For ensemble musicians, tuning to pure major and minor thirds can significantly enhance harmonic accuracy. The CA-2 includes meter scale markings to help achieve pure harmonies when playing in a group setting.

Adjustable Calibration for Flexible Tuning

The calibration function, adjustable from 410–480 Hz in 1 Hz steps, allows for precise tuning to match different concert pitches and musical styles.

Sound Mode for Tuning by Ear

In addition to visual tuning with the meter, the CA-2 features a Sound Out mode that emits a reference tone from the built-in speaker. This mode is adjustable within the range of C4–C5 for ear training and pitch matching.

Long Battery Life for Extended Use

The CA-2 is designed for efficiency, offering up to 100 hours of continuous operation with two AAA zinc-carbon batteries or up to 200 hours with alkaline batteries.
