Ultra-compact, LCD Needle-Style Chromatic Tuners
High accuracy and superb functionality have made Korg tuners the worldwide favorite. And now, the new CA-30 joins the best-selling CA Series of tuners.

Wide Range of Pitch Detection
This compact chromatic tuner supports a broad range of C1 (32.70 Hz)--C8 (4186.01 Hz), allowing speedy and high-precision tuning of wind, string, keyboard, and other instruments. This tuner is ideal for tuning even low-register notes containing numerous overtones that are often difficult to tune. A high-sensitivity mic is built-in, allowing easy and accurate tuning of acoustic instruments such as ukuleles. A separately sold CM-100 contact mic can also be used to send the vibrations directly to the tuner for even more accurate tuning.

Ultra-compact Body with a "Tilt Slit"
Although the CA-30 is small, thin, and light, don't let its pocket-sized body fool you. The CA-30 packs read more the functionality needed for tuning a wide range of instruments. From studio to stage, tuning is easy and convenient. The back of the unit includes a unique arc-shaped "tilt slit" that lets you insert a plastic card for use as a handy stand.

High-Precision LCD Meter
The meter section uses a LCD needle, combining the accuracy of an LCD with the easy visibility of a needle, and providing a stable display. Additional visual feedback is provided by LEDs that indicate pitch deviation.

Sound Out--Internal Speaker Provides a Reference Pitch
In addition to visual tuning via meter, the CA-30 can play reference pitches from its internal speaker (Sound Out) for tuning by ear. Each press of the Sound switch will cycle through the A4--Bb4 notes commonly used for tuning wind instruments. Or you can hold down the Sound switch to change the cycle to the semitone intervals from C4 through C5 (one octave), allowing reference pitches for any instrument to be sounded quickly.

Calibration Function
The Calibration function (410--480 Hz) supports a wide range of standard pitches, and can be adjusted in 1 Hz steps for accurate and flexible tuning to any song or key. Thanks to the Memory Backup function, the Calibration and reference pitch are remembered even when the power is turned off. (However, these settings will be initialized when the batteries are replaced.)

Auto Power Off Function
If you leave the unit powered-on for 20 minutes without performing any operation, the Auto Power Off function will turn the power off automatically, avoiding unnecessary battery consumption.

Approximately 100 hours of Continuous Use
Low-power consumption design allows an amazing 100 hours (approximate) of continuous battery life (A4 continuous input, Meter mode, zinc-carbon batteries).

* Even if the pitch is within the detection range, detection may not be possible for instrumental sounds that contain a large number of overtones or have a rapid decay.

"Why get any other tuner?"
Overall: 10 out of 10 stars
Ease of Use
The Korg CA-30 is so simple to use that the instructions are not really needed.
The size is small enough to fit in a shirt pocket.
Now that it is available for less than $20.00, no instrument case, gig bag or accessory kit should be without a tuner.
