A versatile tuner with extended range.

The Korg CA-40 Electronic Chromatic Tuner is equipped with an output jack so you can stay plugged. An extra-large LCD screen gives you excellent visibility. Adjustable calibration range (410-480Hz). Tunes 6- and 7-string guitars and 4-, 5-, and 6-string basses. Pure major/minor 3rd pitch indication marks. "Quinta" flat tuning lets you tune down as much as 5 semitones. Features reference tone, mic, speaker, and folding stand. Auto power off and memory backup. Batteries included.

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 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.

Korg tuners and metronomes purchased from a Korg USA authorized dealer now have a three year warranty.

This product has great versatility. I can take it from my bass guitar and go to Jazz Band and use it on my Bari Sax. It is pocket sized too- perfect for running around during state music competitions. I am scared that I will break off the little stand, though.

Best Tuner I Have Owned

The tuner does what it is supposed to in a friendly manner with no qualms. It is very durable and has survived several drops from waist height without damage. It uses easy to find AA batteries that last at least a year without replacement. Dependable. A cool way to tune.

I bought one of these a really long time ago. It's great that you have the option to calibrate the tuner away from 440. The low batter icon is also a nice touch. It's been dropped a lot and no damage at all. For a tuner that is in the lower end of the price spectrum, it's accurate and it holds up. It would be cool if they offered this in a pedal tuner setup. Maybe they do and I don't know.

Great tuner

I got this tuner and I gotta say - it's awesome. The fact that it tunes up to six steps down means it's really useful for different tunings (drop D, C#, etc.) and the dial is pretty smooth. This tuner is a great deal for the money.

I bought this tuner because the one that came with my bass pack only did standard tunings...I must say that it is a life saver, very accurate and east to use just plug and play.
