With a size similar to an audiocassette case, the KORG CA-1 chromatic tuner 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 orchestral 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-1 Chromatic Tuner is small, thin, and light, don't let its pocket-sized body fool you. The CA-1 chromatic tuner 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
In addition to visual tuning via meter, the CA-1 band and orchestra tuner 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.

Adjustable Calibration
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
The power will turn off automatically, if the unit is left powered-on for 20 minutes without performing any operation, 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.

By Courtney

from Pittsburgh, PA

Comments about Korg CA-1 Chromatic Tuner:

This tuner is not for solo string instruments due to the fact that it picks up ambient house noise. Does not accurately tune flats and sharps. **note: this item was tested on a 2 1/2 octave harp.

korg ca-1 chromatic solo tuner

By Nobody Cares

from bismarck, north dakota

Comments about Korg CA-1 Chromatic Tuner:

I've owned 3 tuners now and this one is the worst and most expensive of the 3. Acoustic tuning picks up on any noises around you making tuning difficult in almost any environment and it also seems to have a problem distinguishing between high E and A which can be frustrating at times. It also dont have a flat function for easy drop tuning. Personally I will stick to my belcat tuner.

Great for the Price

By Adam S.

from Minnesota

Comments about Korg CA-1 Chromatic Tuner:

This is a great tuner for the price. I really like. I haven't had it for long so I can not account to it's durability but it helped me tune my acoustic. I have been borrowing my brother's Qwik Tune tuner for a few months and it didn't pick up the acoustic sounds nearly as well as this little tuner does. All in all, an awesome tuner. Korg really does do quality work.

Not worth the money

By Steven

from Winston-Salem, NC

Comments about Korg CA-1 Chromatic Tuner:

As a professional trombonist and active guitarist, I am very disappointed with this tuner. Having owned a Korg CA-20 for years, I had high expectations. This tuner does not pick up the low register of the bass trombone like my CA-20. It also does not distinguish between notes accurately in automatic detection mode for both the trombone and the guitar. Bottom line, I wish I could get my money back.

By Guitar Center 4 Life

from san jose california

Comments about Korg CA-1 Chromatic Tuner:

I'm a beginner guitar player and this tuner is perfect! I have had several others but they don't compare to this! not only does it tune guitar... but it also tunes any other other instrument possible! it is very accurate and can be plugged into your guitar/bass to get the greatest tuning possible. it is the best tuner i have seen so far and has an amazing price tag! so if i were you i would shut down your computer and drive to the nearest guitar center! :)

Great tuner.

By James

from Phoenix, Az

Comments about Korg CA-1 Chromatic Tuner:

I've had this tuner for 2 months, and it's never let me down. I don't know what the other guy is talking about the sharp/flat function, it DOES display sharps/flats when you're playing them so you can get into drop tunings easily. Hands down the best tuner I've owned for the price.

Korg CA-30 BETTER!!

By Jesse

from Laredo, Texas

Comments about Korg CA-1 Chromatic Tuner:

If you are looking for a great tuner for a good price the Korg CA-30 is a better tuner than this one. Iv'e compared both of them and this tuner is the same price as the CA-30, but of course the CA-30 is better. I prefer the CA-30 because of its durability NOT THAT I RECOMEND DOING THIS BUT (YOU CAN DROP IT MILLIONS OF TIMES AND IT WILL STILL WORK!) and it can recognize all of the notes playable on guitar, bass, and other instruments YES I MEAN HALF STEP AND DROP D AND ALL THAT GOOD STUFF WITH MORE! :)

Pretty good device

By Dylan

from Wisconsin

Comments about Korg CA-1 Chromatic Tuner:

This is a great tuner for tuning an acoustic. I havent tried it on an electric yet, but I can't wait to. The mic inside can pick up a tone really easily, but the bad part is it can pick up noises throughout the house too. If you are looking for a good tuner, get this one.
