Large, easy-to-read, LCD needle-style display.

Built-in tuner for tuning to reference tones.

Wide Detection Range
With a wide range that covers A0 (27.50 Hz) - C8 (4186.01 Hz), you can tune a variety of instruments with the Korg CA-40, including wind, string, and keyboard instruments. The pitch and range are detected quickly and accurately. You can use the built-in high-sensitivity microphone to detect the pitch of an acoustic instrument without the need for any other equipment. Alternatively, you can use the separately sold CM-100 contact microphone to send the vibration of the instrument directly to the tuner, so that you can tune accurately without worrying about other sounds in the environment. An output jack (bypass) has been added to this digital tuner, making it easy to check the tuning even while you perform.

Conveniently Thin and Compact
The pocket-sized CA-40 features a refined design with a stand on the back that lets you place this digital tuner on any surface.

Large, High-Precision LCD Meter
The CA-40's display has been enlarged for even clearer visibility. In addition to providing both the accuracy of an LCD and the easy viewing of a needle-style meter, red and green LEDs are also provided to indicate pitch deviations, making tuning smooth and easy.

Sound Out Function
In addition to letting you tune visually using the meter, this digital tuner provides a Sound Out function that plays a reference tone through the internal speaker, allowing you to tune by ear. You can adjust the reference tone in semitone steps over a range of C4 through C5 (one octave) to accommodate a variety of instruments. Since the reference tone you specify is remembered, it's easy to sound it again whenever you need to.

Adjustable Calibration
The Calibration function of this hand held tuner lets you adjust the pitch in 1 Hz steps over a range of 410 - 480 Hz in order to accommodate a variety of concert pitches, giving you the flexibility to tune accurately to any song or key. There's also a memory backup function that preserves the Calibration setting and Sound Out settings even when you turn off the power.

Auto Power Off Function
The power of this digital tuner will turn off automatically if the unit is left powered-on for 20 minutes without performing any operation, avoiding unnecessary battery consumption.

Long Battery Life
The CA-40 is designed for long battery life, and allows approximately 85 hours of continuous use (continuous A4 input, Meter mode, zinc-carbon batteries).

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

5.0 out of 5 stars Help for aTin Ear, May 27, 2007

I am not a musician, but I love "playing" the ukulele as a way to amuse myself and relax at the end of a long day. Unfortunately I have trouble tuning my instrument because I am not so blessed with a tin ear. I have trouble determining when I have my uke strings in tune. I can get close, but often an off pitch string sounds OK to me.

I really never heard of an electronic tuner before I discovered the Korg CA-40 as a recommended product based on my purchasing history on the [...]. The price tag on the thing was so cheap I thought I could buy one and gamble that it was a remedy for my problem tuning the ukulele.

The tuner arrived and I was amazed at how easy it was to use and how nice my ukulele sounded once it was tuned properly. The Korg CA-40 "listens" to a string and an easily read screen along with a series of lights tell me what note a given string is sounding. The device automatically shows if a string is sharp or flat so I know to tighten or loosen it on the way to the proper sound.

I read some reviews of the Korg CA-40 by real musicians and was quickly intimidated by jargon and comments I didn't understand. I thought the tuner might be something a genuine amateur would find overly complicated to use. Not so--actually the tuner is probably more useful to a novice with a dumb ear than to the pro with perfect pitch. This thing is a winner.

5.0 out of 5 stars really fine tuner, April 5, 2008

I'm a professional classical musician, play viola, and use this every day. I usually use it with the Korg CM-100 tuner clip, which makes it even faster and more accurate, faster and more accurate IMO than the KORG OT-12 which costs much more. I also find it more accurate than the CA-30. It can easily track one note per second, and if my pitch is very accurate so it doesn't have to hunt much, it can even zero in in half a second, so I can actually practice passages with it. Batteries last a LONG time. A truly excellent tuner.

I just purchased one of these little tuners from Amazon last week. Though my guitar is low quality, (that's the next thing I'm going to buy) tuning it using only the meter mode of the tuner made it sound quite good, much better than my ear tuning. This thing is sensitive, accurate, and incredibly easy to use. What else do you want?
