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.

Summary: "Easy to use and accurate"

I've used several Korg tuners over the years and bought this one last year for tuning guitar. It's lightweight, easy to use and has good battery life. Compared with other tuners, the Korg is more accurate than onboard guitar preamp tuners and locks onto a frequency more quickly than most clip-on ones. It's not as accurate or quick as a strobe or good software tuner, obviously, but it's certainly good enough for everyday use or even for setting intonation in a pinch. Some tuners have problems picking up lower frequencies such as the low E on a guitar or bass, but this one does a pretty good job most of the time. I'd recommend it to any guitarist as an essential to keep in their case.

Summary: "Korg CA-40 Tuner"

Seems to be accurate. I do not have to fine tune the guitar after using it like I did with my old tuner. Is easy to read considering my declining eyesight. Wish it had a backlight but other than that it is an excellent buy for the money. In fact, I may even buy another one for my backup guitar.

Summary: "Chromatic Tuner"

I purchased the Korg CA-40 Chromatic Tuner to help me tune my grandson's violin. It works great. With little musical ability, and no "ear" for notes, I am able to keep his violin in tune between lessons.

Summary: "Awesome for guitar tuning"

I love this tuner so far. I purchased it with the clip on microphone for my acoustics. It is very easy to use, the needle doesn't sway around wildly like a lot of other tuners I've seen. My guitars sound better than ever now, (My ear isn't good enough to tune to a tone). This should serve me for a lifetime, even if I pick up a banjo or mandolin later. I highly recommend getting the clip on mic with this, as you can tune up even in a noisy room.

Summary: "Best Value Chromatic Guitar Tuner"

This KORG CA-40 was purchased for a friend, but I have fallen in love with it and will give her one of my others!
It is extremely low priced but very accurate, fast to tune and very lightweight. Amazon supplied it through Austin Bazaars and they shipped it very quickly, well packed too.
How does it compare with the heap of other guitar tuners I have? For accuracy and speed, it is right up there with it's much more expensive KORG cousins but still has the imporant features like being auto chromatic, 1/4 inch guitar input & output sockets, sound out, large easy to read display and high accuracy.
It compares well to Boss mid range tuners and is FAR superior to Planet Waves and intellitouch products. It is more lightly built than a lot of the very expensive tuners, and it lacks a travel case - but hey for $15 you get a very sweet deal!
I feel it really is the best value, low priced, high accuracy guitar tuner on the market today. If it gets stolen, you sure won't lose any sleep over it, like I did when I lost my expensive BOSS a couple of years back!
