OVERVIEW

Superior features include a large, easy-to-read, LCD needle-style display.

The Korg CA-40 Electronic Chromatic Tuner has 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.

Approximately 85 hours of continuous use
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).

* Even if a sound is within the detectable pitch range, detection may be unsuccessful for instrumental sounds that contain a large number of overtones or decay rapidly.

** The calibration setting and the Sound Out reference pitch are remembered even when you turn off the power. However, when you replace the batteries, these settings will be initialized to the default values; the calibration will return to 440 Hz, and the Sound Out reference pitch will return to A.

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

This tuner does was it's supposed to do, and has never given me any problems. Tuning accuracy is very good, through either the 1/4" jack or the built-in mic. After a tune-up with this guy I'm always precisely in tune. There are no fancy features, but it does what it does well. It's also small, easy-to-read (even in the dark), and very easy to understand. I've used it daily, and still haven't had to replace the batteries.

The price is reasonable, and this tuner does what it's designed to: tune your instrument. I recommend it; it's a good buy for the price.

This is an easy to use tuner. However it did not last with very infrequent use. Purchased to use as tuner for lap steel guitar that requires temper tuning. Never went through the original set of batteries. Is good for inexpensive tuner for temper tuning.

I order these constantly for my guitar students and wish they would keep more in stock (they are always on back order). Very accurate and easy to work with. Works great on alternate tunings.

Great Bargain

Comments about Korg CA-40 Electronic Chromatic Tuner:

I purchased a clip-on tuner a few weeks ago for my bass that got great reviews. It could not seem to recognize the E and A strings. After some frustration, I picked up this Korg CA-40. It is super easy to use and works perfectly. The quality far exceeds my expectations at this price point. This is a no-brainer if you need a tuner. Highly recommended!

Awesome

By Valerie Ball

Comments about Korg CA-40 Electronic Chromatic Tuner:

Very Great Value And Great Buy
This tuner is perfect for my cello and my little brother's violin. It is very precise and it helps my intonation all the time . I also have a comp. coming up and without my tuner I don't think I would have been properly prepared . It was a great buy. The tuner has a strong battery and doesn't require a long setup , just take it out the package and boom , use it .
Very well worth it over those more expensive tuners .

    I could not get this product to hit the "O" mark at all. It would jump from left then to the right. I had Brand New Duracell Batteries in it also.

        I was super satisfied with my purchase. I use it with my concert ukulele. It's very accurate and easy to use. I'm a beginner and tone deaf and I had no issues tuning it perfectly!

        More than adequate, especially for the price

        Comments about Korg CA-40 Electronic Chromatic Tuner:

        Bought one of these from MF a while back because i needed a chromatic tuner instead of just my simple guitar/bass tuner. This things is fairly precise and i'm very pleased with what you get for the price but it didnt have the range to tune my piano because the really low notes and really high notes wouldnt register. Also, it has recently begun to randomly misread which note i'm tuning as i let teh note ring and try and change it (especially on my acoustic guitars) I'm not sure if its picking up background noise or echos or what but its kinda annoying. Don't let these complaints turn you off the tuner too much though because it was a stretch just to find 2 things to complain about this tuner and without spending 5x the price, your probably not gonna get anything noticeably better

        Comments about Korg CA-40 Electronic Chromatic Tuner:

        This is an pretty good tuner. You can tune both bass and guitar with this tuner and you can take it anywhere because of it's size. The only problem I have is when I'm tuning my bass it says I'm tuning a different string.
