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.

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!

More than adequate, especially for the price

By Josh Rowson

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:

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 .

      Very nice little tuner

      By Ryan Neill

      from Cleveland, OH

      Comments about Korg CA-40 Electronic Chromatic Tuner:

      Pretty much said everything in other sections. This thing is nifty.
      for $13.99 you don't expect much, features-wise BUT the thing comes with a short book of things that you can do with it. I bought it for my 12 string I just purchased from ebay and while the 12 string doesn't stay in tune so well, this tuner is very helpful. haven't tried it on the bass yet but from what I read about it, you can tune a piano with it.
      It's small, very good microphone on it (picks up on pretty much any sound and tunes to the loudest note type sound), takes two AAA batteries and yes two come with it. It turns itself off when you forget to it seems. Don't know what else to say here. Screen and visualization is very good, helps with my wonky above mentioned 12 string.
      This is where it really outshines the other tuners you might look at. $14 and featureful and sturdy, not going to find a better deal on a new tuner... maybe if you found one of these in a garage sale for 50 cents you could say you got a better deal.

      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.

      CA-40 Excellent Product

      By Glenn

      Comments about Korg CA-40 Electronic Chromatic Tuner:

      I purchased the CA-40 Electronic Chromatic tuner for my daughter's accoustic guitar lessons. After a couple of sessions using another brand of tuner, her instructor, a long time professional musician, commented that her guitar was not quite in tune and suggested we purchase another tuner. After purchasing the CA-40 (and not telling the instuctor) he was surprised that her guitar was accurately tuned and attributed it to having not practiced or having bought another tuner. My daughter confessed to the purchase and her instructor was pleased. The CA-40 is very easy to use and comes with good instructions, and based on her instructor's observations, is accurate.
      A large, easy to read meter, makes tuning easy.
      Upon using the tuner for the first time, we could see that the meter was easy to read and the casing sturdy enough to take some abuse.
      Compared to two other tuners that I have purchased, the CA-40 offers more features for a lesser price.

        I purchased this for intonation training on saxophone, great! It works for voice too.
        Then I discovered alternate guitar tunings, fabulous!
        Also you can plug it inline down with your pedals and see the lights well enough to tune on stage.

              Comments about Korg CA-40 Electronic Chromatic Tuner:

              For being a generic-looking inexpensive tuner, the Korg CA-40 is great. It does exactly what I need it to do, which is tune any electric instrument accurately. It goes to (5 cents I believe) which is accurate enough for recording, but not painstakingly pin-pointed so as to make tuning a 30 minute ordeal. I get recording ready tunings in about 40 seconds on a regular 6 string guitar.

              As a plus, I know many larger studios use this as standard tuning gear.
