Does not work as expected
I used to own a Korg electric tuner that received so much use that it finally died after many years of operation. I attempted to replace the unit and ordered the GA-40, which seemed to me to be a newer version of what I had before based on the advertisement I read on Amazon. This particular device does not work as I had expected it to. The old device simply showed what note was played and whether it was sharp or flat. This device does not do that. It only detects and displays "E", "A", "D", "G", "B", or "E" when in guitar mode. It has a "Flat" mode that I cannot understand. The advertisement lead me to believe that it would be able to tune alternate (lower) tuning, which it does not do well. One of my guitars is tuned down two steps. The low string is tuned to C (verified with another tuner) but still registers an E on this thing, but you have to press the Flat key a few times before it will even show up. Not useful. I will be purchasing another product.

My unit is a in-KORG-ible waffler (Updated)
By Nigel Tufnel
It's just OK, but I prefer my phone app. The meter on this Korg GA-40 is just way to jumpy. Your flat...still flat...still flat...Perf...no, too sharp...still sharp....still sharp...Perfe....NO, now your flat again...still flat, etc. Kinda like trying to balance an egg on its end. A lot of times it fails to react at all and I have to wait a few seconds. Thats no big deal, but still kind of annoying. My phone app and this Korg do not agree. I may buy a Snark just for the tie breaking 3rd vote.
EDIT!: I'm going to give it 5 stars after all. I have to 'fess up to user error. I had been laying the unit flat on my desk. This time I used the little fold out stand and meter lost its nervous bounching around and responded to every pluck of the string. I guess the Korg was picking up some kind of resonance from my desktop that caused it to be confused. Also, I loaded a 3rd tuning app on my tablet for the tie-breaker. This new 3rd app and the Korg unit were in complete agreement.

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.
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.
A great product. Will recommend again.
