With superior features like a large, easy-to-read, LCD needle-style display, the Korg CA-40 Chromatic Tuner is a great value! Expect nothing but the best from this highly functional digital tuner!
With a wide range that covers A0 (27.50 Hz)〜C8 (4186.01Hz), you can tune a variety of instruments with the 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 requiring any other equipment. Alternatively, you can use the separately sold CM-200 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, making it easy to check the tuning even while you perform.
The pocket-sized CA-40 features a refined design with a stand on the back that lets you place the tuner on any surface. The CA-40’s display has been enlarged for even better 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.
In addition to letting you tune visually using the meter, the CA-40 provides a Sound Out function that plays a reference tone through the internal speaker, letting you 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 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.
The Auto Power Off function automatically turns the power off after the unit has been left on for twenty minutes, preventing the batteries from running down needlessly. 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).

That being said, it's tiny, lightweight, affordable, and seems to be accurate. I would rather pay more for one that was bigger and had a light.
So, the new CA-40 came today and I like it a lot. It is a tad larger than the older model. It has a fold-out tab on the back so you can stand it up at an angle. It seems to me that the digital pointer/indicator is more stable and sensitive in a good way. It feels like I can dial the tuning in with more precision.
I recommend this tuner. I like this one better than other model.
The CA40 is the one I use the most. Sure, the Intellitouch locks in to the pitch a little faster and you can just clip it on the headstock and leave it there as you practice, but it's three times the price, and if your guitar holds a tune then you really don't need a full-time tuner while you're playing. I bought the TM-40 for the metronome, but it takes more space in the guitar case, it seems to go through batteries faster, and it has more buttons and features than I really need, particularly at a gig. I use the metronome for practice, but I rarely take it out of the house.
The CA40 never leaves my guitar case. It's reliable, it's small, and it has a decent battery life. The only downside of the CA40 is that the internal microphone has a hard time locking in if you're using it in a noisy place (like a coffee shop just prior to an open mic when a bunch of guitarists are all tuning in the same room). My guitar has a pickup, so in noisy rooms I just plug in the CA40 with a 2' cable, and it works great. If you don't have a pickup, though, and you need to tune in a noisy environment, then the extra expense of the Intellitouch might be worth it.
Otherwise, though, the CA40 reliably gets the job done at a very reasonable price. No sense making things more complicated (and expensive) than they need to be.
My favorite feature is that I can be sure my drone strings are at exactly the same pitch. The Korg is also very useful in resetting your banjo after you have played the pegs to bend a note.
No, this is not a pro's tuner, but for all of us non-pros, it does it's job with a minimum of hassle. I'd recommend it strongly for beginners and for people like me who are turning several types of instruments.
