    Does what it should
    The read out on the Korg tuner is on the small side and pretty low light. I put a Boss clip on tuner I own in the pic to compare. The Korg has an external mic which the Boss doesn't have. Both work when tuning a curved soprano sax - that's the sax neck in the pic. I have a tough time centering the needle when I sing notes with the Korg tuner but I expect that is my fault and not the tuner's. On sax I can center the needle on both tuners. Both tuners showed a steady centered A when I tested them with a tuning fork. The Korg takes two aaa batteries, the Boss one lithium.

    5.0 out of 5 stars Best student tuner
    Reviewed in the United States on December 16, 2013
    Style: CA-1 Chromatic TunerVerified Purchase
    Perfect tuner for the less-demanding situations: Chromatic, accepting a wide compass of notes, it offers deliberate "scordatura" mis-tuning options in 1 Hz steps. The LEDs and the "meter pointer" LCD display give maybe 1 or 2-cent resolution. There is also a "singing" mode in which the tuner emits the tone instead of listening to yours. Although the default tuning notes are A and Bb, it can play any note.

    Tuning your own instrument in a noisy environment is always a problem, and I think some of the expensive tuners are smarter about picking your instrument out of the mass of people tuning up. The optional plug-in contact microphone may be necessary.

    Battery life is good, as are physical ruggedness and ease of use. Doesn't take up much room in the gig bag. The dual-mode display gives good visibility in darkness or full sunlight. At the low price, every student or amateur wind or string player can afford to carry one everywhere.

    There is no provision for "stretch" in piano tuning, and no alternate temperaments. Not loud enough to tune a large ensemble by itself.

    5.0 out of 5 stars excellent value, works great for acoustic guitar & bass, size of a credit card
    Reviewed in the United States on April 5, 2014
    Style: CA-1 Chromatic TunerVerified Purchase
    The best part of this tuner is that I can set it on the coffee table, and it hears my guitar just fine. This chromatic tuner is a major improvement over the analog tuner I was using to tune my acoustic guitar & acoustic bass. The pitch is recognized automatically by the Korg CA1. The digital needle stays exactly at the spot that the instrument is tuned to; when you tune up or down, the needle moves very precisely without jumping. The CA1 is about the size of a credit card but thicker. It's made in Vietnam and looks well made. Hopefully it will be durable.

    This is really a miracle device compared to my old Matrix analog tuner, which wouldn't recognize half the notes at all, the needle just wouldn't move and then jump violently, and it had to be touching the soundboard just to pick up anything. I've just been using the mic on the CA1 and haven't tried the line-in jack for guitar chords.

    5.0 out of 5 stars Glad to have this tuner
    Reviewed in the United States on November 11, 2016
    Style: CA-1 Chromatic TunerVerified Purchase
    Glad to have this tuner. My other one stopped working on me.
    As a tuner should, this helps me tune my guitar by telling me what note I'm closest to, and if I'm sharp flat or perfect. It really helps me since I know what note the strings should be. I am careful not to go too high so I don't pop a string. I haven't popped a string in ages since the first time.
    This really helps me to make sure I'm always in tune before having a jam session, and in between to make sure I'm still in tune. It fits in my guitar case, and the batteries last a while...That's probably why my other one stopped working though. They lasted so long they sprung a leak. I'd recommend checking your batteries every once in a while to make sure they aren't leaking, because that could damage your device.

    Overall, it's really consistent and does what it needs to do. I have no issues with it.

    3.0 out of 5 stars Inexpensive, works very well, wish it had a power LED and/or a backlight
    Reviewed in the United States on September 23, 2016
    Style: CA-1 Chromatic TunerVerified Purchase
    I record music in a homemade studio and I was getting annoyed with having to hook up my inline Boss tuner with every instrument change. I wanted something that would work with an acoustic, an electric, and a bass (plus vocals). There aren't a whole lot of options on Amazon, this seemed like the popular one. I didn't want a clip on because I haven't had the best of luck with them.

    This unit, in terms of accuracy, is AWESOME. It's really sensitive, you'll be perfectly in tune if you mess with your tuners long enough to satisfy this tuner.

    My complains with it: no backlight, so it can be difficult to see the "needle". HOWEVER, the unit has red/green LEDs that make this pretty easy enough in the dark. My other complaint is that there isn't a power LED to indicate the unit is on. I'm pretty sure I'm going to end up burning through batteries because I leave it on, can't see the needle on the screen because it can be dim unless looking right at it.

    Overall, I like it a lot and would recommend it. But it requires some babysitting.

    Works very well, really precise and easy to use. Small enough that you can easily carry it with you in your pocket.
    Update Nov. 2016: Have been using it for about half a year now. This is a very reliable, handy tuner. Even though it is digital, it shows an analog needle-type meter that allows for very precise tuning. It shows, for instance, when a string is going a bit higher after having been plucked (often an indicator that you need a new string). I have also seen people using it for brass and woodwinds, and it works just as well. A great little inexpensive toy that every musician should carry around.

    The delivery was in time. The product works fine. But when I opened the package, the product had a part missing: the plastic stand. The user's manual clearly shows there's a "tilt slit" to insert the stand, but unfortunately no stand was included in the package. Surprisingly, only after 2 days of delivery, the return and replace window was closed. Anyway, I'm still happy that the instrument functions properly, and meets my purpose.
