Not the best tuner or metronome, but perhaps the best for the price.
I've always had difficulty finding tuners with adequate response, and this one was actually a downgrade from the OT-12 (my favourite pocket-sized tuner), but it surprised me by working better than any previous combined metronome-tuner while not costing much more. The response rate is not adjustable, but sits at about a medium (there has to be at least a second of sustenance, but not more than two if you're steady). The precision is about as good as most will ever need, although it's dubiously delineated between -3 and +3 cents. The rest of the spectrum to fifty is clear-cut (it is fully digital, for better or for worse). The accuracy is also as good as could be asked for at its price-range, but not great - you may want to let it cycle a couple times for the more troublesome notes or if you're of the end-inward school of tuning. There are no temperament settings, but very few musicians will miss that option. There is an input for contact mics, though the impedance choice is commodity. There is a mono-out as well, if memory serves (as opposed to stereo - monochannel is standard). Overall, the tuner is better than any budget-priced combination product I've ever seen (esp. the increasingly popular but rarely satisfactory Sabine MetroTune). The metronome function is likewise fairly good. 7 beat options and some standard subdivision patterns, the usually discrete-option tempo selection (hence, precision not the most flexible, but not worse than similar combination products). Accuracy is fair enough but not great. It fits the r10 error rating given by the factory, as opposed to the r15/r18 of the very cheapest units or the excellent r2/r1 of purposeful objects like the Dr. Beat. Experienced musicians may wish to trust their instincts after getting the right idea from the metronome. The error is scalar, it will be less troublesome at lower tempos. The state of affairs in small and cheap timing devices is surprisingly bad, but this is certainly not the worst (for that, see Sabine, again). Unlike most similar products that I've seen, the two primary functions can be used simultaneously (tuner and metronome). I don't use this aspect much but some customers might really like that (esp. instruments that will draw a faster response from the tuning function). I cannot yet attest to the average battery life of the thing, except to say that it's at least not bad.

fabulous
this metronome is just fabulous for the price. I actually wanted a tuner specifically but realized I could get a portable metronome in that tuner for an extra $10. So I bought this model with both. The tuner is pretty cool in that it will tell you what note is being played and a green light comes on as long as the pitch is within the acceptable range. I think the tuner may be hyper-sensitive as I can never get both my 2nd octave C and the C above that in tune at the same time on my flute. I have not experimented at all with the calibration function, though. Still, I'm happy and find it to have improved my duet practice. The metronome is great too. It's loud enough that we can both hear it during duet practice. I figured out both the metronome and tuner functions without having to read the manual so I think their operation is fairly obvious. What I love is that you can turn on just the tuner or turn on just the metronome. You do not turn both on automatically. I love the small, portable size too. And I love the decent price. Overall, I am very happy with this purchase.

Good tuner.
This is a very good tuner that performs the basic functions of individual string tuning on the guitar well. For example, if you set the tuner (meter mode) for E and then play the E sting, the digital meter will give you a clear indication of how near or far you are from that note. There are also lights that work in conjunction with the meter to indicate if the note is flat, dead center or sharp. Also, you can set the tuner for flats and sharps and when you are trying to tune for that it will give you that same hi/lo/dead center indication with the digital meter and the lights. One of the reasons that I chose this device over others is that it does have some capability to perform "cents" tuning. I honestly don't understand all of that yet but have done some reading on it and will hopefully be able to use it someday for some songs. I really like the metronome function and how adjustable it is. I'm a beginning guitarist and smooth chord transitions can be frustrating. Using the metronome, it allows me to feel less stress when trying to finger and play various chords because the clicks can be slowed down. That gives me a psychology boost because I'm able to accurately play a chord and then set up for the next one before the 4 beat cycle gets back to the beginning. As my speed and accuracy improve, I can speed up the metronome, setting a higher standard for myself. Though I feel that this is a good product and worth your money, I only gave it 4 stars. The reason is the tone generator or sound out function. To me, when I select E, A, D, G, B, or E, the tones don't actually sound like the notes I want to tune to. If you want to hear what one or all of the sting notes sound like on the guitar, there are quite a few nice tools on the Internet that will do that for you. One I like can be found at [...]. Also, the instruction sheet that comes with this device seems a bit abbreviated to me. I have never had any formal music training and that may be why I feel the instruction sheet is lacking. Mostly a lack of understanding on my part. Would I recommend the Korg TM-40 to a friend or to you? Yes. There a couple of things that I don't like about this product but all things considered I feel as if I got my money's worth.

Perfect!
This metronome/tuner is perfect for guitar. I have only tuned by plugging in my electric guitar. It was very responsive. by this I mean that you dont have to turn the knob, then wait a moment for the screen to catch up. The tuner seems very accurate. I tuned my guitar with this tuner, used my 1/4" to USB converter and plugged it into my MacBook Pro. It was very close on every string, but I have never been too sure about the quality of the Garage Band tuner. The Garage Band tuner flitters back and forth from tuned to low or high, yet the needle on the Korg is very steady. This makes it much easier to get it perfect by the tuner. I would like to believe that the Korg is more accurate than my computer, but I guess I have nothing to base that on. If it isn't, it at least it's way easier to use. Plug it in, turn it on, end of story. It detects if something is plugged in and uses it instead of the microphone automagically. The deal where you tune it to the pitch it plays kind of has an annoying sound. I am not good with tuning that way, so I don't use it. Plus, why would you use it if you have a real tuner in your same hand. The only complaint I have, is I wish you could tell it which string you want to tune, instead of only having it tell you what note is being played. The metronome is also very good. It has more features than I knew a metronome could have, but I know nothing about metronomes. I love the feature where you tap the button twice and it automagicaly metronomes at the rate you hit the button. They should use this same technology in windshield wiper blades. I have wished this for a long time, even before I got this tuner. Just saying. The thing beeps instead of clicks. If you really want clicks, don't get this. Its NBD for me. Both parts can be used at the same time. Never used both at the same time, but it's good to know. The buttons and features of this thing are not completely obvious. Just read the page it gives you. As us nerds say, RTFM.

The only metronome/tuner at a great price
This is the best metronome/tuner I have owned. When I was browsing through all the metronomes at Amazon, all I saw was products that look like iPods, birth control containers, and huge watches. However, when I saw this metronome, it was screaming at me to buy. When I saw that there was only one left in stock, I just had to order it. Pros: This metronome is the most aesthetic out of the rest. The color scheme is perfect and the buttons are easy to press. You can even output the metronome and reference sounds. The metronome is loud and the display is the very user-friendly and even has a stand. The tuner function is AMAZING and fun. It can sense if your voice (or other instrument) is off tune and if you are singing the correct note. You can even input a mic or instrument via 1/4" cable for tuning. When I started using the tuner I had so much fun and learned at the same time. I am also an organist and choir member and I plan to use it to train the choir and myself in my church. Cons: This metronome is somewhat portable (lightweight but buttons are not recessed). I wish there was a sturdy case for it since buttons could be pressed in my bag. Some improvements: -A bluish backlit display (like in Camry '07) -Rubber feet Bottom Line: The best budget-priced metronome/tuner for choir, singers, and general instrument players.

Great usable tool.
This is my favorite metronome; I wore the first one out after 30 years of using it, dripping it, getting it wet accidentally etc! I own a music store and didn’t like the TM-50 that Korg replaced this TM-40 with nearly as well so I was simply delighted to find this still available. I think the casing is better quality than the newer TM-50 though they are both very easy to use. The metronome part has the flexibility and accuracy of a small Dr. Beat and the volume is good enough for students to hear simultaneously. The tuner part can be calibrated if you have to tune to a church organ or such. The tuner and metronome can be used independently. It takes AAA batteries that are easy to replace and which last a long time if you remember to turn it off when not in use. Korg products are top of the line.

Convenient and Reliable
A few years ago, my son's private lesson teacher suggested this, and it quickly became our favorite accessory for his case! The metronome is fantastic, and I love that you can easily tap into the tempo. He hasn't figured out how to increase or decrease the tempo by just one beat, but that's okay! The tuner is an excellent addition to have on the stand. He enjoys using the tuner and metronome together, even if it’s just on the 8th note subdivision. It's super versatile—you can set it quiet or crank it up when needed. Plus, it fits perfectly in the case for travel! I would recommend it!

Great, but the newer one is a whole lot better
A little backstory: I play alto saxophone in my high school band, and it was required that all band members have a tuner and metronome on hand for marching and performances. I went with this as all the upperclassmen recommended it. I have to say that they were right, this tuner does its job well at the price. It tunes precisely, the metronome is fairly accurate with a wide selection tempos and beats, has a kick-stand for use on flat surfaces, the built-in LEDs make it incredibly user-friendly, the sound is adequate in quiet rooms, and it offers simultaneous tuning and metronome functionality. With all that in mind, it does have a few flaws. For starters, when I need to hear the metronome while practicing in a room filled with 50 other students playing, the sound gets easily drowned out, which is understandable. However, when I plug in my headphones to hear the beat better, only one ear bud seems to work. However, my headphones seem to work fine when used with my iPod or laptop. Unsure if all of them are like this or it was just mine, but it makes it incredibly frustrating to practice in loud rooms. On top of that, the screen is nearly impossible to read in low light or at certain angles, there's no indication of low battery life (so if it runs out during a performance, you're on your own), and it is easily dinged or scratched up in a backpack or instrument case. Now, here's the kicker: a few days after I received my tuner, Korg came out with a new version, the Korg TM50BK Instrument Tuner and Metronome, Black , that my fellow freshmen bought instead. After test-running one of my friend's, I found that the newer model does everything mine did and more. Although there's still no battery indicator and is still easily scratched up, both headphones work when plugged in, the screen is back lit for easier reading (although I have no idea how that affects battery life), and its "tap tempo" option is really accurate and convenient. To make matters worse, it is a whole $10 cheaper. Although it's still a great little tuner and metronome, and that I think it will do fine if you are an aspiring musician or in a band, learn from my misery. A higher price doesn't always translate to better quality, and that is true in this case. Get the newer one and avoid these annoying idiosyncrasies.

Le deux en un
Partie accordeur : précis et efficace. Partie métronome : volume sonore juste suffisant, mesures à 2 temps, 3, 4,5,6,7 temps,croches, triolets, doubles croches. Ce n'est pas une boite à rythmes, uniquement les rythmes de base. Appareil léger, relativement résistant aux chocs, touches de fonctionnement rendant l'appareil très facile et rapide à utiliser, les deux fonctions métronome et accordeur peuvent fonctionner simultanément. En résumé, c'est un appareil de base bien conçu. Depuis l'achat en 2010, l'appareil fonctionne parfaitement. J'utilise une mini enceinte avec raccordement par cable jack 3,5 pour l'amplifier, métronome et générateur de son pour accorder un ensemble d'instruments.

An excellent piece of kit
Don't be fooled by the price, this tuner/metronome is the business! Compact, efficient and easy to use... well done Korg, another winner! There really isn't much to add here, the tuner is fast and accurate both in direct input and mic modes, although I'll probably only use this one with direct input since I use a clip-on tuner with my acoustic guitars. The metronome on the other hand is incredibly useful as an acoustic aid and I'm sure will prove to be invaluable. Very easy to set and use and my playing is already benefiting from being more disciplined. As I said in the title - this Korg Tuner & Metronome is an excellent piece of kit.

Zwei super Geräte in einem
Schon länger benutze ich das Korg Stimmgerät - nachdem meine Stimmgabel auf Grund eines fast nicht sichtbaren Risses immer tiefer geworden war - und bin als Berufsmusikerin, Geigerin, damit äußerst zufrieden. Das Stimmgerät von Korg war eine Empfehlung eines Harfinisten. Zusätzlich schleppte ich immer ein Metronom mit mir herum, das Korg Metronom ist aber ziemlich groß und schwer. Nun besitze ich dieses Kombination von Stimmgerät und Metronom, - und kann es sogar in dem Fach im Geigenkasten verstauen, weil es wunderbar klein und leicht ist. - Stimmgerät: äußerst genau, der Zeiger flattert nicht so stark wie bei anderen Geräten, bei denen es dann schwer ist zu erkennen, wann es sauber ist. Natürlich schwingt die Saite nicht so ganz rein, zumal wenn sie nicht mehr so ganz neu ist, und dadurch ist es nicht ganz leicht eine genaue "Antwort" zu bekommen. Am Besten mit möglichst gleichmäßiger Strichgeschwindigkeit spielen, dann zeigt der Zeiger sehr eindeutig die Stimmung an. Man kann problemlos mit den Tasten "calib" die gewünschte Herz-zahl einstellen - in deutschen Orchestern wird mit 443 Herz gestimmt. Es gibt noch die Möglichkeit der Tonausgabe, ich selber mag diese Art von Dröte nicht so gerne um danach zu stimmen, aber das ist Geschmacksache, und mancher tut sich damit vielleicht leichter als mit der optischen Anzeige. - Metronom: es ist ausreichend laut, wenn ich mir auch noch ein wenig mehr Lautstärke wünschen würde, ist die Geige doch mit 90db am Ohr sehr laut. Aber es ist durchaus ausreichend wenn man es nicht für Ensembles verwendet und sehr nah plaziert. Gleichmäßigkeit ist eigentlich eine Selbstverständlichkeit und somit fast nicht erwähnenswürdig. Der akkustische Ton wird durch eine optische Anzeige unterstützt, ich selber mag das nicht, aber vielleicht gibt es Musiker, die damit zurecht kommen. Verschiedene Taktarten sind einzustellen. Außerdem kann man über die Tap-funktion ein Tempo eingeben und die Metronomzahl ablesen. Ich nutze das zB wenn ich eine CD höre und wissen möchte wie schnell es gespielt wird. Dann kann man mithören und im Takt eintappen und bekommt die Geschwindigkeit angezeigt. Ich stelle das Gerät meistens vor die Noten auf den Notenständer, es ist ausreichend flach um das machen zu können, das ist praktisch, weil man dann beim Üben schnell die Tempoeingabe verändern kann. Oft übt man aber ohne Notenständer, einfach nur Technik...dann kann man das Gerät mit einem ausstellbaren Füßchen auch auf einen Tisch...stellen und muss sich nicht verrenken um die Anzeige eines liegenden Gerätes beim Spielen zu sehen. Ich bin von der Qualität und Funktionalität begeistert, es ist zu meinem ständigen Begleiter geworden. Wie gesagt, nur die Lautstärke könnte besser sein. Deshalb klare Empfehlung.

Very good
Being new to guitars, it's difficult to review this as I don't have any experience or alternative items to use as comparisons. I've had the tuner/metronome for a few weeks now and it seems very good. Both the tuning and metronome functions work as I would expect. Tuner works via an in built microphone or via the socket on the side if you wish to plug a guitar or other cabled instrument in and it is chromatic to handle other tunings you might want to use. You can use either the tuner or metronome separately or both at the same time but I've been mainly using the tuner. The LCD screen is clear but cannot be back lit but it's easy to use and has flashing lights at the top for the metronome and tuning which allow it to be used in darker situations where seeing the screen may be difficult. The metronome I've used less but has plenty settings for different tempos and rhythms and it has a tap function letting you tap in a tempo which it will then recognise. It also has a volume control and headphone socket. I'm happy with it, and it seems a good item for the price.
