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!

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.

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.

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.

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.

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.

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.

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.
