It offers precise pitch detection for a variety of instruments, built-in sound reference tones, and customizable calibration, all backed by a 3-year warrantyβ€”perfect for musicians demanding accuracy and versatility. ## Description Offers both tuner and metronome functions simultaneously or independently. Its large LCD-type needle delivers both the accuracy of an LCD and the excellent visibility of a needle indicator. It also has LED indicators that show pitch deviation or blink to indicate the tempo, making the TM-40 a highly visual tool. Provides quick and accurate coverage of a wide spectrum of notes and pitches for wind, string, keyboard, and most other instruments Excellent Functionality and a Wide Detection Range With a detection range of C1 (32.70 Hz) - C8 (4186.01 Hz), the TM-40 provides quick and accurate coverage of a wide spectrum of notes and pitches for wind, string, keyboard and most other instruments. Even low-pitched instruments with complex overtone structures are detected with the precision you expect from Korg. A built-in high-sensitivity mic allows acoustic instruments such as guitar and ukulele to be tuned easily and accurately, and the separately sold CM-100 contact mic can be used to send the vibrations directly to the tuner for even greater precision. Sound Out! In addition to the visual tuning guide provided by the meter, you can use the TM-40_s built-in speaker to produce a tuning reference pitch (Sound Out). Review: 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. Review: 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. ## Features - Scale: 12 note equal temperament - Detection Range*: C1 (32.70Hz) - C8 (4186.01Hz) for a sine wave - Reference Tone: C4 (261.63Hz) C5 (523.25Hz) One octave or A Bb - Tuning Modes: Meter mode (AUTO), Sound Out mode (MANUAL) - Calibration Range: A4 = 410Hz 480Hz ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000AAGM0M | | Best Sellers Rank | #43,556 in Musical Instruments ( See Top 100 in Musical Instruments ) #102 in Metronomes | | Brand | KORG | | Connector Type | DC input jack | | Customer Reviews | 4.6 out of 5 stars 661 Reviews | | Global Trade Identification Number | 04959112033627 | | Item Weight | 3.84 ounces | | Manufacturer | Korg USA Inc. | | Mfr Part Number | TM-40 | | Model Number | KOR TM40 | | Number of Items | 1 | | Tuner Technology | Digital | | Tuner Type | Digital | | UPC | 884088500528 805232066523 603384033628 | | Unit Count | 1 Count | | Warranty Description | 3 year parts and labor. | ## Images ![Korg TM40 Large Display Digital Tuner and Metronome - Image 1](https://m.media-amazon.com/images/I/71lHoECZYSL.jpg) ![Korg TM40 Large Display Digital Tuner and Metronome - Image 2](https://m.media-amazon.com/images/I/51PNA9SiJJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not the best tuner or metronome, but perhaps the best for the price. *by P***M on November 11, 2006* 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.

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. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/89143700-korg-tm40-large-display-digital-tuner-and-metronome](https://www.desertcart.be/products/89143700-korg-tm40-large-display-digital-tuner-and-metronome) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-23*
