## Description

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: 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.
Review: 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 desertcart, 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.

### ⭐⭐⭐⭐ Quality tuner/metronome for the price
*by H***5 on November 20, 2009*

This digital tuner and metronome is a decent little device. The tuner features are basically what I would have expected and are pretty standard. You can use it to play a straight tone, use a 1/4" input jack to get digital tuning feedback, or you can use the built-in microphone to get digital tuning feedback from the visual display panel. All very standard and functional, but I have to say that my old Boss digital effects pedal for my bass has a much better tuner. The metronome features, which are what I purchased the device for, are simple but functional. The metronome has 13 beat patterns that cover 0-7 beats per measure as well as doublets, triplets, triplets with center beats omitted, quadruplets, and quadruplets with center beats omitted. Tempo controls allow a range of 40 to 208 BPM, but the BPM intervals are not smooth. When changing tempos you'll jump from 40 to 42 to 44 at the low end of things, jump by 4's and 6's in the middle ranges, and at the high end the tempo controls tend to jump in 8's (208, 200, 192, 184, etc). I really would have preferred finer tuned control, but I understand the limitation to these devices. The beats that you get are steady and acceptable, definitely good enough to get a good feel of a beat. Buttons are clearly marked I haven't been able to get a good measure of the battery life on the device, but it uses two AAA batteries and has an auto shut-off feature. Overall, the interface is simple and functional. I was able to use all of the features without having to dig through the manual. I wish that the device felt a bit heavier and durable, but I still think that it will probably be able to survive in my gig bag for at least several years. I have used nicer metronomes and tuners before, but as a combined product for the price, this is a good choice for the traveling musician. It will get the job done, but if someone swipes it or you lose it the replacement cost isn't really an issue.
