Vertical Design and Superior Visibility
The Korg OT-120 chromatic band and orchestral tuner is intended for orchestral instruments, packing precise performance and sophisticated functionality in a vertical design that's easy to hold and operate. The Korg OT-120 features a dual-display, an easy-to-see needle-type indicator and a backlit LCD screen that shows the battery life, sound output level, calibration, as well as key and note name. Additional design features include a large dial that makes it easy to select the desired mode, soft-touch buttons and a rear-mounted stand that lets the band and orchestral tuner stand by itself. A sophisticated silver aluminum panel contributes to its sleek, new look.

Accurately Tune Orchestral Instruments Over a Wide Range
Since we developed the world's first meter-type tuner in 1975, the accuracy of Korg tuners has made them the choice of artists in all styles of music. With its wide tuning range extending from A0 to C8, the OT-120 lets you quickly tune any type of band instrument including, orchestra, wind, string, brass or piano. The Korg OT-120 also provides a wide range of calibration to support concert pitches in a range of 349-499 Hz (1 Hz steps).

Smooth and Precise Tuning
This band and orchestral tuner uses a high-precision needle-type meter to accurately indicate any pitch discrepancy. The speed at which the needle responds to the input can be changed over a range of three steps; you can choose fast, medium or slow speeds to match your tuning preference.

You can also choose from two tuning modes; Auto mode, which automatically detects the pitch of a single note you play on your instrument, or Manual mode, which lets you specify the desired note name. In Manual mode, the needle movement is shown in a range of 50 cents, letting you view the tuning discrepancy over a wide range. In addition to the excellent visibility unique to a needle-type meter, the LEDs located below the meter also indicate pitch deviation or a perfect match, making precise tuning easy even in dim locations.

Sound Back Mode for Tuning String or Wind Instruments
The OT-120 produces a reference tone in a five-octave range extending from C2 (65.41 Hz) to C7 (2093 Hz). You can switch the output level in two stages. The large speaker allows for more volume while not being obstructed even when using the stand, ensuring that the reference tone is clearly audible.

The OT-120 also provides Korg's proprietary Sound Back mode. This mode lets you connect an optional CM-100L contact microphone to the input jack, and automatically make the OT-120's speaker produce a reference tone for the note that is closest to the input pitch you play on your instrument. The meter will also indicate the input pitch, letting you tune using your eyes as well as your ears for greater accuracy--and also providing a great way to train your sense of pitch.

Support for Transposing Instruments and Historical Temperaments
For conveniently tuning any wind instrument, twelve types of transposing keys are provided in this band and orchestral tuner, including both sharps and flats. The Multi Temperament function provides eight presets that cover the most popular historical temperaments often used with period instruments. These are also ideal for checking unique temperaments used in classical music.

Long Battery Life
The OT-120 is designed for an extended battery life of approximately 100 hours when running on two AAA batteries. It can also be used with an AC adaptor (sold separately).

Soft Case Included
A durable, suede-tone soft case is included. Korg band and orchestral tuners purchased from a Korg USA authorized dealer now have a three year warranty.

The Korg OT-120 Chromatic Orchestral Tuner is awesome.
Amazon Customer
If you need accuracy to tune an instrument, discriminate between different temperaments and pitches this tuner does the best job!
Rodrigo Treviño
I use it for flute/piccolo, and notes that most tuners won't register because of the high range, this one picks up easily.

I purchased this for tuning my violin and piano, assuming it would do a great job on the violin (it does) but was wary of how it would work on the piano. I had been using a Peterson Virtual Stobe tuner for years, using standard piano-tuning techniques and equipment, and preferred tuning to a strobe rather than to a needle or LEDs. But battery leakage had put my VS out of commission. With the Peterson VS having its own imperfections, and a new one now running 3-4 times the cost of the Korg OT-120, I decided to give the Korg a try. (I also purchased the clip mike just in case its built-in mike balked at some of the overtones on my older piano.) I now use the Korg OT-120 regularly, not only to tune my piano and violin, but also as a practicing aid for the violin. It's very responsive and useful in verifying that I'm hitting pitch. After a few months of use I can say that the Korg OT-120 has exceeded my expectations for ease-of-use, value, and effectiveness for tuning my violin and piano, and for practice (strings). The tone generator is useful for ear training as well as for tuning. The display is smaller than I'm used to on the Peterson, but then again the Korg is much more portable. The clip microphone has come in handy for tuning some of the trickier strings at the lower and higher octaves, but I don't need to use it very often. Although I prefer the strobe for how it linearly visualizes pitch adjustment, it took less than half a tuning session to re-adapt to a needle/LED style display. Note: The Peterson has a larger number of tuning temperments than the Korg, so if you're tuning for early music make sure to review the temperments available on the Korg before buying. Nor can you store custom temperments on it.

Verified Purchase
The Korg OT-120 is a very competent and functional tuner at a reasonable price. It is very easy to use. Less than 15 minutes after first opening the package I had tuned one rank of my 61 note harpsichord to Werckmeister III at Baroque pitch, and I was immediately pleased with the results.

I had been using a Boss TU-12H, which can only do equal temperament and does not allow for changing of the base pitch. Aside from those limitations, I can now hear that it was also never very accurate. Even after meticulously tuning every string, I often found my instrument still sounded quite harsh. I always had trouble with the Boss TU-12H's needle going wild and never really settling in on a clear reading, so I often had to rely on my ear (which is still not very good), often resulting in an inconsistent tuning.

After tuning with the Korg OT-120, there was a significant improvement. I never realized my harpsichord (which is a budget model) could sound this good. The Korg OT-120's needle is much more stable, usually centering on a reading very quickly, though somewhat slowly for the lowest notes. I did have some trouble getting a response on the three or four highest notes on my keyboard, but on my instrument they are pretty quiet, so that is most likely the reason (rather than just the highness of the pitch itself). The display is good and easy to read considering the size, and I like that the back lighting can be turned on or off as you need it, to help conserve battery life. It's nice that it comes with a case, but it must be completely removed from the case to use it.

I purchased it with the optional CM-100L contact microphone, but found that there weren't a lot of places to connect it on my instrument that worked well, at least for all the notes.

Verified Purchase
I purchased the Korg OT-120 tuner after seeing several reviews of the product. For me, the price at Amazon is competitive with other retailers. I wanted to use this tuner for piano tuning. It has several features that I found helpful. First is the microphone pick-up that is on the back of the tuner is sensitive when placed near the strings and used in a quiet environment. Second, the needle dial is quite helpful in finding the correct pitch as well as the indicator lights for flats and sharps. I purchased the microphone, yet I really don't see that much more sensitivity using it. The lowest octave and the highest octave are not really picked up by the tuner so you will have to use your ear to get those scales tuned with the rest of your octaves. For me, this was a good investment for my money, I would buy the tuner again. I wish it came with an AC adaptor, you will have to purchase one as batteries will eventually drain down.

The response time is really fast and accuracy, My father use the tuner for percussion instruments, marimba, lira, xylophones, etc. The Tuner is for professionals, my father made instruments the tuners are using for industrial purposes, OT-120 is the best.

I have used two different units OT-120 and both tune fine (or display) the pitch center,
but both units display a too large pitch deviation if the note is off-center.
I just returned my second unit which I bought because I suspected the first unit being defect.
No, that is obviously a KORG systematic error.

Thanks God I own one old KORG MASTER TUNER, which operates much better than the new OT-120.
(All tuners work better if used with an external micro and a pre-amplifier)

If you want to measure the cents deviations of a tone, do not buy the KORG OT-120.

Testing the SEIKO SAT1100 soon.
