Korg OT120

Orchestral TunerKorg tuners are since a while widely used by many musicians, which is a reason enough for Korg to expand the program.

With its wide range extending from A0 to C8, the OT-120 lets you quickly tune any type of brass band or orchestral instrument – wind, string or keyboard.

The OT-120 also provides a wide range of calibration to support concert pitches in a range of A4=349-499 Hz (1 Hz steps). A high-precision needle-type meter accurately indicates any pitch discrepancy. The speed at which the needle responds to the input can be changed over a range of three steps. Best quality for supporters of the classic display.

  • Different tuning modes (12 equal tempered, Pythagorean, Werckmeister III, Vallotti, Mean Tone Eb, Kirnberger III, Young, Mean Tone D#, Kellner)
  • Large display
  • Tuning range A0 to C8
  • Reference Tone C2 through C7
  • Calibration: 349-499 Hz
  • Easy handling
  • Power supply not included

My favourite tuner!!!
TrEr, 28.10.2020
This is my favorite studio/workshop tuner by far! Excellent for doing setups/intonation. The needle is much easier to work with than any LED or strobe tuners. The various modes makes it really flexible too. It works great both with mic and jack and responds very nicely to all instruments I've tried.

Of course this isn't a stomp box so it's not really suitable for a pedal board but for studio use or doing setups in a guitar workshop it is absolutely superb.

I've tried pretty much all of the most popular tuners and this one makes my job so much easier than the rest. Unlike certain hi-end strobe tuners it isn't TOO precise, just perfect.

The only con would be the display. The display fades out completely when looking at it from certain angles. It's not a huge problem but can be slightly annoying, particularly when using the tilt back legs and looking at the tuner from above. I really wish they had used a better display.

Apart from the display I have no complaints. I can honestly say I've never been happier with a tuner and it's not even particularly expensive.

Highly recommended!

Could have been better
Milberry, 18.03.2021
I purchased this orchestral tuner to try tuning my upright piano. This Korg seemed to be the only option as I could find no alternative products in this class.
The reality is that the tuner presumably does its job reasonably well, although it does not detect sounds in the far bass and far treble octaves of the piano.
Also, I was quite utterly disappointed by the build quality of the device. It is made of cheap plastic and is very, very far from feeling "solid". All the switches and buttons are very wobbly and unpleasant to touch. Overall, it feels so much different from the sturdy construction of Korg's guitar tuner pedals.
Frankly speaking, it is a big disappointment.

Does not work for piano
15.06.2014
I bought this tuner to use for tuning pianos. Korg claims that it has a detection range from 27-4186 Hz, which is completely untrue. The OT120 does NOT detect notes of neither the bottom two or top two octaves of a standard upright piano. I've tried to use it with 5 different pianos and it always has this problem.
So, don't buy it if you need to tune notes at 80 Hz or lower, or at 1500 Hz or higher.
But between (approximately) 80-1500 Hz, it works fine

It's a good product. I personally know professional tuners that use this exact model.
