Korg OT120

Orchestral Tuner

Korg 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

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

Works well so far.

Robert F. 353, 28.04.2014
Playing a 5 string, I wanted to find a tuner <£100 which would handle the lower frequencies, and had a good reputation.

Spot on, so far. It's picked up all the strings quickly and accurately (Tested this morning against online tuner/phone app/clip-on tuner/piano) and the features are useful and varied. The display is best viewed from within 5 feet, although the red lights indicating a 'lock' on the note are large and bright enough to be seen clearly from around 10 feet.

Only tiny niggle is the fact that it's a little bulky in-hand, though most of the time, most people probably won't be holding it when they use it.

The carrying pouch which is supplied with the tuner is pretty smart.

Happy with it.
