OT-120 Chromatic Orchestral Tuner description:

Tune string and wind instruments in a flash with the Korg OT-120, a tuner that combines the accuracy of needle-type meters with superior functionality, wide tuning range and a new, sleek vertical design.

The Korg OT-120 chromatic tuner is intended for orchestral instruments, packing precise performance and sophisticated functionality in a vertical design that's easy to hold and operate. The 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, 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 unit stand by itself. A sophisticated silver aluminum panel contributes to the Korg OT-120's sleek, new look.

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). A durable, suede-tone soft case is included.

Korg OT-120 main features include:

  • Chromatic tuner with a wide 8 octave detection range that supports band and orchestra instruments.
  • Dual display provides both a needle-type meter and an LCD for excellent visibility.
  • Sound Back (Patented: Patent pending) mode plays a reference pitch for the note that's closest to the input pitch. The meter indicates the discrepancy between the input and the correct pitch.
  • Multiple Temperaments support historical tunings.
  • Transpose mode is convenient for wind instruments.
  • Choose from three levels of needle response speed (slow, medium and fast).
  • Both auto and manual tuning modes are provided.
  • Built-in reference tone plays in a five octave range.
  • Broad range of calibration (349 Hz--499 Hz).
  • Built-in mic supports acoustic instruments.
  • Use with the optional CM-100 Contact Mic for accurate tuning in noisy environments.
  • Energy-saving design for long battery life (approximately 100 hours).
  • Durable soft case included.

Customer Reviews


The tuner is smaller than I expected. Almost exactly the size of a pack of cards. I like that.

The backlit screen goes yellow when the side switch is operated. Its very well packed with a durable carry case. The right side button operates the temperaments. The manual is like a folded paper map covering the main languages. Tiny writing. You can do a quick test by whistling notes at it. Layout and operation all seems logical and sensible. I have read lots of good reviews. The bad one did not know how to tune the central piano octave and then use that octave to complete the tuning.

Looking forward to tuning my guitar with new frets and Kirnberger 111. Far out man!
