Precise Tuning

The OT-120 uses a high-precision needle-type meter for accurate pitch discrepancy measurement. The speed at which the needle responds to the input can be changed to fast, medium or slow to match your tuning preference.

In Manual mode the needle movement is shown in a range of plus or minus 50 cents, letting you view the tuning discrepancy over a wide range. In addition to the needle meter, the LEDs located below the meter also indicate pitch deviation or a perfect match, making precise tuning easy even in dim locations.
