Professional musicians demand precision, and the Korg OT-120 orchestral tuner provides exactly that with its sophisticated dual-display system. This versatile tuner offers both analogue needle-type indication and digital readouts, giving you complete control over how you monitor your instrument's pitch accuracy. The needle display clearly shows frequency deviation from your target note, whilst the customisable needle response speed lets you match your personal tuning preferences.
Two distinct tuning modes cater to different playing styles and situations. Auto mode intelligently detects the pitch of notes as you play them, making quick tune-ups effortless during practice or performance breaks. For traditionalists who prefer manual tuning, simply set the device to your desired note and fine-tune to achieve perfect pitch the conventional way.
The comprehensive LCD screen keeps all essential information at your fingertips, displaying battery level, sound output level, calibration settings, key, and note data simultaneously. With over 100 hours of operation from just two AAA batteries, this tuner is built for touring musicians who need reliable performance night after night.
