The OT-120 is a chromatic tuner intended for the orchestra,
packaging high performance and sophisticated functionality in a
vertical design that's easy to hold and operate. It features a
dual-display, an easy-to-see needle-type indicator and a backlit
LCD screen that shows the battery level, sound output level,
calibration, key and note name. Additional design features
include a large dial that makes it easy to select the desired
mode, finger-friendly buttons and a rear-mounted stand that lets
the unit stand by itself. A sophisticated silver aluminum panel
contributes to its sleek, new look.
