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.

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.
