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