Headstock micro tuner for violins and violas from NS Micro series that features an easy-to-read, tri-colour reversible backlit LCD screen and visual metronome in an attractive compact design. It is equipped with a non-marring, lever-lock clamp that holds the tuner securely to the instrument while allowing easy application and removal, a built-in piezo transducer that picks up instrument’s vibration rather than sound and therefore provides more precise tuning. It also provides wide calibration range from 410 Hz to 480 Hz.
