Clip-on tuner for musical instruments with a full-color LCD. Features tuner, metronome, and tone generator functions. The tuner allows for calibration up and down by 10Hz. USB-C rechargeable. Charging cable included. Almost unused, only tested for photos and functionality. Purchased December 2025. Manual is in English only, but there are few buttons, and operation is limited to long and short presses, so there shouldn't be any problems. Shipped via Takkyubin Compact.
