Thank you for viewing. [Product Condition] New, Unused *Opened only for product photography and inspection. *The box has a slight crease (see the last two photos), but there are no scratches or damage to the product itself. [Features] Dual function that allows the tuner and metronome to be used simultaneously. An item that supports the improvement of pitch and tempo to maximize the appeal of playing. The tuner and metronome can be displayed simultaneously on a large LCD with 2-stage backlight. You can practice using the metronome while checking the correct pitch. Includes various modes to support practice: "Sound Back," "Track," and "Focus." [Tuner] In addition to basic usage, you can also check the pitch while listening to the sound in the sound mode, which oscillates a reference tone of 3 octaves. Includes marks indicating pure major and minor thirds. [Metronome] Equipped with 0-9 beats and 5 rhythm variations to make beats and rhythms easier to understand. The tap function, which measures and displays the tempo, allows you to quickly set your preferred tempo. [Functions to Support Practice] ◇ Sound Back Mode A function that detects the sound played by the player and returns the correct pitch from the tuner. By comparing the returned sound, you can cultivate your "listening ability" and "matching ability." ◇ Track Mode A function that displays the pitch fluctuation range after playing. Since you don't have to look at the screen while playing, you can practice aiming for a stable pitch without relying on the tuner. ◇ Focus Mode A function that changes the pitch display range from the usual ±50 cents to ±25 cents. Because the display scale becomes finer, you can grasp the pitch tendency in more detail. [Confirmation Items] The connection terminal for the tuner microphone is a mini-jack. The standard jack tuner devices that were previously sold cannot be used. Please purchase a mono mini-jack model for the separately sold tuner microphone. ◆ Compatible models: YAMAHA TM-40 / KORG CM-400 [Shipping Method] Yu-packet Post mini *May be changed immediately before shipping.
