Tuner, pickup microphone, and metronome: This compact 3-in-1 device is a versatile item that can be used with various instruments. The "arm clip" mechanism, which rises from the clip part, allows you to freely adjust the display angle for easy viewing. It has a built-in microphone, so you can tune without attaching it to your instrument. Digital cent display shows the pitch deviation numerically, enabling more precise tuning. Used item. Please consider this item if you understand that it is a used item. I am not good at dealing with those who are overly sensitive, so please understand.
