YAMAHA Chromatic Tuner TD-12 by Yamaha. It features a pitch selection function and an LCD display for precise tuning. It also includes a memory backup function, an auto power-off function (approx. 20 minutes), and a sound generation function. Furthermore, it has guide marks for pure major thirds and pure minor thirds, which are convenient for creating the sound of pure tuning. The display methods are LCD and LED indicators. It has a tilt slit. I have confirmed that the power turns on and the needle moves as shown in image 9 after inserting batteries. The items in the photos are all that are included. I have cleaned the item thoroughly before listing it. While there are no noticeable scratches, there may be some small, unavoidable dirt from use. There are no pets or smokers in the household. However, individual perceptions may vary. Please understand that this is a used item stored by an individual, so please check the images and refrain from purchasing if you are sensitive to details or are in a hurry or have unreasonable requests. Also, although I inspect all items, I am an amateur, so there may be oversights. I do not have expert knowledge, so please purchase only if you understand that this is a used item and that the current condition takes precedence.
