A classic digital metronome made by KORG. It has various functions such as a training mode to set the tempo, a change-up function that automatically changes the tempo at regular intervals, and a program mode that can save/output original patterns set by yourself up to 24 slots. I bought it new for practice and used it a few times at home, but I didn't have many opportunities to use it, so I decided to let it go after storing it for a while. Since it has been used little, there are no operational problems, and it is in a clean condition with few noticeable scratches or stains on the exterior, but there is some damage to the outer box and some yellowing of the buttons due to long-term storage. The LCD protective film is as it was when purchased. Please refer to the images. Also, please understand that this is a used device. The product will be wrapped in cushioning material and placed in the original outer box, and then the outer box will be wrapped in cushioning material and shipped in a cardboard box (or box).
