※ No price negotiations. ※ Receipts will not be issued. I have confirmed normal operation, but there are the following minor issues: ・The lower-left ▼ button has slightly poor contact. It may not respond when pressed lightly. It is not crushed. ・The center knob originally had a rubber cap, but it has peeled off. This does not affect operation. ・The original adapter is broken. Currently, it is powered by a compatible adapter made by FREE THE TONE. Both will be included when shipped. ・Occasionally, the sound would stop. It would recover by restarting the power. It was presumed to be internal processing, so I tried initializing it, and it improved. After initialization, I tested it for about an hour, and the symptom did not occur. However, I cannot guarantee that the symptom will not occur in the future. If you are looking for perfection, I recommend having it inspected at a musical instrument store after purchase. ・There are many scratches, although there are no noticeable marks. Please understand that this is a used item before purchasing.
