I used this item for about a month after purchasing it used. There is a noticeable, unremovable scratch on the volume knob, and there are also a few other minor scratches. However, all switches and Bluetooth functionality worked without any problems. It has been initialized and comes with a USB cable (the cable is unused, so its functionality hasn't been confirmed), and the original box. The sound customization is very high, and even if you don't like the amp's original sound, if you're comfortable with sound design on your smartphone, you can likely get it close to your ideal sound. This is a key difference compared to other amp simulators like the Spark, and it was very good for practice. I hope someone who needs it will use it. Please understand that this is a used item.
