This is a VOX amPlug 3, which I purchased at a musical instrument store for around 7,000 yen. You can connect it to headphones or small speakers to enjoy guitar sounds at night, etc., with excellent sound quality. I've only used it a few times, so I think it's in good condition. However, it has been stored at home, so please refrain from purchasing if you are overly concerned about its condition. Thank you.
