Please be sure to check before purchasing to prevent any problems. This item is being sold as-is. I have confirmed its operation with my adapter. * Item includes the main unit only. * Power on * Effect functionality * Switching * Wah and volume functionality have been confirmed. Other detailed functions have not been confirmed, so this item is being sold as-is. As this is a precision instrument, it will be shipped with waterproof measures and plenty of cushioning material. I would appreciate it if those who understand and agree with the above would purchase the item.
