Crate TX50D 50W guitar amplifier. Features: Independent controls for 2 inputs: microphone and instrument Built-in rechargeable battery Ideal for camping and street performances The AC adapter for charging is missing, so charging and operation cannot be confirmed. Operation cannot be confirmed because the battery is unusable, but I will sell it to someone who can use it after replacing or repairing the battery. Operation has not been confirmed. I do not have any knowledge of amplifiers, guitars, or basses. I have absolutely no knowledge, so I cannot answer any questions. Therefore, I am selling it as junk. It is not junk because it is broken, but because I lack knowledge. I don't know if it's actually broken. Everything in the pictures is included. How about it for someone who can repair it? Since it is a used item, there are stains and scratches. Please understand that I cannot completely clean it. This is a junk item. Please check the pictures and purchase only if you are satisfied. Please refrain from purchasing if you are a perfectionist. 11020
