This is a Roland CUBE-20XL BASS bass amplifier. I bought it used, but it's in beautiful condition because neither the previous owner nor I used it much. Everything works perfectly. No crackling or noise. It's compact yet has excellent sound and features. I'm selling it to organize my equipment because I bought a high-output amplifier. Although it is in beautiful condition, it is a used item, so please refrain from purchasing if you are looking for a new item or are sensitive to condition. It's a popular product, so don't miss out!
