This is a digital wireless system compatible with guitars and basses. It allows you to move freely on stage without cables, while also achieving high-quality sound equivalent to wired systems. It's a popular model that is highly regarded by professional musicians. 【Condition】 Used only once in a live performance a few years ago, and has been stored at home since then. The batteries were removed and stored separately after use. The batteries had deteriorated and were disposed of, so batteries are not included.
