Due to circumstances, this item will be on sale until mid-November. If it doesn't sell, I plan to have a store buy it. This is the Vivie CLIONE Professional booster/equalizer. It can be used as both a booster and an equalizer, expanding the range of sound creation. There are no noticeable scratches or stains, and it works well.
