Bass Compressor Inner Bamboo U-2. Early model with wooden panel. Includes a cleaning cloth for the panel and the original box. The cloth has some stains from use. There is some dullness on the metal plate, but this is due to aging. Works perfectly. I think it's in good condition, but there is one noticeable small white scratch on the back. If you've been looking for one, please consider it. inner bamboo sumo stomp
