Thank you for viewing. I am selling an Inner Bamboo B-II base preamplifier. Includes box and instruction manual. Purchased new in 2023. Functionality confirmed by the manufacturer in 2025. Used as my main equipment until recently, and there are no operational issues. There are some minor scratches and dirt from use, but they are not noticeable. Please check the condition in the photos. Please consider that this is a used item before purchasing.
