This is the board size for the RNDI. For guitarists and bassists who connect directly to DI, etc. I think you'll notice the difference even with passive use. I've assembled it on a board, so Velcro is attached. Only sound output tests have been performed. There are no major scratches. Photos will be added. The original box is included. The rubber feet that were removed to attach the Velcro are also included. User registration has not been completed. Thank you.
