I purchased this item and used it a few times indoors at home, just to test the sound. I'm selling it because I haven't used it since putting it back in the box. When I bought it, there was a mark on the rubber surface that looked like it was made by a black magic marker. Please check the mark in [Photo 10]. I used it with a separately sold dedicated board, which I will include. I did not attach the effector to the board with Velcro. *The dedicated board has a 1cm riser attached to it with Velcro. ◯Included: Dedicated board / PCI Japan warranty (from the import agent) / Instruction manual A famous song used by Tsuneta of King Gnu Thank you for your understanding!
