Nature Sound 40000pre. I've been using this on my effects board for about three years. I'm selling it because I'm significantly upgrading my sound system. There's a bit of paint chipping on the front, and there are Velcro marks on the back, but it works perfectly fine. I'm honestly hesitant to sell it, so I might cancel the listing. Please be aware of this possibility. It will be shipped via Kuroneko Yamato. - Model Name: 40000pre - Color: Black - Included: Box, Instruction Manual - Material: Metal - Number of Knobs: 1 - Number of Switches: 1
