The RC-505MK2 relies heavily on its surface pads to record, play and loop songs. Anything that is designed to be compressed, moved or rotated is prone to damage from dust, spills and impacts. That's why they created the Decksaver Boss 505-MK2 cover. Designed and manufactured to fit the contours of this exciting unit perfectly. They went through years of development to be able to create the perfect cover to protect the RC-505MK2. Super durable polycarbonate covers fit like a shell and are characterized by extreme durability and the highest degree of protection. Due to the small size of the unit, they have specially created a cover so that it easily fits into your backpack. No matter where you are, Decksaver will protect your 505-MK2.
