This water-repellant dust cover is made from rugged Ballistic Cordura to safeguard your gear from dust, spills, and other studio (and stage) mishaps, while the ultra-soft interior remains gentle against your synth. Custom-fit with room to accommodate patch cabling and rear I/O panel access. Adjustable Velcro straps ensure your dust cover fits snug and stays in place. This dust cover is a perfect fit for 60HP Moog semi-modular synthesizers mounted in a Moog 3-Tier or 2-Tier Rack, [depending on the option you choose.]
