This is the compact enclosure version of the OKKO Diablo Overdrive. It's a version that was sold for a while, and I purchased it directly from a musical instrument store overseas. I've only used it a few times indoors, so it's in almost pristine condition. The accessories include the box, instruction manual, and everything else that came with it when I bought it. It's a discontinued version, and I think it's a model that's hard to find, so if you're interested, please consider it.
