   "description" : "A pretty simple Dub echo, approximating something like the [Space Echo](https://secure.wikimedia.org/wikipedia/en/wiki/Space_Echo) made popular by King Tubby, Scientist, Lee Perry, et al. Built around the Feedback Quark, though I'm not really leaning on the functionality it provides over a simple LocalOut-based feedback path."
