Even though the OP-1 has been around for a while, I’ve only become aware of it recently, and it is amazing.
It is also pretty expensive and spectacularly hard to get hold of (it used to be on sale on MoMA), which is sad–I’ve been spending a few of my evenings lately watching YouTube videos of what people can do with it (Red Means Recording has some amazing tracks made on it), and would love to get one for Xmas.
