I’ve had one of these for about a year now. It’s always perplexing and beguiling whenever I play it. It sounds fantastic, and never seems to do the same thing twice, even if you try. I’ve been trying to NOT learn how it works - I like having the knobs be kind of mysterious with this thing.
I originally planned on building one of these, and bought the kit. My plan was an unmarked unit - just a bunch of mismatched knobs on some kind of box. And I got it about half way done, but got distracted by other projects, and ended up buying a premade one, and ended up trading the unbuilt kit away a few months ago.
