Maxon don't mess around, so this purple piece of pizzaz packs plenty of punch. The guts of the circuits, as best as I can tell, is largely analog, so you're getting proper analog compression and whatnot. It sounds a lot more natural overall than other vintage multis we've had through, it's definitely got a thing.
