http://neuraldsp.com/products/darkglass-ultra-plugins/ I own the hardware B7K Ultra. I did a quick test today (I didn't save any audio examples, I know, what kind of shit is that?) and the plugin is spot on. There's also a Vintage Deluxe Ultra modeled here. so it's two plugins in one. They're rather CPU intensive, and the trial at least requires iLok. 99 Euro, which comes to about $120 American. Tempted to buy, myself, for the Vintage Deluxe emulation, which I really like. Through this, I literally just found out about the B7K Ultra v2. Is there some kind of exchange program for the updated hardware? lol. I've had the Ultra less than a year and already a new version is out.
