First of all, everything FabFilter has the best GUI in my opinion and seeing a reverb with a FabFiltered layout is very appealing to me. It sounds really nice in the video and considering my list of reverbs (I must add the Tsar-1R to that) this looks like a big step up ;)
The Decay Rate EQ looks awesome! That's probably what I am most curious about - besides the effect it self of course. I can't wait to demo this thing.
It's just a reverb, how interesting can it be, but considering what I have, this really intrigues me ;)
