I remember Paul Davids' video where he played inside a nuclear power plant in Austria, and the reverb inside of that was incredible.
Already have a few reverbs:
I haven't felt much of a need to buy any more of them, ever since I picked up the Sloer.
Delays, on the other hand, are a different story :-).
I'd like to own one of these Nucleo pedals, but it's not too high on my list, just yet.
Will probably wait a while, to see how I feel about it maybe six months or so down the road.
