Ugh indeed. How about two SAD1024s, so you can keep the clock down?
It is ugh but another ugh.

One has to adapt the feedback terms accordingly.

Well, using a spring-reverb as resonator is certainly possible. Have you looked
at the Neural Agonizer? It's quite nice. I "just" need to finish it off. Really
down to interconnecting the last things. I have one of those sitting in a box
with two spring-reverbs and a pair of Obei SEMs. Patchpanel etc.

Quite a nice little box of fun. ;O)
