Sounds interesting... I'll have a look if I can find a store here in Holland
which sells that kind of stuff.
I could use this rare though dead LFO epoxied block as a paper weight or...
I could try to dissolve the epoxy, reverse engineer the module and build a
working new one. Option two sounds like a lot of more fun to me. :-)
