I've got 8hp left in my rack for reverb. I could pull a couple 2hp modules that get little use to make 12hp happen if need be. I play around with the psy ambient, droney, lo-fi, spacey stuff and want huge reverb. Can I get that in a 12hp module? I've been looking at TipTop Zverb but I'm open to whatever. Does it make more sense to buy the module or run everything through an external effects unit like Strymon Nightsky or Big Sky?
