so you want to Fuck Shit Up?

a sampler and maths would be a good start... I'd also add some sort of multi-fx and probably more in the way of modulation sources - and then some utility modules - a quad cascading vca, a matrix mixer...

plan your case around the modules you want & those you need to support them - rather than buying a case and then trying to squeeze modules in... I'd go for something like a mantis (nb that's a small case imo) - so you have room to (inevitably) expand into

Utility modules are the dull polish that makes the shiny modules actually shine!!!
