toodee is spot on here. This is one of those examples where modular is NOT the solution.
While it seems like modular is the Royal Road to raw sonic power, it's often the case that one can cobble up something in modular that doesn't work as well as an off the shelf patchable and which also winds up costing considerably more than that not-as-sexy solution. Small systems are especially prone to this problem, notably ones in which users try and populate very small cabs. But the REAL use for those, tbh, is to allow for expanding existing systems with a few specific modules. Think a Maths might beef up your MS-20 mini? That's what those minicases are for. But when you house a voice module in one, add the cost of the cab, one or two possibly (or not) useful additional modules, you often find that all that's happened is that you've replicated the functionality of an existing off-the-shelf solution for sometimes twice the money. Not good.
Here's a suggestion...when doing a build on MG, I'll start off TOO big, then start reducing the setup until I've arrived at a minimum for what result I'm looking for. But at the same time, if you can keep reducing things to the point where you're arriving at a result that's comparable to (but more expensive than) an off the shelf device, go with the off-the-shelf device. You'll often find that the same amount of money spent on the modular will get you MORE power from those, since the cost of one modular solution can often come in at twice (or worse) the amount of similar patchables, etc.
