Oh, hell yes! If this is going in that Dreadbox cab, really all that's left some way to get back down to line-level out of the Dreadbox's Mixer A, and there should be a 2hp solution for that. Or just use the System-1's outs. This is quite open-ended.

Normal synth, row 2, abnormal synth, row 1, and all the right bits. Nice...
