suggestions wanted for a totally f*cked & overloaded speaker bass sound?

I agree, but nonetheless her pedals (at least the early ones) are the worst-made anything I've ever seen that's been sold commercially. I've worked on - or rather, looked inside - two of the aptly-named Disaster Fuzzes, and I honestly couldn't tell you which, if either, was working 'right'. Given that the whole mess of components and wiring was wrapped in sticky electrical tape and almost impossible to get into without risking pulling wires off, I wasn't really interested in finding out...

From what I understand later ones are built better, but I haven't seen inside one.

ehx bass micro synth can give you all manner of mayhem, esp with the sub octave kicked in.
