Two quick demos without much ado:
Flight of Harmony Plague Bearer
(processed signal first, then source material)
A little too idiosyncratic for my taste, but a good, cheap FSU module.
MFB DRM04 Kick Drum Module
This module is fully CV-able and is capable of a wide variety of sounds - the trigger sensitivity has a marked effect. The overdrive is great, if a little 90's. You can download the zipped folder (12MB) here.
