I really like the fuzz in the Octaver; it's like screaming Octavia distortion. Another PitchFactor possibility is the HarPeggiator fuzz sequencer in the effects section.
Derelict78 might have been referring to the MangledVerb in Space, which I haven't checked out yet. I have gotten some raw dirtiness out of the Bias setting in TremoloPan, And you might try straight saturation in the TapeEcho algo for some overdrive.
