Can anyone help with Wobbles....

Hostile Nature

I Duz Minimalz...
Ez all

This isn't your standard wobble question, I'm well aware of how to get wobbling, what I'm trying to re-create is the type of wobble in Hazard - Killers Dont Die & Billy The Kid - The OZ - the type that wobble that sort of "morphs" in..

I'm guessing I need some sort of envelope on the low pass cut off maybe

I've been able to create the effect slightly but not really to the same clarity or punch of these wobbles

any tips or suggestions?
