Lilac Cloud is a fuzzy overdrive that started off as a Harmonic Percolator but was tweaked, expanded and de-mojoed.
I have no idea if it sounds like one. I have never tried a real one and they all seem to be different anyway.
I just liked the grain and wide range of distortion that this configuration provided, allowing to go from an almost clean boost to a thick compressed fuzz.
It also has an EQ section, optional clipping, self-oscillation and it has Flab!
