Simply put... it is an unmatchable distortion unit. I am one that believes in the subtleness of sounds... the slight variations that add a little ear/brain candy to the mix and this lets me dial in just the right amounts. While for me its still an experiment until i find success plugin... i truly appreciate it.
It seems to have a problem with saving its control state upon loading, so that is annoy cause I have to reprogram it often.
However, I think it is usually worth it. :)
I do not know what this thing does to the sound, but it seems to add distortion in a multiband fashion... however, it never get THICK or CrUnChY... at high doses it tends to become weak.
I don't really think my ears are good enough to know exactly what Aliasing is, but if I had to guess, this probably does a lot of it, because the sounds become "sharp" and almost "square" like at high settings. I never drive things that hard, but unless it is SUPER extreme, it still seems to maintain a musical quality i enjoy.
