Right away we can observe that there is noise, that is why the fr looks like this, other than that its flat. This indicates that DSC will be linear aswell.

Well, no phase issues either…

Well this is a tough one, I can see the analogue modeling and I can verify it, but the ratio at which it exists its a bit low, so I verify that it is there, but I also verify that its not as much as I’d expect.

The Character of the THD is aggressive and a bit smooth & rich. That is due to the 3rd order harmonic that is constantly almost stable, but also because 2nd order harmonics exist aswell but they are less stable and in a lower amplitude.

Interesting Fact 1:

The analog button in the GUI, just adds noise. When you’d expect to subtract the distortion as well .Here is the THD without the analogue button, the only thing that changed is that there is no noisefloor.

Is bound to be linear


Intresting fact 2 : The knee becomes hard only in the ratio of 10



So what can I say, I expected more distortion (specialy for this kind of unit)  but the modeling is there. The response is linear and the envelope is bound to be aswell, and the analogue button just adds noise…

So basically this is a ”partially” modeled plugin. It has the soul, but it lacks the heart (FR).


Q: Could you do a VS thread with other products that emulate this ?

A: Its gonna happen after the individual products are analyzed and reviewed.
