It's really good. I've been waiting for a Sansamp PSA clone in VST for a long time. THE GOOD: It sounds lot like a real sans amp and is usable on windows and mac in all formats. The stereo mid side stuff is neat and works well. The phase flip, and analog component variance is also very cool.
THE COULD BE BETTER:
I find the dry wet knob to not be very useful because of the gain staging in the plugin. Both the Output and Level of the plugin effect the level of the dry signal for some reason.... so usually the dry signal ends up being way too quiet and. It would be good if we had a way of balancing the level of wet vs dry so the mix knob was more useful.
The CPU usage is pretty high. It seems this plugin is always oversampling by 2x or 4x? It would be cool to have an option to control oversampling. Sometimes I'm not concerned about Aliasing at all and would prefer the lower CPU hit, and sometimes I want it to be best possible quality.
