I tested all of the distortion styles at the default setting. Some of these, especially the ones FabFilter calls “FX”, are going to go real crazy real quick when you push up the Drive knob. Foldback, for instance, looks pretty calm when the Drive is at 0%. It’s anything but calm above that.
I think this is the most fun channel strip plugin UAD offers. I’ve never worked on a hardware Vision so I can’t compare the sound or vibe, but I love tweaking on this plugin. And something about the layout attracts me like no other lover. (Or SSL channel strip.)
It’s been a while since there has been an update to this, but that might be because there is not much to improve on. You may have noticed most of the plugins I own are from the “big-name / expensive” guys, but PSP is that rare indie exception.
