Kjaerhus Audio is taking the concept of bread and butter plug-in effects to the next level in terms of sound quality. This is probably the best, most lush sounding chorus effect on the VST scene, even when one compares it against commercial offerings. The GUI is functional, though looks a tad bit like an old 80s bit of 1/2 space rack equipment, and looks almomst exactly like all the other Kjaerhus Audio GUI's making it hard to distinguish it from the others so it lost two points from me there. Also it seems to lack a proper manual, though anyone who has used a chorus effect in the past will have no trouble figuring out how to use this. But these are my only qualms, and it's the sound the counts most and this where this chorus really excells. In all honesty I've never been a big fan of chorus effects in general, but this plug-in has me running vocals, guitars, basses, and keys through them like there's no tomorrow (ok I'm exagerating a bit, but suddenly I really do like choruses). Anyone using VST effects should have this chorus on their hard drive.
