I try every bitcrusher plugin I can get my hands on, and there's something about the sound of Krush that really seduced me immediately. Very clear and detailed - and the variety of bitchrushy sounds it can produce is exhaustive. And this GUI is perfect. Clean, uncluttered and functional. You get immediate and detailed visual feedback as you make changes. I'm excited about this new developer. I haven't bought it yet, but Echorus sounds great too.
