Robert Schwarz
EXACTLY what I was looking for

I love the graphic interface and the delta mode, that's makes audible whats being cut. I've never felt like I had this much control over my signals. It goes from peaky clean clipping to lovely saturated limiting. I primarily use it for rock and metal productions. There isn't an instrument that doesn't respond well to this plug in. Drums, guitar, bass, busses and solo alike. It's literally on every project since I got it
