"Grasso" (Italian for "Fat") is an effect for saturation, drive, compression, from subtle to distortion. A mixing and mastering effect.
- level-independent dynamics.
- level-independent dynamic filtering (on full signal, attack or decay).
- detailed control on tube circuits with several options.
- "spank" feature (post-drive dynamic response, on attack and decay).
- modeled "weak" power supply (more harmonics or "sagging").
- special post drive expander for great dynamics.
