Decapitator is an Analog Saturation Modeler. It has long been the magic mojo that engineers have used as their swiss army knife of mixing. It's used on drums, bass, vocals guitars, everything. It can be used to beef things up, thin things out, give them some edge, fry them up nice, add a bit of warmth, pull things out of the mix, or even create a signature sound. Used subtle to extreme, analog saturation is the golden child of great mixes.
