FabFilter Saturn 2

FabFilter Saturn 2 is a high-quality distortion/saturation plug-in with a huge range of distortion models ranging from subtle to screaming vintage amp modelling, multiple frequency bands, hugely flexible modulation system, and a very modern, well-designed user interface.
The Saturn 2 app filters the microphone input and plays it back in real-time. To use Saturn 2 as a plug-in, you need an AUv3-compatible host app like Auria, AUM or Cubasis. Saturn 2 will appear in the list of Audio Unit extensions for effect plug-ins in the host app.

"I've found a plugin I can’t live without. There’s not one single type of instrument that can't benefit in some way by having some Saturn on it. [...] Whether you’re looking for a subtle push in the mix or all out audio destruction, Saturn has you covered. Verdict: 9/10!"

"The quality of the algorithms is palpable: the amps, tubes and tape types feel suitably 'real' but more sonically interesting than most, and the movement and 'funk' that can be imposed on them is nothing short of dazzling."
