FETish is Analog Obsession's free FET compressor in the 1176 tradition: fast, aggressive gain reduction that loves drums and parallel buses. It is not a UA-licensed recreation. It is a freeware tool that many mixers keep because it delivers the right kind of grab without a license fee.
It excels when you need free punch. Snare, kick, room mics, and full drum bus parallel paths are natural homes. All-ratio-style aggression is part of the appeal for rock and electronic hybrid drums. As part of Analog Obsession's wider free suite, it sits next to optical and bus tools so a starter analog-style rack costs nothing but disk space.
The trade-offs are polish and provenance. Official UAD or Waves CLA-76 collections offer different modeling priorities and support structures. Always download from Analog Obsession's official site or linked Patreon posts—third-party mirrors are a security risk for free plugins.
Choose FETish for free FET color. Choose CLA-76 or a UAD 1176 collection when you want commercial brand tools, or Molotok when you prefer free TDR character compression instead. Support the developer if the plugins become part of your daily chain.
