The AnaMod 660 500-Series Compressor is a faithful reproduction of the classic Fairchild 660, but with an AnaMod-style!

The Fairchild 660 limiter is one of the most famous and sought-after compressors ever made. The magical way it adds density and dimension to a track or a mix has been demonstrated on many of the best-sounding records made in the last 50 years. Using The AnaMod Process to model the complex transformer and tube interactions of the vintage hardware and re-implementing it entirely with analog components, the AnaMod 660 delivers a faithful recreation of the classic unit's sound and compression action. Unlike digital plug-ins or DSP-based outboard gear, there's no latency and no A/D or D/A conversions to compromise the sound.

Time Constants
Positions 1-6 are the original time constants. Positions 2a and 2b are variations on position 2 with longer release times suitable for vocal performances.

What We Think


The AnaMod 660 500-Series Compressor is very impressive in capturing the behavior and tone of the Fairchild 660, in a 500 series module. More impressive is the fact it does not use tubes at all. In my opinioin the Fairchild is the best compressor out there for drums. So that is where I like to put 660 variants. The AnaMod 660 does not disappoint at all. The punch, definition, and tightness you can get out of it, with a smooth musical character it provides is stellar for making your drums sound perfect. But, it can be dialed in on a more subtle side to enhance and glue a mix. Overall a great compressor.
