AnaMod Audio AM660

If you're looking for that legendary, thick Fairchild 660 tone without having to take out a second mortgage or maintain high-voltage vacuum tubes, this module is one of the best choices available. AnaMod uses pure, complex analog modeling (no digital DSP, no latency) to faithfully recreate the exact sonic footprint, compression curve, transformer character, and speed of the iconic Fairchild 660 variable-mu limiter.

It works wonders on vocals, acoustic guitars, bass, acoustic drums, and the mix bus, adding instant weight, warm glue, and smoothness.

Key Features

- 100% Analog Signal Path: Uses physical analog modeling circuit technology (no digital conversion or latency).

- Classic Fairchild Character: Recreates the non-linear response, variable-mu distortion curve, and time constants of the original unit.

- Time Constant Switch: Features all 6 original Fairchild 660 attack/release presets plus 2 additional modern variations.

- Standard 500-Series Format: Fits into any standard VPR Alliance / 500-series rack chassis.
