Manufacturer's Description from Heritage


  • Fully tube-based compression
  • Side chain filter for modern day needs
  • Immediate access to the continuously variable slope
  • Clean, intelligent design to guarantee many years of use


After decades of being so rare, hard to come by and almost considered mystical and near impossible to acquire, we are proud to introduce the HERCHILD Model 660 AND HERCHILD Model 670!


The Grandaddy of all compressors is BACK.

The original Fairchild has indeed been an essential part of the sound to so many hits during several decades. It certainly has earned its title as the ́grandaddy of all compressors. For years the industry has referred to this tube-based beast as something special, unique and even magic-like. 

Being based around 11 valves and 5 transformers you can be sure the HERCHILD Model 660 will imprint its signature sound all over your tracks providing that familiar tone that we've all come to love.

While staying true to the original in terms of response and sound, we ́ve been able to add a few things to make it more practical in modern day studios. First off we've given direct access to the continuously variable slope control. This is something that makes the compressor so much more flexible and was only available on the original via an inconvenient screw adjustment hidden from immediate access. Then there ́s the SC FILTER. Nowadays, it ́s just about impossible to fathom a compressor without this feature as it ́s become so important in everyday use. Here we've provided 4 different frequencies to choose from to precisely tailor your compression needs. We've also faithfully reproduced the exact attack and release times in the Time Constant section so you can confidently recreate the feel of its ancestor
