The Heritage Audio Herchild Model 660 captures the essence of the original classic compressor delivering the same unmistakable sonic signature that has graced so many records over the decades

Recreating a Classic…

Heritage Audio has spent years researching the original design and sourcing necessary components including the 11 NOS vari-mu valves required as well as custom made transformers, to recreate this classic without the issues of the older units. The result is a truly special compressor that imparts its unmistakable glue and character on any source it is used on.

… updated for the modern days'

Heritage Audio has also taken the opportunity to add features to make this legendary classic into a modern-day powerhouse. 

The Herchild 660 now offers direct access to the DC Threshold, a variable slope control that modifies the knee of the compressor. This feature was not easily accessible on the original and is know accessible at the turn of a knob.

In addition, Heritage audio have added a Sidechain filter with a choice of four different frequency points to choose from to specifically tailor the compression response to low-frequency. This feature makes this legendary compressor much more adapted for modern production techniques.
