Heritage Audio Herchild HA660 Ardent Edition Mono Tube Compressor

When you hear records made at Ardent, you are listening to the heart and soul of Memphis and from here on out, that spirit is captured by the Heritage Audio HERCHILD Model 660 Ardent Edition.

Ardent Recording Studios is one of the most iconic music studios in the world. Known for its creative energy and technological excellence, it’s been home to a wide range of unique and talented recording artists, producers, and engineers, and has witnessed the creation of many timeless recordings that have influenced the direction of modern music and music production.

So it is easy to understand that when Ardent Studios first contacted Heritage Audio to evaluate the possibility of having an Ardent Edition of their HERCHILD to substitute their original Fairchild units they could barely believe it. Since its release, the HERCHILD has stablished itself as the industry reference for “Vari-Mu FAIRCHILD” compression all over the world, but with this request from Ardent they now had a new challenge…a unique opportunity to take it to another level.

But, what is so special about the original Ardent’s Fairchilds? Ardent’s team modified the attack and release times of their original units in the early 70’s so that the time constants were faster and, therefore, more usable for modern recording studios at the time. These mods were first used to track Jimmy Page’s acoustic guitars on Led Zeppelin III and it is been a best kept secret…until today. After receiving the pencil on paper notes from the original modifications, the Heritage Audio team has worked together with Ardent’s to nail the time constants of the original and after several months the HERCHILD "Ardent Edition" is a reality. Ardent’s team were so impressed by the performance of the HERCHILDs that they have changed their original units for 4 HERCHILD 660 and a HERCHILD 670.

For almost 60 years Ardent has been a special creative space for a diverse and world-renowned clientele; recording artists such as Led Zeppelin, Sam and Dave, ZZ Top, R.E.M., Isaac Hayes, The Staple Singers, Stevie Ray Vaughan, BB King, The Bar-Kays, The White Stripes, Big Star, Bob Dylan, The Raconteurs, The Gin Blossoms, Stevie Wonder, Steve Earle, Smashing Pumpkins, The Allman Brothers… just to name a few. Now you can own a legendary piece of gear that has been the centerpiece of so many multi platinum recordings for decades.

COMMON TO ALL HERCHILD 660 ITERATIONS:

For years the industry has referred to this tube-based beast as something special, unique and even magic-like. 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. 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. Although it was originally designed to be used for cutting lacquer masters for vinyl albums it didn’t take long for engineers to realize that it could do much more. It soon became an essential studio tool for many innovative artists, engineers and producers and could be found in most professional studios.

As there were only about 500 units originally produced there just simply aren’t enough to go around for everybody. Add to that the original requires quite a lot of special maintenance and after nearly 60 years there just simply aren’t many still in good shape. So that’s where Heritage Audio comes in…

Heritage Audio has been able to successfully follow the original design and trace the necessary components to provide a modern day alternative. It’s taken Heritage Audio years, but they feel that they have finally produced something so special that it’s capable of letting the old grandaddy take a long deserved rest, and make room for the new blood to take over.

It’s been quite a long journey, from sourcing thousands of NOS Vari-Mu tubes from all around the world to commissioning the best names in the industry for making the needed custom transformers.

While staying true to the original in terms of response and sound, Heritage Audio has been able to add a few things to make it more practical in modern day studios. First off they have 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 Heritage Audio has provided 4 different frequencies to choose from to precisely tailor your compression needs.
