Having shaped and influenced 1,000s and 1,000s of hit records over the last 6 decades it´s easy to say that the original could be declared one of the most important pieces of recording equipment of all times. Unfortunately, only around 500 or so units were produced and after so many years of use and abuse not many are available nowadays or in useable condition. That makes this an extremely rare and expensive item that is hunted down all around the world. You´d have to consider yourself lucky to find one. Now, all that changes as we are proud to introduce the HERCHILD Model 670. A faithful reproduction to the original as it is stuffed full of 22 valves and 9 transformers, operates at a very high voltage and uses only the best components to deliver the utmost quality possible. This is immediately recognised during use as there are no audible thumps produced in addition to extremely low distortion and noise making it perfect for Mixing and Mastering duties. We´ve been able to successfully follow the original design and trace the necessary components to provide a modern day alternative while keeping it fully tube-based. It´s taken us years, but we feel we´ve 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. 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 DC THRESHOLD (Slope/Ratio/Knee) 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.
