Heritage Audio Herchild Model 670 Details

The Heritage Audio Herchild Model 670, with a complement of 22 valves and 9 transformers, functioning at elevated voltage levels, it attains a resolute and accomplished outcome. The Heritage Audio Herchild Model 670 can yield a pristine, uncoloured sound devoid of artifacts or pulsations, all while possessing the capacity to cultivate a more pronounced, weightier, and richer impact, enriched by additional harmonics when subjected to heightened pressure.

Originally conceived for the purpose of broadcasting and the precision cutting of lacquer masters intended for vinyl albums, the Fairchild compressor underwent a transformative journey, ultimately solidifying its status as one of the most renowned and coveted compressors in history. Emerging during the latter part of the 1950s, its production numbers remained relatively modest. Today, several decades later, only a fraction of these units endure, and an even smaller subset have been meticulously maintained to meet the rigorous demands of modern production.

The distinctive and captivatingly rich sonic character of the Fairchild compressor, characterised by its lusciousness, impactful punch, and enveloping warmth, has graced countless chart-topping creations. Remarkably, its appeal has stood the test of time; rather than fading into obscurity, its allure has only intensified. This enduring admiration persists, if not flourishes, in the contemporary era dominated by digital technology.

In an age where the hunger for analogue artistry in the realm of sound manipulation continues to surge, Heritage Audio steps forward with a compelling solution: the Heritage Audio Herchild Model 670. This ingeniously crafted device encapsulates the cherished essence of the original Fairchild while accommodating the needs of present-day audio craftsmanship.

Great unit. Durable (40 years old and still going unlike the imported stuff being offered today). I own several different delays (I.e. ADA, Lexicon, and multi effect units) and this thing matches up to the best of them. Recommended!
