Details
Controls: Time Constant (6 custom Ardent-derived attack/release settings), DC Threshold, SC Filter (4-position)
Notable use: Ardent Studios replaced its original Fairchilds with 4x Herchild 660 + 1x Herchild 670 (this edition uses Ardent's custom 1970s time constants, first used on Jimmy Page's acoustic guitars, Led Zeppelin III)
Notes: Sourced page listed channel count as 'stereo' but this contradicts the mono Fairchild-660-style base unit and Ardent's own use of 4 separate mono 660 units — likely a page/extraction inconsistency; channel_count kept at 1 (mono) to match the base Herchild 660 platform, flagged for verification. Price is MAP; limited edition.
