What it is

Tubechild 670 is a vari-mu tube compressor plugin modeled after the Fairchild 670, a revered 1950s studio legend. Antelope Audio deconstructed a well-preserved original unit and measured every component - all 20 matched valves and 14 vintage transformers - to recreate its character. The result adds natural warmth and thickness with no artifacts, distortion, or noise.

Who it's for

Mix engineers and producers who want vintage analog glue on buses, stems, or the master bus. Especially useful for genres where warmth and cohesion matter - hip-hop, jazz, soul, and dense mixes that need taming without sounding over-compressed.

Key features

• Circuit-modeled compression based on physical measurements of a real Fairchild 670 hardware unit
• Six timing curves for variable release time let you shape the compression envelope precisely
• Adds natural tube warmth and thickness to individual sources and bus processing
• Grips transients firmly while maintaining the organic, lush character the original hardware is known for
