Description
The USED Hart Audio Federal AM864v is a stunning hand-built recreation of the legendary WWII-era Federal AM864/U variable-mu tube compressor — originally designed for military broadcasting. This boutique unit captures the thick, syrupy compression and rich tube tone that made the original a secret weapon in mastering rooms and vocal chains. Painstakingly crafted by Hart Audio using high-end components, this version brings vintage mojo into the modern studio with reliability and style.
This unit delivers the kind of thick, warm compression you’d expect from rare vintage gear — without the maintenance or price tag of an original. A go-to for producers chasing that golden-era tone.
