576 Blue Stripe
Rev A FET Compressor
Classic FET Compression, Reimagined
576 Blue Stripe draws direct inspiration from the revered 1176 Revision A, known for its speed, attitude, and unmistakable sonic signature. The design retains the core FET compression topology that defined countless recordings of the 1970s.
Transformer Input and Class A Output
At its front end, the compressor uses the same style of high-quality input transformer responsible for the original’s warmth and harmonic density. A pure Class A output stage ensures clarity, punch, and headroom throughout the signal path.
Ultra-Fast Transient Control
With an attack time of just 20 microseconds, the 576 Blue Stripe captures and shapes transients with surgical precision. This makes it ideal for taming aggressive peaks while preserving energy and immediacy.
Six Compression Modes for Total Control
Six ratio settings provide exceptional flexibility, from gentle 2:1 compression to hard limiting at 20:1. The SLAM mode recreates the iconic “all-buttons-in” behavior, delivering explosive dynamics, saturation, and unmistakable character.
Built for Character and Versatility
Equally effective on vocals, drums, and bus processing, the 576 Blue Stripe balances vintage tone with modern functionality, offering relay-controlled bypass and expanded control options for contemporary production environments.
