The original LA-3A Audio Leveler made its debut in 1969 and was an instant hit. Studio engineers loved the half-rackspace solid-state electro-optical compressor for the punchy dynamic control it delivered on electric bass, guitars, and just about any other source. Sweetwater knows you want one, and we have good news: the Golden Age Comp-3A re-creates the circuitry, sonics, behavior, and form factor of the classic - and it's delightfully affordable. The vintage-style circuit uses no ICs. The I/O is transformer balanced. And the sound? Warm and deliciously musical. Treat yourself to classic compression, with the Golden Age Comp-3A. Golden Age Comp-3A Compressor Features: Vintage-style circuitry with no integrated circuits Transformer-balanced I/O Capable of driving most balanced or unbalanced loads Internal jumper for selectable output-transformer loading Lets you vary high-frequency response Employs classic T4-style electro-optical attenuator for gain control Program-dependent attack and release times Easy 2-control operation: Gain, Peak Reduction HF
