About Golden Age Project COMP-3A Jr

When it comes to achieving a classic, vintage sound, the COMP-3A Jr 1-Channel Vintage Style Tube Compressor/Leveler stands out with its unique design and high-quality components. This one-channel compressor/leveler utilizes a discrete analog signal path, composed solely of resistors, capacitors, diodes, and transistors, a design reminiscent of the golden age of audio equipment before the advent of integrated circuits.

The COMP-3A Jr's input and output are transformer balanced, employing two distinct transformers, each meticulously optimized for its specific role. This design choice harks back to a time when audio components were crafted with precision and care, resulting in a sound quality and character that many modern users find superior to that produced by contemporary technology.

The COMP-3A Jr's circuitry is based on classic design principles and incorporates an integrated optocoupler to control gain. This unique feature imparts the COMP-3A Jr with distinctive compression characteristics, adding a rich, musical texture to the sound.

The vintage-style signal path of the COMP-3A Jr not only enhances the overall sound quality but also adds a warm, musical character that is often sought after in the world of digital audio recording.

This combination of classic sound, vintage design, and user-friendly interface has made the COMP-3A Jr, and similar vintage-style products, favorites among audio engineers and musicians worldwide.
