Golden Age Audio Project Pre73 JR Mk2 Direct

The little brother of the classic PRE-73The PRE-73 Jr MKII is a vintage-style one-channel microphone and instrument preamplifier, designed to deliver the waallrmth and character of classic analog gear. Featuring an all-discrete signal path with transformer-balanced input and output, it preserves the integrity of your sound using carefully optimized components—just like the revered designs of the pre-integrated circuit era.

While modern integrated circuits prioritize efficiency, many musicians and producers seek the unmistakable tonal depth of vintage equipment, especially in today’s clean, digital recording environments. This demand has fueled the revival of iconic circuits, often making originals highly sought after on the second-hand market.

The PRE-73 Jr MKII is modeled after the legendary 1073 module, offering a warm, punchy, and musical sonic character heard on countless recordings. Its versatile, rich tone complements a wide range of sound sources and genres, bringing the essence of classic studio equipment to a surprisingly accessible price point.
