Classic 1073 Preamp/EQ for a Song The legendary 1073 wrote the book on characterful mic preamplification and equalization. These venerable circuits helped define the big, punchy sound of ’70s rock — and countless recordings and live concerts ever since. Today, this coveted tone can be yours for a song, with the Golden Age Project PREQ73 Premier. A vintage-style, single-channel mic/line/instrument preamplifier and 3-band EQ with inductor-based midrange, the PREQ73 Premier employs all-discrete circuitry similar to the that of the preamp and the equalizer sections of the venerable 1073 console module. This results in a sound that is warm, punchy, sweet, and musical. The preamp provides 80dB of gain that lets you mic subdued sources with your favorite passive ribbon mics.
