The PRE-73 Jr MKII microphone and instrument preamplifier is a one-channel vintage-style with a signal path that uses only discrete components like resistors, capacitors and transistors. The input and output use two different transformers, each optimized for its purpose, so the audio components are built before integrated circuits become available.

The circuit used in the PRE-73 Jr MKII is like the preamp section in the classical 1073 module with a corresponding sound character that is warm, punchy, sweet and musical. These classic characteristics have been heard on countless recordings through the years and is a versatile sound that works very well on most sound sources and in most genres. The essence of this sound is now available at a surprisingly low cost, making it available to nearly everyone.
