Electro-Harmonix Low Frequency Compressor 1978 in excellent cosmetic condition fully orignal (just 9v battery clip was changed) and perfect working order.

This rare vintage unit from the mid seventies remains in exceptional cosmetic and functional state. It is a specialized optical compressor designed to smooth out low end transients while maintaining the natural punch of your instrument. The circuit is famous for its warm analog squash and subtle saturation that defines the early ehx era. It features a simple interface that provides transparent leveling and enhanced sustain for bassists or guitarists seeking a thick foundation.
