Retro Pack plug-ins are a line of ‘classics’ that can live up to their own name without emulating something else. Retro Pack is packaged with three plug-ins - the 4020 Retro EQ, the 4030 Retro Compressor and the 4040 Retro Limiter. These plug-ins provide the fundamental tone shaping tools required for any production, with a unique tone that is all their own.
