RMX16

Effects by AMS

The AMS RMX16, introduced by Advanced Music Systems in 1982, was the world's first integrated microprocessor-controlled digital reverberation system. Its NonLin2 gated reverb programme defined the cavernous drum sound of 1980s pop and rock records, and the unit remains a benchmark for studio reverb to this day.
