AMS is a British audio equipment manufacturer that has been producing high-quality professional audio products for over 30 years. The company was founded in 1981 by Mark Crabtree, a talented electronic engineer with a passion for developing innovative audio equipment. In the early days, AMS (Advanced Music Systems) focused on developing high-quality digital signal processors, including the AMS RMX16, which was one of the first digital reverb units to be widely adopted by musicians and producers. The AMS RMX 16 became highly popular due to its natural-sounding reverb algorithms and its intuitive user interface, which allowed users to quickly and easily create a wide range of reverb effects.
