Roland SDE-2000 Digital Delay

Roland’s first digital delay, the Roland SDE-2000 was a big hit when it arrived, guitarists took to it like a duck to water, as too did home recording studios. It may have had limited bandwidth with the relatively low sampling rate of 26kHz, but that did not stop the success Roland enjoyed with the SDE-2000, but it did kill off the Space Echo, for a while at least.

AMS DMX15R Digital Reverb

The AMS DMX15R was designed as a digital reverb add-on for the AMS DMX 15-80S digital delay system. However, it is uncertain if this product was ever mass-produced, and if it was, it remains extremely rare. It is more likely that the AMS DMX15R was eventually developed into a standalone digital reverb unit (AMS RMX 16) that did not depend on the AMS DMX 15-80S to operate.
