Roland SDE Series Series

The Roland SDE Series, introduced in the early 1980s, established Roland as a leader in digital delay technology. Beginning with the SDE-2000 and followed by models such as the SDE-2500, SDE-3000, and later the SDE-330, the series delivered clean, stable delays with precise time control and modulation capabilities. These units offered programmable memories, external control options, and high headroom, making them ideal for both studio and live use. The SDE-3000 in particular became a studio classic, prized for its warm yet detailed sound and used by countless guitarists and producers throughout the 1980s and 1990s. Reliable, musical, and technically advanced for their time, the Roland SDE Series remains one of the most respected lines of digital delays ever produced.

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.
