This compact pedal provides a digital delay effect with outstanding quality equivalent to that of a dedicated rackmount delay unit, all with simple stompbox-style control.
As Roland developed more digital effects in the early 1980s, one of their best-sellers was the SDE-3000 digital rack delay. A high-ticket item, it was only really within reach of studios or pro users like Steve Vai and Eddie Van Halen; however, engineers worked out that the bespoke delay IC could just fit into the same form factor enclosure as their DM-2 analog delay, and after extensive testing, the DD-2 delay was born.
The legend goes that in 1986 the price of this component dropped substantially, allowing Roland to reduce the price of the pedal. To avoid a perceived reduction in quality, they rebranded the DD-2 as the DD-3, a fate shared by the DSD-2, which became the DSD-3.
