Roland's Chorus effect that featured heavily on their JC Series guitar amplifiers was a unique and desirable sound back in the late 1970s and early 1980s.

The demand for this new chorus effect was so great, Roland developed the Roland SDD-320 Dimension D to satisfy that market demand, and it is quite possibly the greatest chorus effect processor ever made.
Roland’s chorus had a huge impact on recorded music particularly in the early 1980s. It almost defined the clean guitar sound from the early 1980s and onward. Guitarists like Alan Murphy used The Roland SDD-320 Dimension D rather than pedals in the studio, and you can hear this on his recordings with artists such as Go West and Kate Bush.
The Roland SDD-320 Dimension D is a specially designed chorus effect unit for adding spatial effects to stereo and monaural sound sources.
Monaural inputs are converted from a single point sound source into a sound which fills the entire stereo field. The Dimension D gives a new dimension without the apparent movement of sound produced by most other chorus devices.
The Dimension Mode selector button provide different effects, MODE 1 produces the softest effect and MODE 4 produces the strongest effect. At OFF the sound passes through the SDD-320 without change.
Listen to Alan Murphy on guitar in this classic Go West song ‘Don’t look down’.
