Roland is best known for its legendary keyboards, but it also has a rich history in digital effects processors. Starting with early tape delays like the RE-201 in the 1970s, Roland’s innovation continued into the digital era with the SDE-2000 digital delay and the iconic SDD-320 Dimension D Chorus in 1981. Over the years, they introduced standout products such as the SRV-2000 reverb, famous for its characterful sound and use by Slash on “Sweet Child of Mine.” Roland’s attempt at high-end studio reverb with the R880 met limited success, leading them to focus on more affordable processors. The SRV-330 dimensional reverb and SDE-330 space delay are highly regarded, while the rare SDX-330 dimensional expander is famed for its superior chorus effects. Their final unit, the SRV-3030, was less successful and often confused with the well-regarded SRV-330, but they remain distinct products in Roland’s diverse effects legacy.
