Roland Juno-106

The Juno-106 is the most-sampled synthesizer in history. Its lush chorus effect, simple one-oscillator-per-voice architecture, and instant patch recall made it the default pad and bass machine of the 1980s. Depeche Mode, OMD, and a thousand synthwave artists owe their sound to it. When producers say "analog warmth," they're usually describing the Juno chorus. Used prices have gone from $300 in 2010 to over $3,000, making it the synth equivalent of a vintage Porsche.
