Roland Juno-106

The Juno-106 is the most-sampled synthesizer in history, thanks to its lush chorus effect, simple one-oscillator-per-voice architecture, and instant patch recall. It became the default pad and bass machine of the 1980s, powering hits by Depeche Mode, OMD, and countless synthwave artists. When producers say "analog warmth," they are typically describing the Juno chorus—a sound so distinct it is more instantly recognizable than #1 Moog Minimoog's filter in pop contexts. Used prices have surged from $300 in 2010 to over $3,000, a 900% increase that makes it the best-performing synthesizer investment of the last decade, faster than the average vintage synth appreciation of 150%.
