The new Cherry Audio Mercury-4 is a detailed emulation of one of the best-sounding and quirkiest polyphonic synthesizers of the late 1970's, the Roland Jupiter-4. It's the rarest and most sonically unique of the fabled Jupiter series, and we've gone to great lengths to recreate the subtle (and not-so-subtle) nuances and character of this beloved classic. Every aspect of Mercury-4 has been expertly modeled upon a vintage Jupiter-4 originally owned by Greg Hawkes of the legendary 80's new wave band The Cars, and played on their double-platinum 1981 album Shake It Up. In Greg's own words, Mercury-4 "sounds just like my old Jupiter. It's nice to have it back."
