Korg KR-55, sweet sounding preset drum machine from the early 80's. This machine looks to have never been used. Time capsule clean with the original box, user manual, plastic cover, footswitch and a printed catalog of Korg's product line. You won't find another in this condition.
More info from our friends at VSE:
The KR55 was, for its time (1979), an advanced preset rhythm drum machine with up to 96 preset rhythm patterns! These patterns cover the whole gamut of presets (Waltz, Samba, Rhumba, Bossa Nova, Tango, Slow Rock, Swing, Rock, etc.). The KR55 also featured a "swing beat" control to add a variation to the groove. Each drum sound's level can be individually adjusted for each pattern. It can also be externally controlled via footswitch jack for the Start/Stop and Intro/Fill switches.
