Vintage Korg Rhythm-55 model KR-55 for sale. This unit has been professionally serviced and fully tested and is working perfectly.
Although this model is non-programmable, it sounds great and has quite a few useful preset patterns onboard. Used by Depeche Mode on their first album Speak & Spell. That album was made around 35 years ago and still sounds like the future, thanks in part to a KR55 just like this one. :)
