Univox SR-55 - Rhythm machine made by Keio Electronics, Japan, 1972 as the "Korg Mini-Pops 3." The Keio people had these marketed by Univox in the U.S.A. This has 20 rhythms, a tone knob, and two extra variation knobs for the fox-trot rhythm. Some nice vintage sounds, particularly the latin rhythms. Kraftwerk used one of these in the early days.
