Another Rhythm King! This is 4th version of Maestro’s Rhythm Kings. The MRK-4 Drum Machine is beautiful in side and out built similar to organs of the time and used tuned tanks just like the TR-77 with some unique modulation features.
The 2nd version of the Maestro Rhythm King drum machine didn’t change the essential sound much, but instead offered an array of pre-programmed settings. It was popularized by groups such as Sly and the Family Stone.
This early analog drum machine was used by the sonic visionary, Sly Stone. He called it “The Funk Box.” It only has 18 preset rhythms, pitch control, and triggers to play specific sounds.
