Roland Rhythm 77

The Roland Rhythm 77 (TR-77) drum machine was Roland's first product and was released in 1972. It is actually an updated version of the Rhythm Ace FR-8L produced by Ace Electronics and was one of a trio of drum machines released by Roland that year, but offering features superior to those of Rhythm 33 (TR-33) and Rhythm 55 (TR-55). It comes in a flat wooden case with a metal base, and, in keeping with its intended market among organists, it has a folding music stand on top of the unit.
