Eko’s Rhythm Box was an Italian preset analogue accompaniment machine, built around a panel of ready rhythms and a tempo control. Its compact cabinet brought an automatic beat into the everyday furniture of home and small-stage music making.

The rhythm lives below the panel.
Eko’s surviving K-334 schematic takes the story beneath the cabinet. It is a useful corrective to collector mythology: a rhythm machine is also a circuit, drawn line by line for somebody to understand and repair.

MauSS / Costume — Unus spiritus.
MauSS is credited with an Eko Rhythm Box on Costume’s Unus spiritus, alongside Yamaha and Technics machines. The release does not specify which Eko model, so the dossier keeps it at family level: a clear equipment credit without a false exact-model claim.

Y Create / The Blue Tape
The release story for Y Create’s The Blue Tape recalls early-1980s sessions with a Philicorda and a pre-programmed analogue EKO rhythm box, a deliberately corny counterweight to the duo’s darker electronics.

The 1971 Eko schematic records a distinct Rhythm Box design, while its front-panel logic remains simple and inviting: choose a rhythm, set the pace and play. The instrument was made to become a dependable partner for a musician who needed a pulse already in the room.
A documented market appearance
Beat Instrumental listed the Eko 4000X Rhythm Box among Eko rhythm units in August 1979 and identified ten rhythms. That record gives the machine a place in the retail channel of its day, separate from the company’s Music Box and Rhythmaker products.
A surviving Italian rhythm object
The Swiss Museum catalogue and firsthand collector inspection retain the Rhythm Box as a physical instrument with its own case and circuitry. Those records are a useful counterweight to the larger studio machines of the era: a smaller companion box can tell its own part of the story.
