The instrument
The EM-130 probably appeared on the market in 1973 as part of an EM series. It is a combination of a mixer with 6 channels, a spring reverb and a drum machine. It is very similar in design to the Italian LEM Baby Tape Echo Mixer, which was released around the same time.
Details
The six channels of the EM-130 are adjustable for balance, reverb echo, treble, bass and volume. There are also controls for Aux Volume, Tuner, Master Reverb Echo and Master Volume. The drum machine's presets are 2 Beats, Waltz, Swing, Slow Rock, Jazz Rock, Rhumba, Bossa Nova and Tango.
