GEM Rodeo 49 analog electronic organ.

The GEM Rodeo 49 electronic organ is typical of the type of electronic keyboard commonly seen before the rise of affordable, user friendly synthesizers, and so has a place in the narrative of the Sound Technologies collection, in terms of the development of such technologies through the 20th century.

This model incorporates a simple analog drum machine with 5 rhythm presets, and “Magic Chords”, which is a kind of auto-accompaniment synched to the drum machine.
