YC-10Combo Organ / 1969
Yamaha introduced YC Series Combo Organs to satisfy the growing interest in portable organs created by the rise of the Beatles and other bands.
The YC-10 was the series' debut model. The YC-10 featured 49 keys on a single keyboard, and came in four different colors. The ability to store the organ in a compact suitcase is one of its standout features.
The reverse-colored keys can be converted into bass keys through the flip of a switch.
