Some instruments allow the keyboard to be split, the lowest octave or two producing a pedal-like bass tone. Although the sounds may bear such names as 'flute', 'string' or 'horn', they are not intended to sound like their orchestral namesakes - the nomenclature is borrowed from pipe organ tradition. A number of different pitches and tone-colours ('voices') were featured, often using rocker-switches, tabs or drawbars to function as 'stops' to select them. Most such instruments have no built-in amplification.Ī typical combo organ has one manual ( keyboard), covering four or five octaves, though a few models had two manuals of three or four octaves. Combo organs were best known for their bright, reedy sound their portability surprising versatility and relatively low cost. A combo organ is usually supported on a removable or folding stand or legs these originally would have been supplied as part of the instrument. A combo organ could best be defined as 'a portable electric organ designed to be used by a musical combo'.ĭetails A Continental organ by Vox, the same model heard on ' Light My Fire' by The Doors and ' In-A-Gadda-Da-Vida' by Iron Butterfly.Ī combo organ is an electronic portable organ, usually transistorized (although some older designs used tubes and later models, integrated circuits), that was designed for use on stage, usually in the context of a band or group. Combo organs ended up having a major impact on the music scene of the mid- and late 1960s, particularly on rock and roll of that era. They were the brainchild of necessity for portable organs of simple design, mainly for use in these small groups.

Combo organs were probably originally developed in the United Kingdom, based on the Univox polyphonic version of the Clavioline, and some models included the inner-workings of Italian-made transistor accordions. The combo organ concept, at least in the context of mass-production, is thought to have arisen from popular demand, when smaller home organs were seen in music stores. This type of organ predated, and contributed largely to, the development of modern synthesizers.
