found: New Grove, 2nd ed. WWW site, Nov. 15, 2002(Electric organ: A term used of certain types of electronic organ that are not fully electronic. It is sometimes applied indiscriminately to all electronic and electric organs, or more accurately to those instruments that include either electroacoustic or electromechanical elements, in order to distinguish them from instruments in which the sound-generating system consists of electronic oscillators with no moving parts. Most precisely it describes only those electroacoustic organs in which, like the electric guitar and electric piano, the acoustic sounds of the vibrating mechanism are reduced and made audible by means of special pickups or transducers; the sound sources have usually been free reeds, as in the reed organ. Until about 1930 the term "electric organ" usually meant a pipe organ in which electricity powered part of the action; such instruments are now referred to as "organs with electric (or "electro-pneumatic") action.")
