Hammond X66 (1967–1975)
A rare, high-end electronic organ with tone-wheel generation, four drawbar sets, and 18 changeable presets. It was Hammond's most expensive model.
Overview
Hammond built the X66 electronic organ from May 1967 until sometime between late 1973 and early 1975. It has a top-octave tone-wheel generator with 12 tone wheels. An internal amplifier drives seven speakers and two high-frequency horns. It's a console instrument with two 61-note keyboards and a 25-note pedalboard. Hammond positioned it as the flagship, and it was noted for its futuristic appearance and advanced feature set for the time. The dedicated output connects to the X-77 Leslie speaker system only. Four more output sockets link to an external audio mixer and power amplifier, so the sound can be routed elsewhere.
