Clonewheel organ

"Clonewheel organ" is a jargon term used to refer to an electronic musical instrument that emulates (or "clones") the sound of the electromechanical tonewheel-based organs formerly manufactured by Hammond. The phrase "clonewheel" is a pun on the term used to describe how the original Hammond produces sound: through "tonewheels". The first generation of clonewheel organs used synthesizer voices, which were not able to accurately reproduce the Hammond sound. In the 1990s and 2000s, clonewheel organs began using sampling or digital signal processing techniques, which were much better able to capture the nuances of the vintage Hammond sound.
