The Hammond organ is an electric organ, invented by Laurens Hammond and John M. Hanert [1] and first manufactured in 1935. [2] Various models were produced, which originally used tonewheels to generate sound via additive synthesis , where component waveform ratios are mixed by sliding switches called drawbars and imitate the pipe organ's registers.
The Hammond Organ Company produced an estimated two million instruments in its lifetime; these have been described as "probably the most successful electronic organs ever made". [40] A key ingredient to the Hammond organ's success was the use of dealerships and a sense of community.
The pipe organ is a musical instrument that produces sound by driving pressurised air (called wind) through the organ pipes selected from a keyboard.Because each pipe produces a single pitch, the pipes are provided in sets called ranks, each of which has a common timbre, volume, and construction throughout the keyboard compass.
the row of organ pipes used to create a particular sound, more appropriately known as a rank; the sound itself; Organ stops are sorted into four major types: principal, string, reed, and flute. This is a sortable list of names that may be found associated with electronic and pipe organ stops. Countless stops have been designed over the ...

Organ pipes are physically organized within the organ into sets according to note and timbre. A set of pipes producing the same timbre for each note is called a rank, while each key on a pipe organ controls a note which may be sounded by different ranks of pipes, alone or in combination. The use of stops enables the organist to selectively turn ...
By then, groups were preferring to use a Hammond organ and Leslie speaker instead of a Vox. Most of the remaining assets were sold at a liquidation sale in 1971. [22] There are no definitive figures for how many Vox Continentals were manufactured. However, estimates based on serial numbers indicate 9,100 single-manual organs were manufactured.
Hammond organs differ from pipe organs in that pipe organs can only pull a stop out (that is, turn on a stop) or push it in (turning off this stop); in contrast, Hammond organs typically have drawbars, so that the player can control how much of each "pipe rank" (e.g., 16 ft, 8 ft, 4 ft 2 ft, etc.) they wish to use. Synthesizers can program ...
