A clonewheel organ is an electronic musical instrument that emulates (or "") the sound of the electromechanical Hammond organ formerly manufactured by Hammond organ from the 1930s to the 1970s. Clonewheel organs generate sounds using solid-state circuitry or , rather than with heavy mechanical tonewheels, making clonewheel organs much lighter-weight and smaller than vintage Hammonds, and easier to transport to live performances and recording sessions.
The phrase "clonewheel" is a play on words in reference to how the original Hammond produces sound through "". 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 digitally-sampled real Hammond sounds or digital signal processing emulation techniques, which were much better able to capture the nuances of the vintage Hammond sound.
Clonewheel organs can be either electronic keyboard-based instruments such as the Korg CX-3 or the Roland VK-7; or keyboardless emulation devices, which include MIDI-compatible , such as the E-MU B-3 module and software-based "virtual synths" (such as the B4 by Native Instruments discontinued). To use keyboardless emulation devices, they need to be connected to a MIDI keyboard.
The Hammond organ is an electronic organ that was designed and built by Laurens Hammond in 1934. While the Hammond organ was originally sold to churches as a lower-cost alternative to the pipe organ, it came to be used for jazz, blues, and then to a greater extent in rock music (in the 1960s and 1970s) and gospel music.
The original Hammond organ imitated the function of a pipe organ's ranks of pipes in multiple registers by using additive synthesis of from harmonic series to generate its sounds. The Hammond organ's individual waveforms were made by mechanical which rotated beneath electromagnetic pickups. The component waveforms can be mixed in varying ratios by using drawbars mounted above the two keyboards. Hammond organs also have a harmonic percussion effect, in which the 2nd and 3rd harmonic tones can be added to the attack envelope of a note.
Hammond organs have a distinctive percussive key click, which is the attack transient that occurs when all nine key contacts close, causing an audible pop or click. Originally, key click was considered to be a design defect and Hammond worked to eliminate or at least reduce it by using equalization filters. However, some performers liked the percussive effect, and it has become part of the classic sound that modern imitators of the Hammond organ have tried to reproduce. The classic way of enhancing the sound of a Hammond organ is to use a rotating speaker known as a Leslie speaker or cabinet.
Some early emulation devices from the 1970s were criticized for their unrealistic imitation of the Hammond sound, particularly in the way the upper harmonics were voiced, and in the simulation of the rotary Leslie speaker effect. Refinements to Hammond emulations eventually led to the development of relatively light electronic keyboard instruments such as the Korg CX-3 (1980), and the Roland VK-1 (1980), which produced fairly realistic re-creations of the Hammond tone. While these instruments were widely used to replace the bulky Hammonds for band tours and club dates, jazz and blues keyboardists still tended to use vintage Hammonds for recordings, because the first clonewheel organs could not reproduce the tonal nuances of the old wooden Hammonds.
Currently, there are numerous B-3 "clones" on the market, which range from full-size, dual keyboard behemoths with real Leslie cabinets from Hammond Suzuki (which can cost over $10,000 US), to inexpensive Casio WK series home keyboards that have a digitally-recreated "tonewheel organ" function (which are available for less than $400 US). In between are numerous keyboard-based models from Hammond, Korg, Roland, Clavia (Nord Series), rack-mounted modules, and software-based "virtual synths" (such as the B4 by Native Instruments) which provide simulations of the B-3 sound. There is even a model by the Pari.E company which uses a modern version of the classic Hammond tonewheels, not a digital simulation.
The use of Hammond clones and the merits of using clones versus the vintage electromechanical Hammond is the subject of lively debate amongst musicians. The argument that digital simulations cannot recreate the complex interplay of variables that create the "Hammond sound" (tonewheel leakage, Leslie speaker rotation, etc.) is supported by a review of clones in Keyboard Magazine. The article, entitled "Clonewheel Heaven", reviewed electronic simulations of the traditional Hammond sound, and claimed that some aspects of the vintage electromechanical Hammonds' sound are not accurately reproduced by clones and emulation devices. Nevertheless, the increasing use of clonewheel organs on recordings by jazz and blues organ solo players is testimony to their sound and tone quality; it is also worth noting the wide variety of tonal variations that exist even among genuine vintage tonewheel Hammond organs. Owing to any number of causes — not least of which are the age of its components and the amount of use a tonewheel organ has had — variations in volume levels between tonewheels, varying levels of key click, and other tonal differences are more common than not.
Despite the widespread availability of relatively lower-cost, reliable digital "clones" and emulation devices, and the near-universal use of "clones" for band tours and club gigs, many jazz, blues and gospel keyboardists still have a strong interest in using vintage Hammond organs for studio recordings. Even if a clone is able to accurately reproduce the vintage electromechanical Hammond sound — several companies such as Clavia and Hammond Suzuki are making this claim — performers still have an affection for the look, feel, characteristics and heritage embodied in the much heavier, old wooden vintage instruments.
'''Note''': in the mid-1970s, their joint enterprise with Hammond called ''Nihon Hammond'' manufacture the several transistor Hammond organs in Japan and England, including Cadette VS-300 (after 1973), F1000/F2000/F3000, etc., according to ''[http://www.hammondclub.nl/nl/menu/Hammond/De_Hammond_Encyclopedie/A-K_series/F_series/F_1000-2000-3000_series Da Hammond Encyclopedia]''.
