All About Jazz have reviewed The Hammond Organ: Beauty in the B:
Vail includes enough technical information about the development of the HammondÃ¢â‚¬â„¢s electrical engineeringÃ¢â‚¬â€shunting resistors, lowpass filters, inductor-capacitors, etc & etcÃ¢â‚¬â€to satisfy even the most hard-core techno-geek, and more than enough to make the eyes of many other readers glaze over somewhat. Thankfully, most of it is dumbed-down into laypersonÃ¢â‚¬â„¢s language. For example, readers learn (if they didnÃ¢â‚¬â„¢t already know) the difference between tremolo (a pulsation of loudness) and vibrato (a rapid variation in pitch). The what and the why of the Ã¢â‚¬Å“chorusÃ¢â‚¬? effect (or what synthesizer players now call Ã¢â‚¬Å“detuneÃ¢â‚¬?) is also explained; a blending of slightly flat and sharp tones, it was a necessary retrofit because the musical tones produced by Hammond, designed as a cheap replacement for the pipe organ, were too Ã¢â‚¬Å“perfect.Ã¢â‚¬?
Other distinctive features of the inimitable Hammond sound, including loudness robbing, key click, percussion and spring reverb, are also explained in accessible terminology.
