The Hammond Organ, first introduced in 1934, is a type of electric organ that uses electromagnetic technology to produce sound. Over the years, the Hammond Organ has become a beloved instrument among musicians across a variety of genres, from jazz to rock to gospel. While the term "Hammond Organ" is perhaps the most well-known descriptor for this instrument, there are a few other terms that are often used synonymously. These include "Hammond B-3," "Hammond C-3," and "Hammond A-100," each of which refers to a specific model of the Hammond Organ with slightly different features and capabilities.
