Hammond B-3 organ (electromechanical)

After the piano, no other keyboard instrument has been used in more musical recordings than the Hammond B-3 organ. First designed in 1954 as a low-cost alternative to the acoustic church organ, the instrument enjoyed immense popularity in almost every genre of music, from jazz to funk to prog rock. Often paired with the Leslie 122 tone cabinet, the B-3’s distinctive and versatile sound can be heard on countless classic songs, including The Zombies’ “Time of the Season,” The Beatles’ “Let It Be” and Bob Dylan’s “Like a Rolling Stone.”
