What organ did the Beatles use on Tomorrow Never Knows?

The Beatles used a Hammond RT-3 transistor organ on 'Tomorrow Never Knows.' This was a solid-state Hammond model from the mid-1960s that had a brighter, more aggressive tone than the classic tube-driven B-3.

How did the Beatles get the swirling organ sound on Tomorrow Never Knows?

The swirling effect was created by running the Hammond RT-3 organ through a Leslie 147 rotating speaker cabinet. The Leslie's spinning horn and drum create doppler effects that produce the characteristic tremolo and vibrato modulation heard on the track.

What is a Leslie 147 speaker cabinet?

The Leslie 147 is a rotating speaker cabinet designed for Hammond organs, featuring a rotating horn for treble frequencies and a rotating drum for bass frequencies. The spinning creates pitch and amplitude modulation effects that became synonymous with psychedelic rock.

How to recreate Beatles Tomorrow Never Knows organ tone?

Start with a Hammond organ sound (preferably transistor-based like the RT-3), then add Leslie rotary speaker simulation. Set the Leslie to a medium-slow speed and ensure stereo separation to capture the spatial movement of the rotating speakers.

What microphone was used to record Tomorrow Never Knows organ?

An AKG C12 tube condenser microphone was used to capture the Leslie cabinet at Abbey Road Studios. The C12's smooth frequency response was well-suited to capturing the complex harmonics and spatial movement of the rotating speakers.

The Story

The organ sound on 'Tomorrow Never Knows' was created using a Hammond RT-3 organ played through a Leslie 147 rotating speaker cabinet. The distinctive swirling effect comes from the Leslie's rotating horn and drum, which creates doppler-shifted pitch and amplitude modulation. The setup was recorded at Abbey Road Studios with an AKG C12 microphone, capturing the full spatial movement of the rotating speakers that became integral to the psychedelic sound.
