I agree with that with a bemol. The Hammond B3 was a polyphonic synth,
but with a very unique sound. The combination of vacuum tubes, an
additive synthesis of waveforms from harmonic series made by mechanical
tonewheels that rotate in front of electromagnetic pickups, and a
leslie speaker make the sound of this organ very unique.
Due to the electro-mechanical nature of the frequencies generation, the
ratio between the frequencies was constant, but they was not exact
harmonics. Due to the vacuum tubes and the pickups, it was possible to
make some very weird effects like larsen.
Also, the keyboards and the contacts (a lot of them) was of outstanding
quality. It was 2 motors to entrain the electro-mechanical generator,
one asynchronous for the start-up, and one synchronous in order to keep
a constant tuning. It was also possible to stop the synchronous motor
and use the asynchronous one instead.
Bristol give us a very good approximation of this organ. But well, the
real thing is still something else, something like a mix of an organ
and a wild electric guitar. See Emerson, Lake & Palmer
- Live Broadcasts... Collector's Rarities
For the full potential of this organ :) go around 7:30 and 21:30.
