What is the Wheel Brake?
This simulates the way in which the tonewheels stop rotating
when you switch off the power on a tonewheel organ.
Since the amplifier of a tonewheel organ consisted of analog
circuits using vacuum tubes, it would continue to produce
sound for a short time even after the power was turned off.
However, since the organ’s tonewheels would start slowing
down as soon as the power was turned off, this would make
the pitch drop. The technique of stopping the tonewheels was
sometimes used on tonewheel organs. A skilled performer
could use this effect within their music.
What is a Ring Modulator?
This simulates a circuit that produces an unpitched metallic
sound by varying the frequency of the ring modulator’s
internal oscillator.
In hard rock of the past, some organ players applied aggressive
effects such as a ring modulator to their organ in order to
compete with the aggressive playing of the electric guitarist.
A ring modulator is an effect that generates complex overtones
that are not found in the original sound. These complex
overtones create a metallic-sounding resonance.
The word “ring” comes from the ring-shaped circuit that is
formed when a ring modulator is constructed using analog
components.
What is a Spring Reverb?
In the days when analog circuits were used, some reverb units
produced their reverb effects by using a spring. This was the
Spring Reverb. When physical impact is applied to a spring
reverb unit, the springs bounce against each other, producing
a distinctive clashing sound. Some performers used this sound
intentionally.
