Internal Design
● Wah
A wah effect dynamically changes the frequency character-
istic of a filter in order to produce a highly unique filter-
sweep sound. Auto wah changes the frequency in a cyclic
manner using an LFO, while touch wah performs filter
sweeps in response to the volume of the input signal.
● Reverb
Reverb effects model the complex reverberation produced
by sounds within enclosed spaces. In this way, they add a
natural-sounding sustain, which produces a feeling of
depth and space. Furthermore, different types of reverb –
such as hall, room, plate, and stage – can be used to simu-
late the sound of acoustic environments of varying sizes
and constructions.
● Chorus
Chorus reproduces the sound of multiple instruments play-
ing in unison for a thicker, deeper tone. As all instruments
differ slightly from each other in terms of pitch and phase,
their playing together produces an overall sound that is
warmer and more spacious. In order to reproduce this type
of behavior, chorus effects make use of delay. Specifically,
a delayed, second version of the original signal is produced
and given a vibrato-type effect by varying its delay time
over a period of approximately one second using an LFO.
When this second version is mixed back into the original
signal, the resulting tone sounds as if multiple instruments
are being played in unison.
● Tremolo & Rotary
Tremolo effects are characterized by the way in which they
modulate volume in a cyclical fashion. An auto-pan effect,
meanwhile, moves the sound from left to right in a similar
cyclical manner, and a rotary speaker effect simulates the
distinctive vibrato of rotary-type speakers often used with
organs. In a rotary speaker, the horn and rotor are spun in
order to create highly unique sounds using the Doppler
Effect.
