EFFECTS SECTION
STEREO FUZZ
The Stereo Fuzz introduces a controlled
distortion to any signal passing through
it. Distortion creates harmonics by
clipping the top of the wave when it
exceeds a certain level. Sine waves are
transformed into square waves and
complex waves take on noise-like quali-
ties. There are two types of fuzz in Classic
Keys: Fuzz and Fuzz Lite.
FUZZ
This Fuzz is probably the “grungiest” fuzz
you have ever heard. Two filters, one at
the input and one at the output of the
fuzz, allow you to control the amount and
type of harmonics added to the sound.
The
Input Filter controls the amount of
harmonics produced by the fuzz and the
Output Filter removes harmonics at the
output, smoothing the sound. Higher
values allow more harmonics to pass. The
level of the input sound greatly affects the
amount of fuzz, so that Classic Keys’
envelopes can now control harmonic
content as well as the volume.
Output
Volume sets the output level of the fuzz.
There are two complete fuzz effects,
controlled by the same set of controls as
shown in the diagram below.
Two independent sounds can be pro-
cessed by panning primary and secondary
to opposite sides, or a single sound can be
routed through both sides. If a single
sound is panned slightly off center, the
fuzz will act slightly differently on each
side because of the difference in level.
FUZZ LITE
This is a more restrained type of fuzz
utilizing “soft-clipping.” As the level
increases, the waveform through Fuzz
Lite becomes somewhat squared. As
signal level is increased further, it trans-
forms into a square wave. There is no
Output Volume control on Fuzz Lite.
Experiment with the way the input and
output filters work on the sound. Fuzz is
a specialized effect, not for every situa-
tion, but another powerful tool in your
musical arsenal.
