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 qualities. There are two types of fuzz in
UltraProteus: 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 UltraProteus' 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 processed 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 transforms 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 situation, but another powerful tool in your
arsenal.
