UsErs GUIDE
Thank you for purchasing the
Soundblox Multiwave Distortion. The
Multiwave Distortion produces some
very unique distortion sounds and
does not attempt to model or emulate
any classic distortions. It offers some
new and different distortions ranging
from the more organic to synth-like
and octave heavy sounds. Like the
other Soundblox effects pedals,
the Multiwave Distortion is also

The Soundblox Multiwave Distor-
tion provides some unique distor-
tion sounds. In creating this effects
pedal, we didn’t intend to duplicate,
model, or emulate any existing types
of distortion. The types of algorithms
we use to create the distortion are
quite different from the standard set,
although with certain settings the
result can sound similar.
One of the techniques used is to
divide up the input guitar signal into
multiple frequency bands. Each band
is separately distorted, and then all
are recombined. If chords are played,
there can be a lot of clarity between
the various notes. It’s possible to
leave several notes droning, while a
melody is played on top. A normal
distortion tends to reduce such play-
ing to mush. Because of the multiple
bands, it’s also possible to get several
notes feeding back at the same time.
The first 14 settings (labeled
MULTI
BAND
) on the
EFFECT
knob use band
splitting while the last 7 (labeled
SINGLE
BAND
) do not.
The shape of the distortion mapping
curve is also different from standard
distortions. Normally, as the input
signal voltage rises, the output volt-
age also rises, but begins to level off
and finally pins (or clips) at a maxi-
mum value. With a foldback curve, for
large enough values of the input, the
output will begin to decrease. With
more extreme amounts of foldback,
after decreasing for a while, the
output can begin to increase again.
Maximum foldback has many regions
where the output alternates between
increasing and decreasing. These
kinds of curves add a lot of high fre-
quency content to the output. It also
can provide a lot of control over the
sound, based on the level of the input
signal. With foldback, chords contain-
ing only octaves and fifths tend to
sound best. Other intervals can cause
some strange, although not neces-
sarily undesirable sounds.
Using a special shape of the distor-
tion curve, strong second harmon-
ics can be created, sounding like a
note an octave higher. Rolling off the
guitar tone control will help maximize
the octave impression. Complex
chords don’t typically work well for
octave settings. The result is very
sensitive to the input signal level
(as long as the
SUSTAIN
and
DRIVE
controls are not set too high) and can
give a sort of auto-wah effect.
A conventional distortion effect tends
to turn the guitar signal into square
waves. Playing harder only makes
the transition from negative clipping
to positive clipping a little bit steeper.
With our foldback and octave algo-
rithms, a slightly higher input can
have a radical effect on the shape of
the output signal.

While the primary function of the
Multiwave Distortion is as a stand-
alone effects pedal you also have the
option of exploring some additional
functions by plugging in a Hot Hand
sensor. When a sensor is plugged in
the amount of
DRIVE
is controlled by
the Hot Hand sensor. The maximum
amount of drive you can get by mov-
ing the sensor is determined by the
position of the
DRIVE
knob.
Hot Hand Basics
The Hot Hand motion sensors are
sold separately and come in either
wired or wireless versions. Both will
work with the Multiwave Distortion.
Additionally, the
SENSOR
IN
jack will
be compatible with any future Source
Audio sensors.
The Hot Hand ring contains an accel-
erometer that responds to accelera-
tion and is not based on any type of
proximity to the guitar. By moving
your hand or by changing the position
of your hand you can modulate the
effect. For a good description of Hot
Hand Theory, download the Hot Hand
Motion Controlled Wah Filters manu-
al. It is available at www.sourceaudio.
net. Keep in mind that the Multiwave
Distortion can only use the x-axis of
the ring sensor. Please note that for
the Multiwave Distortion, the typical
Hot Hand control parameters can
NOT
be adjusted.
Calibration
The Multiwave Distortion has a
calibration feature which is only
used in Hot Hand mode. However,
calibration is not required before use.
The calibration feature allows you to
set the maximum point of the
DRIVE
sweep for any position of your hand.
Depending on your playing style, you
may find it useful to try some differ-
ent calibration positions. The most
common use is setting the calibration
with the sensor pointing up to make
raising your hand the maximum
end of the
DRIVE
sweep. Calibration
can also be useful if you are putting
the sensor on a headband or other
alternate locations.
To perform a calibration
•
Turn the
EFFECT
knob to the
CALIBRATE
position.
•
Hold the sensor in the desired
position.
•
While holding the sensor steady,
press the
ON/OFF
footswitch and
wait for 1 second.
•
Turn the
EFFECT
knob away from
calibrate to use your new calibra-
tion setting. Note: Calibration
settings will be saved between
power cycles.
•
If you have trouble with calibra-
tion and need to get back to the
default setting, run the calibration
procedure with your hand raised up
at a 45 degree angle.
