MAD PROFESSOR - SNOW WHITE AUTOWAH - OWNER’S MANUAL
Thank you for buying the
fi nest and most natural
sounding auto wah pedal!
The SNOW WHITE AUTOWAH (SWAW)
circuit is based on a 1991 BJF rack
mount remote wah circuit and is tuned
like a real wah.
The circuit was redesigned with envelope
controls and build into small size pedal. It
has very fast tracking and accuracy rarely
found on auto wahs/envelope fi lters. With
the four knobs you can have total control of
the effect.
You can fi ne-tune the SWAW to suit your
instrument, your playing style and your taste
of tone.
The controls are:
• SE NS ITIVITY sets the fi lter trigger level,
tune this carefully to fi t your guitar/bass
output and your playing touch. You can
further change the sensitivity from
your guitar volume knob while playing.
• BIAS controls the fi lter resonance
frequency. When Sensitivity is turned fully off
the Bias can be used as a sweepable fi lter.
• RE SONANCE controls the sharpness or
Q-factor of the fi lter.
• D E C AY controls how fast the fi lter
frequency falls back to resting point (that is
set with the Bias control). This can be set
fast (CW) so you get the wah effect on
every note or slow for a more traditional
auto wah sound.
PLAYING:
Please take time to get used to the controls and as this is a voltage control fi lter it
will react to your playing touch. The envelope control circuit is carefully designed to
follow the dynamics of guitar/bass and it
might take some time to master the Auto
Wah playing technics.
Try also adjusting guitar volume between
8 and 10 to further expand use.
C A U T I O N !
Never operate the unit with its bottom
removed or damage will most likely occur.
POWER REQUIREMENTS:
