MAD PROFESSOR - SNOW WHITE BASS AUTOWAH - OWNER’S MANUAL
Thank you for buying the
finest and most natural
sounding bass auto wah
pedal.
The SNOW WHITE BASS AUTO WAH
(SWBAW) circuit is based on a 1991 BJF
rack mount remote wah circuit and is
tuned like a real bass 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 filters. With
the four knobs you can have total control of
the effect.
SWBAW is tuned for bass and you can fine-
tune the pedal to suit your instrument, your
playing style and your taste of tone.
The controls are:
• SENSITIVITY: Sets the filter trigger level,
tune this carefully to fit your bass output and
your playing touch. You can further change
the sensitivity from your bass volume knob
while playing.
• BIAS: Controls the filter resonance
frequency. When Sensitivity is turned fully off
the Bias can be used as a sweepable filter.
• RESONANCE: Controls the sharpness or
Q-factor of the filter.
• D E C AY : Controls how fast the filter fre-
quency falls back to resting point (that is set
with the Bias control). This canbe 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 con-
trols and as this is a voltage control filter it
will react to your playing touch. The enve-
lope control circuit is carefully designed to
follow the dynamics of a bass and it might
take some time to master the Auto Wah
playing technics.
Try also adjusting your bass volume
between 8 and 10 to further expand use.
