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 fine­tune the pedal to suit your instrument, your
playing style and your taste of tone.

The controls are:

• SE NS ITIVITY: 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.

• RE SONANCE: 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 con­trols and as this is a voltage control filter it
will react to your playing touch. The enve­lope 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.
