Feedback
-99% to +99%
Controls the amount of feedback applied to the phaser. Positive or
negative values will impart a different tonality to the phaser effect,
either accenting the peaks or the notches.

Description
Pre HPF Fc
10Hz to 1.50kHz
Filters out the low frequencies before the EQ. The higher the value, the
less low frequencies will pass through.
Pre VCF Fc
10Hz to 7.10kHz
Determines the distortion filter cut off frequency. Higher values have a
brighter sound. This parameter can be modulated, using a CV Pedal for
a wah wah pedal effect.
Pre VCF Q
1.0 to 40.0
Determines the level and width of the resonant peak at the filter cutoff
point. While the Fc (filter cutoff) parameter determines where (at what
frequency) this peak will occur, the Q setting controls the
height
of the
peak. This setting is important for the auto-wah effect.
PreVCF EnvAmt
-99% to +99%
Determines how much the amplitude of the incoming signal will modify
the distortion filter cutoff frequency. When set to 0, no modification will
occur. When set to mid positive values, the Pre-VCF Fc will go high,
but then come down to its nominal setting. When set to negative mid
values, the Pre-VCF Fc will go low, and then go back up to its nominal
setting. How quickly it does so is determined by the Attack and Release
parameters. This sound is the auto-wah; positive values will boost the
high frequencies, offering an “oww-oww” sound, and negative values
will cut the high frequencies, producing a “dweep-dweep” sound.
Dist Gain
Off, -49.5dB to +48dB
Controls the gain going into the distortion effect. This will boost the
signal level up to 48 dB. For more distortion, use a high input level gain
and turn the Distortion Volume down to keep the volume under control.
For less distortion, use a low gain input level and a higher output
volume.
Dist Volume
Off, -49.5dB to 0.0dB
Controls the volume of the distortion effect. Generally, if the Distortion
Gain is set high, set this parameter lower.
Distortion
Off, On
Chooses between distorted and clean signals.
Post VCF Fc
10Hz to 7.10kHz
This parameter is used to control the second VCF that exists after the
distortion.
Post VCF Q
1.0 to 40.0
This parameter is used to control the second VCF that exists after the
distortion.
PostVCF EnvAmt
-99% to +99%
This parameter is used to control the second VCF that exists after the
distortion.
VCF Attack
50us to 100ms
Sets the attack of the envelope follower (i.e. determines how closely the
attack is followed) once the incoming signal has been detected.
Generally the attack should be short.
