EFFECT Knob Settings 10

Pedal-Controlled Phaser
A phaser effect with its feedback controlled by the expression
pedal.
Tremolo
Varies the volume of the signal, creating a rising and falling effect.
Higher values result in greater depth of variation.
Pedal-Controlled Tremolo
A tremolo effect with its depth controlled by the expression pedal.
Ring Modulation
An effect that modulates the amplitude of the signal, giving it a
metallic sound. Higher values result in greater modulation depth.
Pedal-Controlled Ring Modulation
Ring modulation with its depth controlled by the expression pedal.
Cry
Creates an effect similar to that of a voice box, adding a human-like
crying effect to the sound. Higher values result in greater intensity.
Pedal-Controlled Cry
A cry effect with its filter frequency controlled by the expression
pedal.
Random Sample and Hold Step Filter
For this effect, the filter cutoff frequency changes abruptly to a
new psuedo-random value at a fixed time interval, producing an
arpeggiator-like sound.
Pedal-Controlled Step Filter
A step filter with its depth controlled by the expression pedal.
Slow Attack
Reduces the attack rate of the signal, slowing the rate at which the
volume of the sound rises when you attack a string. Higher values
result in higher sensitivity.
Auto Pan
Pans the signal back and forth from left to right at a constant rate
determined by the PARAM setting. Higher values result in
increased pan depth.

Flanger
Shifts the pitch of the signal up and down, creating a swirling
effect. Higher values result in longer delay.
Pedal-Controlled Flanger
A flanger with its delay controlled by the expression pedal.
Rotary Speaker
Emulates the sound of the classic rotary, creating a Doppler effect
similar to that achieved by an organ’s rotating speaker. Higher
values result in greater intensity and pan depth.
Pedal-Controlled Rotary Speaker
A rotary speaker effect with its intensity and pan depth controlled
by the expression pedal.
Chorus
Adds fullness to your sound by emulating a chorus of multiple
instruments. Higher values indicate greater modulation depth.
Pedal Chorus
A Chorus effect with its modulation depth controlled by the
expression pedal.
Pitch Transpose
Transposes the pitch of the signal either up or down. P0 – P4
transpose the pitch down a minor third, a major third, a perfect
fourth and a perfect fifth respectively. P5 – P9 transpose the pitch
up in the same manner.
Variable Pitch Transpose Up
Variably transposes the pitch upward from 0 to 2 octaves
according to the setting of the direct-control parameter (PARAM)
for FX1.
Variable Pitch Transpose Down
Variably transposes the pitch downward from 0 to 2 octaves
according to the setting of the direct-control parameter (PARAM)
for FX1.
Off
Turns off FX1.
