FILTER
Parameter Value Explanation
TYPE
Selects the type of wah eect and lter.
A-WAH G
Automatically produces a wah eect by cyclically modulating the lter
(for guitar).
A-WAH B Automatically produces a wah eect by cyclically modulating the lter (for bass).
T-WAH G
Produces a wah eect by modulating the lter according to the volume of the
input signal (for guitar).
T-WAH B
Produces a wah eect by modulating the lter according to the volume of the
input signal (for bass).
PATTERN Lets you freely program how the lter changes.
A-WAH G, A-WAH B
RATE 0.01–20.00 Hz Adjusts the rate of the wah.
BPM 6.0–600.0
Species the tempo.
The range of this setting depends on the RATE or NOTE value.
NOTE
`
–
Œ
Adjusts the rate of the wah, specied as a note value relative to the BPM.
FILTER MODE
Selects the wah mode.
LPF Low pass lter. Passes only the low-frequency region.
HPF High pass lter. Passes only the high-frequency region.
BPF Band pass lter. Passes only the specied frequency region.
DEPTH 0–100 Adjusts the wah depth.
FREQUENCY 0–100 Adjusts the center frequency of the wah eect.
RESONANCE 0–100
Adjusts how the wah eect is applied in the region of the center frequency.
Higher values boost the lter eect, producing a strongly distinctive character. A
value of “50” produces the typical wah sound.

the POLARITY setting. Higher values increase the response; with a setting of “0,”
the wah eect does not respond to your picking.
FREQUENCY 0–100 Adjusts the center frequency of the wah eect.
RESONANCE 0–100 Adjusts how the wah eect is applied in the region of the center frequency.
DECAY 0–100 Adjusts the rate at which the lter is moved.
