EFFECT SECTION
EFFECTS AND PARAMETERS
EQUALIZER
EQ HIGH FREQUENCY (HIGH F)
Range: 500 Hz ~ 12.0 kHz
Determines the cutoff frequency of the high
frequency band (as adjusted in High above).
EQ OUTPUTRange: 0 ~ 200%
Determines the level of the processed sound.
Settings above 100% are used for boosting the
signal to an appropriate level to compensate for
equalizer adjustments that bring the overall
signal level down.
Amp Simulator + EQ (AEQ)
This effect realistically reproduces the characteris-
tic sound of a guitar amplifier, and provides a
natural sound for direct recording purposes when
not using an external amplifier. A separate two-
band parametric equalizer is included after the
Amp Simulator effect.
TYPESettings: Stack, Combo, Tube
Determines the type of amplifier that is simu-
lated. Stack recreates the powerful sound of a
huge amp/speaker setup, Combo recreates a
compact amp cabinet, and Tube recreates the
warm sound of a tube amplifier.
EQ LOWRange: –15 ~ +15 dB
Determines the amount of boost or cut applied
to the low frequencies (as set in Low Frequency
below).
Note: This parameter is for adjusting the low
gain of the two-band EQ, which is
independent of the Amp Simulator effect.
EQ HIGHRange: –15 ~ +15 dB
Determines the amount of boost or cut applied
to the high frequencies (as set in High Fre-
quency below).
SPEED (controlled with the second knob from the
left, when Auto is selected) —
Range: 0.4 ~ 6.4 Hz
Determines the speed of the filter sweep cycle.
CENTER FREQUENCY (CENTER)
Range: 125 Hz ~ 9.0 kHz
Determines the center frequency of the Wah
effect. The emphasized frequency is swept
around this frequency.
RANGERange: 0 ~ 28
Determines the width of the center frequency,
or how far the sweep extends above and below
the center frequency. (See illustration above.)
Sub parameters:
FEEDBACK (FB)Range: 0 ~ 100%
Determines the amount of the Wah-processed
signal that is fed back to the Wah input. Higher
values result in a stronger Wah sound.
EQ INPUTRange: 0 ~ 100%
Determines the level of the input signal. Nor-
mally, this should be set to 100%; however, if
equalizer adjustments have been made that
bring the overall signal level up, lower values
can be used here to compensate to reduce the
volume to an appropriate level.
EQ LOWRange: –15 ~ +15 dB
Determines the amount of boost or cut applied
to the low frequencies (as set in Low Frequency
below).
EQ LOW FREQUENCY (LOW F)
Range: 40 Hz ~ 1.2 kHz
Determines the cutoff frequency of the low
frequency band (as adjusted in Low above).
EQ HIGHRange: –15 ~ +15 dB
Determines the amount of boost or cut applied
to the high frequencies (as set in High Fre-
quency below).
