Description
Frequency at which the low and high
ranges will be divided
Delay time from when the original
sound is heard to when the low-range
flanger sound is heard
When this is set to "note," the effect is
synchronized with the tempo.
Rate at which the low-range flanger
sound is modulated (Hz)
Rate at which the low-range flanger
sound is modulated (note)
Modulation depth for the low-range
flanger sound
Spaciousness of the low-range flanger
sound
Proportion of the low-range flanger
sound that is to be returned to the
input (negative values invert the
phase)
Delay time from when the original

flanger sound
Spaciousness of the high-range flanger
sound
Proportion of the high-range flanger
sound that is to be returned to the

Description
Type of filter
Lpf: The wah effect will be applied over
a wide frequency range.
Bpf: The wah effect will be applied over
a narrow frequency range.
Adjusts the center frequency at which
the effect is applied.
Adjusts the amount of the wah effect
that will occur in the range of the
center frequency.
Set a higher value for Q to narrow the
range to be affected.
Adjusts the sensitivity with which the
filter is controlled.
Sets the direction in which the
frequency will change when the auto-
wah filter is modulated.
Up: The filter will change toward a
higher frequency.
Down: The filter will change toward a
lower frequency.
When this is set to "note," the effect is
synchronized with the tempo.
Frequency of modulation (Hz)
Frequency of modulation (note)
Depth of modulation
Adjusts the degree of phase shift of the
left and right sounds when the wah
effect is applied.

● 012b: Ring Modulator
This is an effect that applies amplitude modulation (AM) to the input signal, producing bell-like
sounds. You can also change the modulation frequency in response to changes in the volume of
the sound sent into the effect.
