AIR
Simulates the ambient character of sound picked up with a
microphone. Higher values result in greater simulated distance
between the guitar and the microphone.
oF
Sets the AIR parameter to OFF.
EFFECT
Allows choosing one out of eight different effects that shape the
sound in various ways. The effect intensity can also be adjusted.
RICH CHORUS
Generates a deep, rich sounding chorus. Higher values result in
stronger chorus effect.
PEDAL RICH CHORUS
Allows using the expression pedal (FP01/FP02) connected to
the CONTROL IN jack to adjust the mixing ratio of the RICH
CHORUS effect.
LIGHT CHORUS
Generates a light chorus with soft modulation. Higher values result
in stronger chorus effect.
PEDAL LIGHT CHORUS
Allows using the expression pedal (FP01/FP02) connected to
the CONTROL IN jack to adjust the mixing ratio of the LIGHT
CHORUS effect.
12-STRING
Produces an effect resembling the sound of a 12-string guitar. Larger
values result in a stronger effect.
PEDAL 12-STRING
Allows using the expression pedal (FP01/FP02) connected to the
CONTROL IN jack to adjust the intensity of the 12-STRING effect.

DOUBLING
Creates a doubling effect like two players playing the same tune with
a slight shift. Higher values result in larger shift between original
sound and effect sound.
PEDAL DOUBLING
Allows using the expression pedal (FP01/FP02) connected to the
CONTROL IN jack to adjust the intensity of the DOUBLING effect.
TOUCH
This effect aligns the picking touch. Higher values result in distinct
notes even with soft picking.
PEDAL TOUCH
Allows using the expression pedal (FP01/FP02) connected to
the CONTROL IN jack to adjust the intensity of the TOUCH effect.
EMPHASIZER
This effect adds higher harmonics to emphasize the sound character.
Higher values result in more dazzling sound.
PEDAL EMPHASIZER
Allows using the expression pedal (FP01/FP02) connected to the
CONTROL IN jack to adjust the intensity of the EMPHASIZER effect.
DRY MIX
Mixes the original guitar sound to the signal after passing the AIR
parameter. Lower values result in stronger AIR parameter influence
and higher values result in stronger original sound.

PEDAL DRY MIX
Allows using the expression pedal (FP01/FP02) connected to
the CONTROL IN jack to adjust the mixing balance between the
signal after passing the AIR parameter and the original sound.
The actual sound that will be produced by this effect depends on
the settings made for the various parameters before the AIR
parameter. If the sound after the AIR parameter and the original
sound is not very different, the effect will be weak.
