the POST FILTER.
LOW GAIN -15–+15 dB
Adjusts the gain of the low
range.
HIGH GAIN -15–+15 dB

01:SINGLE A simple monaural delay.
02: PAN
Provides a tap delay eect that divides
the delay time between the left and
right channels.
03: REVERSE
Produces the eect of playback in
reverse.
04: ANALOG Produces a mild analog delay sound.
05: TAPE
This setting provides the characteristic
wavering sound of a tape echo.
06:
MODULATE
A delay with a pleasant amount of
modulation added.
07: HICUT
Produces a warm-sounding delay with
the high frequencies attenuated.
DELAY

BPM
Adjusts the delay time.
FEEDBACK

0–100
Adjusts the number of repetitions for
the delay.
EFFECT
LEVEL
0–120 Adjusts the volume level of the eect.
SEND
MFX SEND 0–100
Adjusts the volume of the signal sent
from the MFX output to DELAY.
MOD
SEND
0–100
Adjusts the volume of the signal sent
from the AMP-MOD output to DELAY.
BYPASS
SEND
0–100

from the bypass channel (unprocessed
by the eect) to DELAY.
REVERB
Group Parameter Value Description
TYPE
SWITCH OFF, ON Turns the REVERB OFF/ON.
TYPE
Use this to choose the type of reverb.
01:
AMBIENCE
Simulates an ambience microphone (o-
mic, placed at a distance from the sound
source) used in recording and other
applications. Rather than emphasizing
the reverberation, this reverb is used to
produce a sense of openness and depth.
02: ROOM
Simulates the reverberation of a small
room. Provides warm reverberations.
03: HALL 1
Simulates the reverberation of a concert
hall. Provides clear and spacious
reverberations.
04: HALL 2
Simulates the reverberation of a concert
hall. Provides mild reverberations.
05: PLATE
Simulates plate reverberation (a studio
eect unit that uses the vibration
of a large metal plate to produce
reverberation). Provides a metallic sound
with a distinct upper range.
REVERB
TIME #
0.1 s–10.0 s
Adjusts the length (time) of
reverberation.
HIGH
CUT #
700 Hz–
11.0 kHz,
FLAT
The high cut lter adjusts the amount
of high frequencies in the reverb sound.
When FLAT is selected, the high cut lter
will have no eect.
EFFECT
LEVEL
0–100 Adjusts the volume level of the eect.
