Main Features  
Achieves long delay times of up to 6.4 seconds. (*1) What’s more, up to 40 seconds of  
loop play—or “sound on sound”—is possible in HOLD mode.  
Multiple delay modes include “MODULATE,” which adds a chorus effect to the delay  
sound, and “ANALOG,” which models the classic BOSS DM-2 analog delay pedal.  
Features two new stereo modes in addition to 2-in/2-out true stereo connections.  
Provides stereo effects like “Panning” and “Effect + Direct.”  
Parameters can be controlled using an optional expression pedal (Roland EV-5).  
The delay time can be set in realtime by pressing an optional footswitch (FS-5U) or the  
built-in pedal to input the tempo.  
(*1) The delay time that can be set varies according to the mode.

1. AC Adaptor Jack  
1 2  
Accepts connection of an AC Adaptor (PSA-  
series; optional). By using an AC Adaptor,  
you can play without being concerned about  
how much battery power you have left.  
* If there are batteries in the unit while an AC  
adaptor is being used, normal operation will  
continue should the line voltage be interrupted  
(power blackout or power cord disconnection).  
* Use only the specified AC adaptor (PSA-series).  
* If the AC adaptor is connected while power is on,  
the power supply is drawn from the AC adaptor.

Panel Description  
* If this indicator goes dim or no longer lights  
while an effect is ON, or when the functions are  
indicated, the battery is near exhaustion and  
should be replaced immediately. For instructions  
on changing the batteries, refer to “Changing  
the Battery” (p. 22).  
4. INPUT-A (MONO) Jack  
INPUT-B Jack  
These jacks accept input signals (coming  
from a guitar, some other musical instru-  
ment, or another effects unit).  
* The CHECK indicator shows whether the effect  
is on or off, and indicates the different functions.  
It does not indicate whether the power to the  
device is on or not.  
* The unit’s functions differ according to how it is  
connected. Refer to “Setting the Output  
Method” (p. 16).  
* The INPUT-A (MONO) and INPUT-B jacks  
double as power switches. Power to the unit is  
turned on when you plug into the INPUT-A  
(MONO) or INPUT-B jack; the power is turned  
off when the cable is unplugged. Be sure to  
disconnect any cord plugged into the INPUT-A  
(MONO) or INPUT-B jack when not using this  
effects device.  
3. OUTPUT-A (MONO) Jack  
OUTPUT-B Jack  
The output jacks are used to connect the unit  
to an amplifier or another effects unit.  
* The unit’s functions differ according to how it is  
connected. Refer to “Setting the Output  
Method” (p. 16).  
5. TEMPO/EXP Jack  
This jack is for connecting an optional external  
footswitch (FS-5U) or an optional expression  
pedal (Roland EV-5).

the knob clockwise to increase the effect sound.  
When set at the three o’clock position, the effect  
is played at the same volume as the direct sound.  
7. Thumbscrew  
When this screw is loosened, the pedal will  
open, allowing you to change the battery.  
* For instructions on changing the battery, refer  
to “Changing the Battery” (p. 22).  
* When the E.LEVEL knob is set to MAX while in  
REVERSE mode, only the effect sound is  
output, with the effect sound at the same level as  
the input sound.

You can adjust the E.LEVEL knob setting  
to get two different kinds of effect, “Effect  
Sound + Direct Sound” and “Effect Sound  
Only.” Turning the E.LEVEL knob com-  
pletely to the right switches this to “Effect  
Sound Only.”  
HOLD:  
This records up to 40 seconds of a perfor-  
mance (when using monaural input),  
then plays it back repeatedly.

Connections  
* When running the unit on battery power, inserting a plug into the INPUT-A (MONO) or INPUT-B jack  
will automatically switch the unit on.  
* This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required  
before the unit will operate normally.  
* The use of an AC adaptor is recommended as the unit’s power consumption is relatively high. Should you  
prefer to use batteries, please use the alkaline type.  
* To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and  
turn off the power on all devices before making any connections.  
*
Some connection cables contain resistors. When connection cables with resistors are used, the sound level may be  
extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable.  
* If there are batteries in the unit while an AC adaptor is being used, normal operation will continue should  
the line voltage be interrupted (power blackout or power cord disconnection).  
* Once the connections have been completed (p. 9), turn on power to your various devices in the order  
specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to  
speakers and other devices.  
When powering up:  
When powering down:  
Turn on the power to your guitar amp last.  
Turn off the power to your guitar amp first.  
* When operating on battery power only, the unit’s indicator will become dim when battery power gets too  
low. Replace the battery as soon as possible.

Using the Tempo Delay  
* When an optional external footswitch (the FS-  
5U) is connected to the TEMPO/EXP jack, you  
won't be able to enter TEMPO mode by  
pressing the built-in pedal.  
Tempo input allows you to set the delay time to  
match the tempo of a song by repeatedly pressing  
the pedal switch in time with the desired tempo.  
You can also use this method to change the delay  
time to any setting you like as you perform.  
Using tempo input, the delay time can be set  
within the range of 0.2–3.2 seconds.  
3. Begin inputting the tempo  
Press the pedal switch in time with the  
song tempo (the CHECK indicator flashes red  
and green).  
*
With long delay, the maximum setting is 6.4 seconds.  
* The timing with which you press the pedal is  
converted to quarter-note beats.

Built-in Pedal  
1. Select the mode  
Use the MODE knob to select the mode to  
be used.  
* Tempo input cannot be used in HOLD mode.  
4. Finish inputting the tempo  
Hold down the pedal switch for at least  
two seconds to complete the setting (the  
CHECK indicator lights red).  
* The tempo may become confused momentarily  
when you go from Step 3 to Step 4.  
2. Switch to TEMPO mode  
Hold down the pedal switch for at least  
two seconds (the CHECK indicator lights

Control Using an Expression Pedal  
Connecting an expression pedal (Roland EV-  
5; optional) to the TEMPO/EXP jack enables  
you to control the respective parameters of  
the E.LEVEL, F.BACK, and D.TIME knobs.  
* Use only the specified expression pedal (Roland  
EV-5; optional). By connecting any other  
expression pedals, you risk causing malfunction  
and/or damage to the unit.  
2. Make the settings for the parameters  
Turn the E.LEVEL, F.BACK, and D.TIME  
knobs to set the maximum values of the  
ranges you want to control. If you don’t  
want to control a particular parameter  
with the expression pedal, set its value to  
the “MIN” position.  
* You can set only the maximum value of a  
parameter range controlled using the expression  
pedal. Setting the minimum value is not possible.

Changing the Battery  
When the indicator goes dim or no longer  
lights while the effect is on, it means that the  
battery must be replaced.

* The pedal can be opened without detaching the  
thumbscrew completely.  
Replace the battery following the steps below.

Setting Samples  
Reverse Playback Delay  
This delay gives an effect somewhat similar to reverse  
playback. It’s a sound that’s just a little out of the ordinary.  
Room Ambience Sound  
This delay simulates the sound that would be picked up  
by an ambience mic located on a stand within the room.  
Trick Sound  
Doubling  
This provides an effect similar to the sound of two  
guitars layered together.  
Employs repetitions of delayed sound to create an  
oscillating sound. Unique effects can be obtained by  
adjusting the D.TIME knob.  
*
Care should be taken, since this effect tends to  
increase the volume.
