1. DC IN jack
Accepts connection of an AC Adaptor (PSA series; sold
separately). By using an AC Adaptor, you can play without being
concerned about how much battery power you have left.
* As soon as you connect the AC adaptor, the unit is turned on.
* We recommend that you keep batteries installed in the unit
even though you’ll be powering it with the AC adaptor. That
way, you’ll be able to continue a performance even if the cord
of the AC adaptor gets accidently disconnected from the unit.
* Use only the specified AC adaptor (PSA-series).
2. CHECK indicator
Combination indicator that shows the effect’s on/off status,
tempo (in Tempo mode: p. 10), and Battery Check function.
The indicator lights when an effect is ON.
* If this indicator goes dim or no longer lights while an effect
is ON, the battery is near exhaustion and should be replaced
immediately.
* The CHECK indicator shows whether the effect is being
applied or not, and is used to indicate other effects. It does
not indicate whether the power to the device is on or not.
3. OUTPUT jack
This output jack is connected to an amplifier or other effects
device.
4. EXP/CTL jacks
This jack lets you connect an expression pedal made by Roland/
BOSS, or a foot switch.
This allows you to attain pedal wah and Humanizer effects. It
also allows setting of the tempo (while in Tempo mode: p. 10).
* For more information and instructions, refer to“Description of
Each Mode”(p. 8) and “Using the EXP/CTL Jack” (p. 12).
5. GUITAR IN jack
This jack accepts input signals coming from a guitar, some other
musical instrument, or another effects unit.

* Inserting a plug into the GUITAR IN or BASS IN Jack will automatically switch the unit on.
* The use of an AC adaptor is recommended as the unit’s power consumption is relatively high.
* If operating this unit on batteries, please use alkaline batteries.
* To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any
connections.
* We recommend that you keep batteries installed in the unit even though you’ll be powering it with the AC adaptor. That way, you’ll
be able to continue a performance even if the cord of the AC adaptor gets accidentally disconnected from the unit.
* Use only the specified expression pedal. By connecting any other expression pedals, you risk causing malfunction and/or damage to
the unit.
* Once you've gotten hooked up correctly (p. 6), be sure to observe the following order when switching on the power to your
equipment. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices.
When powering up: Turn on the power to your guitar amp last.
When powering down: Turn off the power to your guitar amp first.
* Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some
sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.
* 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.
* If you handle batteries improperly, you risk explosion and fluid leakage. Make sure that you carefully observe all of the items related
to batteries that are listed in“USING THE UNIT SAFELY” and“IMPORTANT NOTES”(supplied on a separate sheet).

tempo is at 500 msec.
* To allow switching without the normal stress of dealing with
effect on/off hassles, when you go into the tempo setting
mode with the effect on, the effect is switched off for two
seconds, after which the AW-3 switches to the tempo setting
mode.
2. Depress the pedal to get the tempo you want.
The speed changes to match the tempo entered by pressing the
pedal, and the CHECK indicator will flash in sync with the tempo.
Available range for the tempo: 200 msec–4 sec
