Panel Descriptions
Main Features
AC Adaptor
(PSA series; sold separately)
Electric Guitar
LEVEL knob
This adjusts the volume of the eect sound.
OUTPUT jack
Connect an amplier to this jack.
Guitar Amplier
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.
* 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 specied AC adaptor (PSA-series).
CHECK indicator
This indicator shows whether an eect is ON/OFF, and doubles as the Battery Check
indicator.
The indicator lights when an eect is ON.
* If this indicator goes dim or no longer lights while an eect is ON, the battery is near
exhaustion and should be replaced immediately.
TONE knob
This adjusts the tone.
Rotating the knob counterclockwise makes the sound milder, while
rotating in clockwise makes the sound sharper.
Pedal Switch
This switch turns the eects ON/OFF.
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.”
DRIVE knob
This adjusts the amount of overdrive.
Rotating it clockwise increases the eect, whereas counterclockwise
rotation reduces the eect.

sound when switching the unit on/o. However, this is normal and
does not indicate a malfunction.
Use of Battery
5
A battery is supplied with the unit. The life of this battery may be
limited, however, since its primary purpose was to enable testing.
5
If you handle batteries improperly, you risk explosion and uid
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).
5
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.
5
Batteries should always be installed or replaced before connecting
any other devices. This way, you can prevent malfunction and
damage.
