TONE Knob
This knob controls the tone of the distortion sounds. Rotating the knob clockwise
cuts lower frequencies, creating sharp sounds.
Rotating the knob counterclockwise cuts higher frequencies, creating softer,
warmer sounds.
7 The DS-1 is an eect unit that generates both distortion and sustain eects.
7 By rotating the knobs you can create all kinds of sounds, from warm, soft sustain to hard, powerful distortion.
7 The DS-1 can be powered by a battery or an optional AC adaptor.
OUTPUT Jack
The output jack is used to connect the unit to
ampliers or other devices.
Guitar Amplier
DIST Knob
This knob controls the depth of distortion sounds and the length of sustained
sounds.
Rotating the knob clockwise creates deeper distortion and a longer sustain time.
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.
* Use only the specied AC adaptor (PSA-Series).
* Use only the speci ed AC adaptor (PSA series; sold separately), and connect it to an AC outlet of the
correct voltage. Do not use any other AC adaptor, since this may cause malfunction.
* 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.
CHECK Indicator
This indicator shows whether an eect is ON/OFF, and also 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. For instructions on changing the battery,
refer to “Changing the Battery.”
LEVEL Knob
This knob adjusts the level of the eect sounds. Set the knob so there is no
volume dierence between the eect and straight guitar sounds.
Pedal Switch
Used for switching eects on/o.
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.”

Use of Battery
5
A battery was installed in the unit before it left the factory. The life
of this battery may be limited, however, since its primary purpose
was to enable testing.
5
If the batteries run extremely low, the sound may distort, but this
does not indicate a malfunction. If this occurs, please replace the
batteries / use the optional AC adaptor.

Before turning the unit on/o, always be sure to turn the volume
down. Even with the volume turned down, you might hear some
sound when switching the unit on/o. 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.
