Installing Batteries

Insert the included batteries as shown in figure, being careful to orient the batteries correctly.

fig.02

• When turning the unit upside-down, get a bunch of newspapers or magazines,

and place them under the four corners or at both ends to prevent damage to

controls. Also, you should try to orient the unit so no controls get damaged.

• When turning the unit upside-down, handle with care to avoid dropping it, or

allowing it to fall or tip over.

• Make sure the “+” and “-” ends of the batteries are oriented correctly.

• When the batteries run down, the POWER indicator gets dim. If this happens,

replace with new batteries.

• When replacing the batteries, use six AA type.

• Do not mix fresh batteries with used ones, or mix batteries of different types.

Doing so can result in fluid leakage.

• Battery life can vary depending on battery type.

Continuous usage time under battery power is about 6 hours with alkaline

batteries and about 2 hours with carbon batteries. (This may vary according

to usage conditions.)

Making the Connections

About the GK-2A

To use the WP-20G with a guitar equipped with the GK-2A (or other GK-

compatible guitar), you will need an optional GK cable.

Refer to the GK-2A Owner’s Manual for instructions on installing the GK-2A.

S1/S2 Switch

The GK-2A’s S1/S2 switches correspond to this unit’s MASTER On/Off pedal

and Effects On/Off pedal, respectively.

Selection Switch

Set to the “MIX” position.

Note that this unit processes tones using the instrument’s divided pickup

signal (signal output when SYNTH is selected).

No sound is produced when the following settings are combined.

SYNTH VOL Knob

Controls the volume when MASTER ON is selected.

Making the Connections

• To get the best performance from the instrument, set your amp to “Clean” (no

distortion).

• When connecting the instrument to a guitar amp, make the necessary adjustments

to get the most suitable tone. When recording direct, use this with a COSM amp

(GT-3, GP-20 etc.).

• When connecting a GK cable, insert the cable completely until the connector is

securely locked. When disconnecting, press the connector’s lock while you detach

the cable.

* Always turn the amp volume down completely before connecting and disconnecting cords.

* 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.

* 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).

Turning On the Power

Be sure to observe the following order when connecting devices and 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.

➝

Connect the Amp

➝

Turn On Amp Power

* When the unit is running on battery power, the power comes on when you insert the connector

plug into the OUTPUT jack.

* Always make sure to have the volume level turned down before switching on power. Even with

the volume all the way down, you may still hear some sound when the power is switched on,

but 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.

GUITAR RETURN Jack

This is an input jack for

connecting another effects

device, electric guitar, or

other instrument.

When connected to this

jack, you can use sounds

other than the normal

pickup when Master is off,

and for the Mix sounds

when Master is on.

(refer to p.11, 12)

OUTPUT Jack

This jack is for connection to a guitar

amp, another effects processor.

* The OUTPUT jack also doubles

as the power switch when the

unit is running on battery

power. The power comes on

when a plug is inserted into the

INPUT jack, and goes off when

it is unplugged. Unplug any

connected cords when the unit

is not in use.

AC ADAPTOR Jack

This jack is for connecting an

AC adapter (BOSS PSA-series,

sold separately).

Using an AC adapter makes

possible long performances

with no worry about batteries

going dead.

GK IN Connector

This connector is for connecting

your guitar with a GK cable.

NORMAL PU MIX Switch

When Master is on, this switch determines

whether or not the normal pickup sounds (or the

sounds input to the GUITAR RETURN) are mixed.

By mixing the normal pickup sound,

you can create a sound that makes

your guitar sound come alive.

GUITAR OUT Jack

Normal pickup signals input

through the GK-2Aare output.

When a cable is

connected to this jack,

the output of the

normal pickup from the

OUTPUT jack stops.
