IMPORTANT

NOTES

In

addition

to

the

items

listed

under

“USING

THE

UNIT

SAFELY,”

please

read

and

observe

the

following:

.

Power

Supply

©

Before

connecting

this

unit

to

other

devices,

turn

off

the

power

to

all

units.

This

will

help

prevent

malfunc-

tions

and/or

damage

to

speakers

or

other

devices.

Placement

e

Using

the

unit

near

power

amplifiers

(or

other

equipment

containing

large

power

transformers)

may

induce

hum.

To

alleviate

the

problem,

change

the

orientation

of

this

unit;

or

move

it

farther

away

from

the

source

of

interference.

¢

Noise

may

be

produced

if

wireless

communications

devices,

such

as

cell

phones,

are

operated

in

the

vicinity

of

this

unit.

Such

noise

could

occur

when

receiving

or

initiating

a

call,

or

while

conversing.

Should

you

experience

such

problems,

you

should

relocate

such

wireless

devices

so

they

are

at

a

greater

distance

from

this

unit,

or

switch

them

off.

*

Do

not

expose

the

unit

to

direct

sunlight,

place

it

near

devices

that

radiate

heat,

leave

it

inside

an

enclosed

vehicle,

or

otherwise

subject

it

to

temper-

ature

extremes.

Excessive

heat

can

deform

or

discolor

the

unit.

e

When

moved

from

one

location

to

another

where

the

temperature

and/or

humidity

is

very

different,

water

droplets

(condensation)

may

form

inside

the

unit.

Damage

or

malfunction

may

result

if

you

attempt

to

use

the

unit

in

this

condition.

Therefore,

before

using

the

unit,

you

must

allow

it

to

stand

for

several

hours,

until

the

condensation

has

completely

evaporated.

Maintenance

¢

For

everyday

cleaning

wipe

the

unit

with

a

soft,

dry

cloth

or

one

that

has

been

slightly

dampened

with

water.

To

remove

stubborn

dirt,

use

a

cloth

impreg-

nated

with

a

mild,

non-abrasive

detergent.

After-

wards,

be

sure

to

wipe

the

unit

thoroughly

with

a

soft,

dry

cloth.

ə

Never

use

benzine,

thinners,

alcohol

or

solvents

of

any

kind,

to

avoid

the

possibility

of

discoloration

and/or

deformation.

Additional

Precautions

e

Use

a

reasonable

amount

of

care

when

using

the

unit’s

buttons,

sliders,

or

other

controls;

and

when

using

its

jacks

and

connectors.

Rough

handling

can

lead

to

malfunctions.

e

When

connecting

/

disconnecting

all

cables,

grasp

the

connector

itself—never

pull

on

the

cable.

This

-

way

you

will

avoid

causing

shorts,

or

damage

to

the

cable’s

internal

elements.

*

To

avoid

disturbing

your

neighbors,

try

to

keep

the

unit’s

volume

at

reasonable

levels.

You

may

prefer

to

use

headphones,

so

you

do

not

need

to

be

concerned

about

those

around

you

(especially

_-

when

it

is

late

at

night).

e

When

you

need

to

transport

the

unit,

package

it

in

the

box

(including

padding)

that

it

came

in,

if

possible.

Otherwise,

you

will

need

to

use

equiv-

alent

packaging

materials.

e

Use

a

cable

from

Roland

to

make

the

connection.

It

using

some

other

make

of

connection

cable,

please

note

the

following

precautions.

¢

Some

connection

cables

contain

resistors.

Do

not

use

cables

that

incorporate

resistors

for

connecting

to

this

unit.

The

use

of

such

cables

can

cause

the

sound

level

to

be

extremely

low,

or

impossible

to

“hear.

For

information

on

cable

specifications,

contact

the

manufacturer

of

the

Attaching

the

GK-3B

to

the

Bass

The

GK-3B

can

be

attached

to

and

used

with

conventional

electric

basses.

Please

read

the

following

precautions

before

installing

the

GK-3B.

Precautions

Before

Installing

Do

not

use

the

GK-3B

on

basses

with

doubled

strings

or

other

highly

customized

basses,

piccolo

basses

and

other

basses

with

unusual

tunings,

or

basses

with

other

non-metallic

core

strings.

The

pickup

may

not

function

properly

in

such

cases.

Make

any

adjustments

to

the

bass

neck,

string

height,

and

other

such

modifications

before

installing

the

GK-3B.

Try

placing

the

divided

pickup

and

the

controller

unit

on

the

bass

before

actually

attaching

them

to

confirm

that

there

will

be

no

problem

with

the

installation.

When

using

the

screw

to

attach

the

controller,

we

recommend

that

you

first

attach

the

GK-3B

temporarily

using

the

special

holder,

then

after

confirming

that

there

are

no

problems

when

actually

performing

with

the

unit,

secure

it

with

the

screw.

If

only

the

double-sided

tape

is

used

to

attach

the

controller,

shocks

from

rough

handling

during

performances

and

from

extended

use

will

cause

the

tape

to

deteriorate,

with

the

controller

shifting

out

of

position

as

a

result.

Also,

if

the

finish

on

your

bass

is

less

than

perfect,

you

may

discover

that

the

finish

is

also

removed

when

you

later

remove

the

tape.

The

supplied

tape

is

intended

to

be

used

only

very

temporarily,

to

help

you

determine

the

optimum

position

for

the

controller.

.

With

certain

basses,

the

space

between

the

pickup

at

the

bridge

position

and

the

bridge

itself

is

too

narrow

to

allow

installation

of

the

divided

pickup.

In

such

instances,

it

may

be

possible

to

attach

the

pickup

by

modifying

the

bass

(for

example,

by

moving

the

bridge

pickup

more

towards

the

neck

to

make

room

for

the

divided

pickup);

consult

your

bass

dealer.

When

attaching

the

GK-3B

to

the

bass,

you

should

try

to

orient

the

unit

so

no

buttons

or

controls

get

damaged,

and

handle

with

care

to

avoid

dropping

it,

or

allowing

it

to

fall

or

tip

over.

“B”

(1

“C”

(0.25

combine

these

as

necessary

to

the

The

that

the

between

the

and

the

is

approximately

1.5

mm

(0.6")

when

the

(p.

If

compensate

by

adding

the
