Midrange

Boost

The

Midrange

Boost

Control

allows

you

to

increase

the

midrange

response

of

the

guitar.

By

turning

the

knob

clockwise,

you

gradually

boost

the

midrange

and

bass

frequencies

as

you

decrease

the

treble

frequencies.

You

can

actually

shape

the

sound

of

the

pickups.

Caution:

At

maximum

setting,

the

volume

increase

is

approximately

25

dB

in

the

low

-mid

range,

so

the

output

of

your

instrument

could

be

substantially

more

powerful

than

that

of

a

standard

guitar

or

bass.

Notch

Filter

Frequency

Shift

The

active

electronic

circuitry

is

controlled

by

a

three-way

on

-board

switch,

and

offers

three

modes:

Passive

(standard

tone

control),

Narrow

Frequency

Band

Notch

Filter,

and

Wide

Band

Notch

Filter.

This

circuit

acts

quite

differently

from

the

normal

"boost"

circuit

that

is

usually

available

on

instruments.

The

Notch

Filter

takes

a

particular

frequency

of

the

bass

and

cuts

that

frequency,

thereby

emphasizing

the

remaining

frequencies

and

creating

a

unique

tone.

With

the

Frequency

Shift

Control,

the

center

of

the

"notch"

can

range

anywhere

from

100

Hz

to

10,000

Hz.

This

circuit

also

offers

two

different

notch

configurations,

one

that

cuts

a

very

narrow

band

of

frequen-

cies,

and

one

that

cuts

a

wider

band

of

frequencies.

Both

are

tuneable

with

the

Frequency

Shift

Control.

In

the

Passive

position,

the

Frequency

Shift

Control

is

inoperative.

Note:

As

you

turn

the

Frequency

Shift

Control

from

1

to

10,

the

notch

moves

from

high

frequencies

to

low

frequencies

—therefore

the

tone

you

hear

does

the

opposite.

In

other

words,

moving

the

Frequency

Shift

Control

from

1

to

10

causes

the

tone

you

hear

to

go

from

bass

to

treble.

SWITCHES

Pickup

Selector

The

pickup

selector

switch

does

just

what

it

implies,

it

selects

the

pickups

either

alone

or

in

combination.

Dual

pickup

models

are

supplied

with

a

three

position

switch,

while

the

three

pickup

models

are

equipped

with

a

five

position

switch.

Note:

Some

reissue

models

are

equipped

with

a

three

position

switch.

Rotary

Switch

Some

basses

are

equipped

with

a

rotary

switch

that

controls

the

electronics

and

has

four

positions.

1.

Standby

(full

clockwise

position)

-

All

controls

are

off.

2.

Active

with

presetable

Mid

Boost

-

The

bass

and

treble

controls

are

active.

There

is

also

a

presetable

boost

added

to

the

midrange

frequencies.

To

adjust

the

amount

of

midboost,

remove

the

backplate

and

adjust

the

miniature

potentiom-

eter

located

between

the

rotary

switch

and

the

tone

controls.

The

amount

of

midboost

can

be

adjusted

from

approximately

1db

to

8db.

Maximum

midboost

occurs

at

full

clockwise

rotation.

3.

Active,

Flat

-

The

bass

and

treble

controls

are

active

4.

Passive

-

The

lower

tone

control

knob

(bass)

acts

as

a

standard

control

knob.
