System has been designed

with

your

needs

in

mind

.

Through extensive research,

Kustom

amplifiers

have been engineered

and

con-

structed

with

the

finest material

and

components available.

A wide

variety

of

highly

technical requirements

and

specifications,

which

each

piece

of

equipment

must

comply

with,

has been incorporated

to

give

your

Kustom

maximum

performance

and

dependability

.

On

the

TONE

CONTROL

OPERATION

CH

AN

NEL I - BASS

As

a general rule, the

amount

of

control

(boost

or

cut),

any one

of

the

tone

controls

has

will

be greatly

influenced

by

the

type

of

bass

guitar

and

pick

-

up

combinations used.

The

electric

bass

guitar has a funda-

mental frequency range

of

from

approximately

42Hz

(open

low

E)

to

approximately

200Hz (

12th

fret

of

4th

string).

The

dominant

harmonic overtones

occur

in

the

frequency range

from

about

160Hz

to

700Hz.

The

relationship between

the

fundamental and these harmonics determine

the

tonal

quality

of

the

amplified

sound.

Tone

controls

allow

the

musician

to

control

this relationship.

The

tone

controls

can

only

control

the frequencies

within

their

operating range. As

an

example,

if

the

musician

is

using

an

electric

bass

guitar

with

two

pickups, and

he

is

using

the top

pickup

(the

one closest

to

the

fret

board) and playing

with

his fingers, the

treble

control

will

exhibit

very

little

control

action.

This

is

due

to

the fundamental frequencies being

the

predominent

components. There are very

few

harmonic

overtones generated

when

a

bass

is

played in

this

manner, and therefore, there are very

few

harmonics

with-

in

the

control

range

of

the

treble

control.

On

the

other

hand,

if

the musician

is

playing using

the

bottom

pickup

and using a

pick,

the

treble

control

will

exhibit

a great deal

of

control

action.

This

is

due

to

a larger

quantity

of

harmonic overtones

in

relation

to

the fundamental frequency.

The

Bass

control

will

always

exhibit

a noticeable degree

of

boost and

cut

with

almost

any

type

of

playing style

or

pickup

configuration.

This

is due

to

the

simple fact

that

you

cannot have

harmonic

over-

tones

without

a fundamental and

the

bass

control

action

is

centered in

the

fundamental frequency range.

The

clarity

control

determines the level

of

the lowest fundamental frequencies produced

by

the

electric

bass

guitar

.

The

word

clarity

was chosen because

more

low

fundamental frequencies present

cause

a deeper

and sometimes

muddy

sound.

By

use

of

the

clarity

control

the

depth

of

sound can be adjusted

for

almost

any

type

of

music

or

playing environment.

This

control

is

especially useful in adjusting the

amplified

sound

for

different

sizes

and shapes

of

rooms

or

clubs.

AL

As

previously stated,

the

amount

of

cont

r

ol

(boost

or

cut),

any one

of

the

tone

controls

has

is

greatly

influenced

by

the

type

of

guitar, strings, playing style and

pickup

configurati

on.

Channel

11

is

designed

to

all

ow

a

bass

guitar

ist

a

modified

tone

control

ac

t

ion

and also

to

allow

fo

r proper equalization when using a

standard electric guitar. A

brief

explanation

of

this channel's action when using

an

electric guitar

follows:

The

electric guitar has a frequency range

of

from

approximately

74

Hz

(open

low

E)

to

1320

Hz (

12th

fret

high

El

.

The

dominant

harmonic

overtones

occur

in the frequency range

from

about

128Hz

to

5280Hz

.

The

relationship between

the

fundamental and these harmonics determine

the

tonal

quality

of

the

amplified

sound.

The

tone

control

circuitry

provides

the

musician

with

the means

to

control

the

relation-

ships between these frequencies.

The

tone

control

circuits

for

the

electric

guitar

are configured very much

like

those used

on

the

older

tube-

type

amplifier.

This

arrangement

has

the

advantages

of

unique

boost and

cut

points

and the disadvan-

tage t

hat

if

all

controls

are adjusted

to

minimum,

no

output

signal results.

The

tone

control

circuits

used

for

Channel 11are

of

the boost and

cut

type

and

like

those used

in

the

bass

channel,

can

only

control

the frequencies

within

their

operating range.

It

will

be

noticed, however,

that

when using

an

electric guitar,

control

action

will

be

more

apparent

under

most

operating

conditions

than

for

the electric

bass.

This

is

due to t

he

ability

of

the

guitar

to

play

chords. The str

umming

of

an electric

guitar

produces

an

extremely

complex

signal

which

in most instances

has

a fundamental and

at

least one

harmonic

overtone in one

of

the

tone

control

operating ranges.
