Congratulations

on

your

purchase

of

the

BBE

Model

381

Guitar

Pre-amp!

This

two

channel

guitar

pre-amp

offers

flexibility

unequaled

in

today’s

market

place.

With

the

BBE

38Ts

two

channels,

the

player

is

able

to

achieve

the

more

traditional

clean

and

overdrive

tones

while

leaving

room

to

create

some

unique

tones

of

his/her

own.

An

important

advantage

with

the

BBE

381

Guitar

Pre-amp

is

that

all

of

the

controls

are

front

panel

mounted.

This

allows

for

an

instantaneous

status

report

of

all

controls,

at

a

glance.

Additionally,

the

BBE

381

Guitar

Pre-amp

is

equipped

with

both

Main

Outputs

and

Recording

Outputs

to

increase

its

interfacing

capabilities.

So

whether

in

the

studio

or

on

stage,

the

BBE

381

will

indulge

players

of

any

style

or

caliber.

The

BBE

381

Guitar

Pre-amp

is

also

equipped

with

the

following

features:

1.

Custom

BBE

circuit

for

increased

tonal

quality

and

intelligibility

with

a

built-in

noise

suppressor.

2.

Passive

three

band

tone

controls

for

the

clean

channel

and

active

four

band

tone

controls

for

the

distortion

channel.

3.

Recording

Outputs

allow

the

user

to

plug

directly

into

a

mixing

console

or

to

record

direct

to

tape

and

still

have

that

full,

rich,

cabinet

sound

that

the

player

enjoys

hearing.

The

importance

of

this

feature

is

most

evident

in

eliminating

the

need

to

transport

a

speaker

cabinet

or

the

use

of

microphones

for

sound

reinforcement.

4.

A

Stereo

Effects

Loop

to

interface

the

BBE

381

with

the

most

popular

BBE

PROCESS

15.

IN:

This

switch

engages

the

BBE

process.

When

depressed,

the

position,

the

“GREEN”

LED

will

illuminate.

When

in

the

“OUT’

position,

the

“GREEN”

16.

BBE

PROCESS:

This

control

introduces

the

BBE

process

which

has

specially

modified

for

the

BBE

381

Guitar

Pre-amp.

The

BBE

process

gives

the

user

a

more

detailed

perception

of

tonality,

added

“bite”

and

increased

clarity.

The

guitar’s

lower

tones

will

be

tightened

without

losing

their

thunderous

effect...

all

without

adding

or

creating

any

additional

noise

or

harmonic

distortion.

When

the

knob

is

in

its

minimum

position,

no

process

is

taking

effect

and

the

circuit

is

in

its

noise

suppression

mode.

Turning

the

knob

clockwise

will

introduce

the

BBE

process.

Adjust

the

knob

to

mix

the

desired

amount

of

process

for

your

own

needs.

The

BBE

process

also

has

its

own

in/out

switch

for

comparison

of

the

processed

to

unprocessed

signal

on

the

front

panel

of

the

BBE

381

pre-amp.

Experiment

with

the

process.

Use

the

BBE

as

an

extension

of

the

tone

controls.

Please

note

that

the

BBE

process

is

not

an

effect,

but

an

improvement.

A

good

place

to

start

with

the

BBE

process

is

to

set

the

knob

to

its12

o’clock

position

and

adjust

accordingly.

Note:

The

BBE

process

is

applied

before

the

effects

send.

GB\IERAL

OPERATION

In

order

to

reduce

the

risk

of

damage

to

any

equipment,

properly

connect

all

cables

and

power

cords

before

turning

on

any

components

in

the

system.

Most

important

of

all,

ALWAYS

TURN

ON

THE

POWER

AMPLIFIER

LAST

TO

AVOID

DAMAGING

THE

SPEAKERS.

Select

either

the

Clean

or

the

Distortion

channel

via

the

front

panel

switch

or

the

Footswitch.

Next,

adjust

the

tone

controls

to

achieve

the

desired

frequency

response.

The

tone

controls

are

specifically

tailored

for

their

respective

channels

with

passive

circuitry

for

the

Clean

channel

and

active

circuitry

for

the

Distortion

channel

to

insure

accurate,

no

bleed

through,

adjustment

from

one

tone

control

to

the

next.

Used

with

a

variety

of

guitars

and

pick-up

configurations,

the

BBE

381

Guitar

Pre-amp

is

able

to

achieve

almost

any

tone

desired.

The

BBE

process

is

a

unique

feature

that

only

BBE

Guitar

Pre-amps

possess.

The

BBE

process,

most

noted

for

its

ability

to

increase

the

clarity

and

the

tonal

quality

of

the

music

program,

is

achievable

without

adding

any

unwanted

noise

or

harmonic

distortion.

Use

this

feature

as

an

extension

of

the

tone

controls

and

as

a

means

of

improving

the

overall

tonality

of

the

guitar’s

signal.

Use

the

front

panel

switch

to

compare

the

processed

to

unprocessed

sound.

The

advantage

of

having

the

BBE

process

will

be

further

emphasized

when

used

in

conjunction

with

effects

processors.

The

Master

Volume

controls

are

separate

for

each

of

the

right

and

left

outputs.

This

will

allow

the

guitar

player

added

flexibility

when

playing

live.

If

the

guitar

player

is

utilizing

the

system

in

a

stereo

configuration,

it

is

possible

to

achieve

an

adequate

volume

mix

from

side

to

side.

Any

volume

differences,

whether

created

by

different

impedance

speaker

cabinets

or

by

an

effects

processor

can

be

accommodated

quickly

and

easily.

Note:

The

Master

Volumes

will

affect

the

Main

Outputs

and

Record

Outputs

simultaneously.

The

Record

Outputs

are

a

welcome

feature

for

any

guitar

player

who

is

constantly

mobile

or

where

space

and

volume

levels

are

prohibitive.

The

connection

of

the

BBE

381

Guitar

Pre-amp

directly

to

a

mixing

console

or

tape

recorder

while

maintaining

a

warm

guitar

cabinet

sound

is

now

possible.

Additionally,

the

inconvenience

of

“miking”

or

transporting

a

guitar

speaker

cabinet

is

eliminated.

The

Effects

Loop

on

the

BBE

381

Guitar

Pre-amp

will

accommodate

any

rack-mount

or

pedal

effects

processor.

The

effects

send

level

will

vary

depending

on

the

tone

and

volume

control

settings.

provide

elementary

control
