Introduction

Congratulations on purchasing the Fender®TBP-1
Tube Bass Preamp. This product is designed to
deliver creamy tube tone that is thick, natural and
balanced for both live and studio applications. By
combining a Fender®passive tone stack with modern
features like our Vari-Q™ semi-parametric EQ circuit,
Room Balance for your stage cabinets, and an
independent Tube Overdrive section, you now have
the best of the old and the new in a single rack space

with a 4-button footswitch to control it all.

What makes the TBP-1 special?

The passive tone circuit in the TBP-1 is the same one
used in such classic Fender®amps as the Twin
Reverb®and Dual Showman®. This “cut-only” passive
circuit means that the EQ controls are close to being
“flat” when set Bass: 2, Mid: 10, Treble: 2. Although
you are able to make tonal changes, you may notice it
doesn’t react the same as a typical solid-state front
end. The passive circuit feels integrated, with the
Volume and EQ controls affecting each other. A solid­state amp has a pre-defined shape with an active EQ
(typically allowing cut or boost as much as 15dB). This
difference takes a little while for some bass players to
get used to, but the tonal character of the passive
circuit feels right immediately!

Bi-Amped Bass Rig (Separate power amps and
speaker cabinets dedicated to lows and highs
independently)

1. Use guitar (shielded) cables to connect the high
frequency output and the low frequency output to
a stereo power amp (or two mono power amps).
Use speaker (unshielded) cables to connect each
side of the power amp (or from each individual
power amp) to the appropriate speaker cabinets

2. Use the Active Crossover to select the frequency
cross-over point

3. Any frequencies higher than the selected cross­over point will be sent to speakers assigned to the
higher frequencies

4. Any frequencies lower than the selected cross­over point will be sent to speakers assigned to the
lower frequencies

5. This is what is called a Bi-amped rig (bi- meaning
“two”). The advantage of this setup is its ability to
be more efficient with the signal and the player’s
ability to hear specific ranges of sound coming
through specific speakers (example: sending high
frequencies to a cabinet with 10’s and low
frequencies to a cabinet with a 15)

6. The result is less unwanted distortion as high
frequencies do not have to compete for headroom
with low frequencies

Normal Full-Range Rig

1. Connect the TBP-1 Main Output to the input of a
power amp

2. Run speaker cables from the power amp to the
cabinet(s) and GO!

Replacing the Pre-Amp Tone of an Existing Rig

1. Connect the TBP-1 Main Output to the Effects
Loop Return of a combo or head

2. The power section of the combo or head is now
powering the TBP-1

3. The pre-amp of the combo or head is not part of
the sound

4. This is a simple way to add the tone of the TBP-1
to an existing bass rig

Studio Recording Pre-Amp

1. Run a BALANCED LINE OUT (microphone) cable
from the back of the TBP-1 to a recording device

2. Choose POST on the BALANCED LINE OUT so
the EQ changes are included in the output signal

3. Jensen®line out transformer keeps signal clean
and strong

Front Panel Features:

• Fender®passive tone stack (remember passive
means CUT ONLY)

•• Delivers that creamy tube tone

•• Volume, Bass, Mid & Treble controls for the

“clean” sound

•• Pull Deep and Bright boost switches

•• A (roughly) flat tone would be with the EQ set

Bass: 2, Mid: 10, Treble: 2, with no Deep or
Bright boosts active

• Tube Overdrive section

•• Gain, Volume and Blend

•• This channel sits on top of the clean (which

preserves the warm clean pillow under the
overdrive)

•• Blend adjusts the clean vs. dirty ratio of the

tone (can be set “touch-sensitive”)

•• Footswitchable (4-button footswitch is

included)

• Vari-Q™ section – A smart semi-parametric EQ

•• Cutting frequencies automatically DECREASES

the width of the Q for a narrow, defined cut
(notch)

the width of the Q for a broader, more musical
boost

•• This intelligent Q control keeps “on the fly”

operation simple and effective

•• Footswitchable (4-button footswitch is

included)

• Room Balance – Global EQ shift for cabinet/stage
response

•• Clockwise cuts lower frequencies while

simultaneously boosting upper frequencies

•• Counter-clockwise boosts lower frequencies

while simultaneously cutting upper frequencies

•• Room Balance Does NOT affect BALANCED

LINE OUT output (soundman gets unaltered
signal)

• Master Volume – One level control that affects

everything (except Balanced Line Out, Tuner and
FX Send)

• Mute

•• Cuts all signal except for the Tuner and FX

Send

•• Footswitchable (4-button footswitch is

A. INPUT - Plug your bass in here. NOTE: This jack

overrides the rear panel Input jack {EE}.

B. –6 dB PAD - Reduces the Input sensitivity to allow

cleaner response with high-output bass guitars.

C. VOLUME - Adjusts the loudness of the Vintage

Tube Tone.

D. BASS / MID / TREBLE - Classic, cut only tone

stack. Pull the Bass knob out for a boost in the low­frequency range. Pull the Treble knob out for a
boost in the high-frequency range. Bright boost is
more apparent at mid settings of the Volume
control {C}.

E. ENABLE - Switches the Tube Overdrive section

on/off as indicated by the LED. Keep button out for
proper operation of the included footswitch.

F. GAIN - Adjusts the Tube Overdrive distortion level.

G. VOLUME - Adjusts the loudness of the Tube

Overdrive sound along with the Gain control {F}.

H. BLEND - Adjusts the mix of clean vintage tube tone

with overdriven tube tone when the Tube Overdrive
is enabled.

I. ENABLE - Switches the Vari-Q™ semi-parametric

EQ section on/off as indicated by the LED. Keep
button out for proper operation of the included
footswitch.

J. FREQ - Selects the center of frequency range that

the Level control {K} adjusts. NOTE: This knob has
no effect when Level is at “0.”

K. LEVEL - Adjusts the amount of boost or cut

(±15dB) at the frequency selected by the Freq
control {J}. Also adjusts the width or “Q” of the
frequency response as appropriate. In the boost
mode, the “Q” is automatically set wider, which is
more generally perceived as musically pleasing. In
the cut mode, the “Q” is narrow, useful to eliminate
a problem frequency, hum or resonance.

L. ROOM BALANCE - Room Balance is for the player

to “dial in the room” as a final touch of EQ. This
feature is OFF when in the center position (start the
EQ process with this control centered; dial it in
last). Turning the control clockwise emphasizes
highs, while de-emphasizing lows (great if the stage
sound is dark and muddy). Turning the control
counter-clockwise creates the opposite effect;
emphasizing lows while de-emphasizing highs
(helps with bright hardwood floors). This frees up
the EQ of the TBP-1 to design your TONE instead
of compensating for poor room acoustics.

M. MASTER VOLUME- Adjusts the overall loudness

of the TBP-1 in conjunction with the Gain and
Volume controls of active sections.

N. MUTE - Disables all TBP-1 outputs (except for the

Tuner and FX Loop Send jacks) as indicated by the
blinking LED. Keep button out for proper operation
of the included footswitch.

O. POWER - Switches the TBP-1 on/off as indicated

by the LED.

P. IEC POWER SOCKET - Connect the included

power cord to a grounded AC receptacle in
compliance with the voltage and frequency ratings
specified on the rear panel of your TBP-1.

Q. FOOTSW - Connect the included footswitch to

enable remote on/off switching of Tube Overdrive,
FX Loop, Vari-Q™ and Mute. NOTE: For proper
operation, front panel switches {E}, {I} and {N} must
each be left in the out, non-enabled position.

R. LF OUT - Low frequency output for bi-amping.

S. BALANCE - Adjusts the balance between the

LF Out and HF Out when bi-amping.

T. HF OUT - High frequency output for bi-amping.

U. FREQUENCY - Adjusts the crossover frequency

when bi-amping.

V. MAIN OUTPUT - Full-range output for connecting

to a power amp input or to a bass amp Return jack.

W. GND / LIFT - The Ground Lift switch should

normally be in the Ground (out) position. In the Lift
(in) position, the ground connection (pin-1) of the
Balanced Line Out jack {X} is disconnected from
the chassis, which may reduce hum noise in some
situations.

X. BALANCED LINE OUT - This jack allows you to

send a Jensen™ transformer isolated, hum-free
signal from the TBP-1 to external equipment (such
as a house mixing console or a recording device).

Y. LEVEL - Adjusts the output level of the Balanced

Line Output jack {X}.

Z. PRE / POST - Use this control to select if you

would prefer the bass signal from the Balanced
Line Output {X} to be affected by the EQ changes
you make (post) or before the EQ, to give an
unaffected signal (pre).

AA. TRIM - Adjust to compensate for external effects

devices volume difference when FX Loop is
selected with included footswitch. Full clockwise
rotation provides a +6dB boost, while full counter­clockwise provides a -6dB cut. Also useful for a
footswitchable solo boost (clockwise rotation)
when not using external effects.

BB. –10dBV / +4dBu - FX Loop level. Sets nominal

operating level for external effects. Use +4dBu for
professional rack-style effects. Use -10dBV for
battery operated pedal effects.

CC. RETURN / SEND - FX Loop jacks for external

effects. Connect Send to the input of your effects
device and Return to the output of your effects
device.

DD. TUNER - Connection for your bass tuner. Use the

Mute switch {N} while tuning, if desired.

EE. INPUT - Alternate connection for bass guitar

signal. Useful in some rack configurations. NOTE:
Front panel Input jack overrides this jack.

NOTE: Jacks {R}, {T}, {V}, {CC} and {DD} are balanced TRS (Tip/Ring/Sleeve) types, with
tip=positive (+), ring=negative (–) and sleeve=ground (GND). While standard sheilded TS
(Tip/Sleeve) “mono” guitar cables may certainly be used, the use of “stereo” TRS cables,
when available, may improve signal-to-noise ratio and/or reduce hum.

Introducción

Felicidades y gracias por su compra del Fender

®

TBP-1 Tube Bass Preamp. Este aparato ha sido
diseñado para producir un cremoso sonido a válvulas
compacto, natural y balanceado tanto para directo
como para aplicaciones de estudio. Con la
combinación de un tono pasivo de amplificador de
tipo torre Fender®con funciones modernas como
nuestro circuito EQ semiparamétrico Vari-Q™, el
Room Balance para sus recintos acústicos de
escenario y una sección de Saturación a válvulas
independiente, ahora tiene lo mejor del pasado y del
presente en una única unidad rack de un espacio con

una pedalera de 4 botones que controla todo.

¿Qué convierte al TBP-1 en algo especial?

El circuito pasivo de tono del TBP-1 es el mismo que
se utilizaba en los amplificadores Fender®clásicos
como el Twin Reverb®y el Dual Showman®. Este
circuito pasivo “solo de corte” implica que los
controles de EQ están cerca del “planos” cuando los
coloque en Bass: 2, Mid: 10, Treble: 2. Aunque puede
realizar cambios tonales, observará que no reacciona
igual que en las típicas unidades de estado sólido. El
circuito pasivo es muy integral, afectándose los
controles de EQ y volumen entre sí. Un amplificador
de estado sólido tiene un formato predefinido con un
EQ activo (que le permite realzar y cortar
habitualmente hasta 15 dB). Algunos bajistas les
cuesta habituarse a estas diferencias, mientras que el
carácter tonal del circuito pasivo les resultará útil y
directo de inmediato!

Montaje de bajo biamplificado (Distintas etapas de
potencia y recintos acústicos que se usan para los
graves y agudos de forma independiente)

1. Use cables de guitarra (blindados) para conectar la
salida de altas frecuencias y la de bajas
frecuencias a una etapa de potencia stereo (o dos
etapas mono). Use cables de altavoz (sin blindaje)
para conectar cada lado de la etapa de potencia (o
de cada etapa individual) a los recintos acústicos
correspondientes.

2. Use el crossover activo para elegir el punto de
separación de cada frecuencia

3. Cualquier frecuencia que esté por encima del
punto de crossover elegido será enviada a los
altavoces asignados a las frecuencias agudas

4. Por contra, cualquier frecuencia que esté por
debajo de ese punto será enviado a los altavoces
asignados a los graves

5. Por esto se llama montaje biamplificado (bi- de
“dos”). La ventaja de esta instalación es su
capacidad para ser más eficaz con la señal y la
posibilidad del músico de oir rangos concretos de
su sonido de altavoces específicos (por ejemplo:
puede enviar los agudos a un recinto con un
altavoz de 10” y los graves a uno de 15”)

6. El resultado es una menor distorsión no deseada
dado que los agudos no tienen que competir con
los graves por el margen o headroom

1. Conecte la salida principal del TBP-1 a la entrada
de una etapa de potencia

2. ¡Conecte unos cables de altavoz desde la etapa

del TBP-1 a un montaje de bajo ya existente
