OWNER’S MANUAL
Congratulations!
You are now the proud owner of the portable and powerful Crate BFX100 Bass
Amplifier with Digital Signal Processing. The BFX100 offers a wide selection of digi-
tal effects designed especially for the bass guitar, each of which are easily accessed
with a simple turn of a control knob. (No programmer’s degree required!) The BFX100
boasts an improved cabinet design with a front port, an extended range bass driver,
an extremely clean power amp and very flexible tone circuitry. The balanced line out
jack has a level control for the best signal match to a recording console or live PA sys-
tem, and is selectable for either pre or post EQ. The built-in limiter ensures pure,
clean power even at its full 100 watts output. An effects loop, a headphones jack, and
an extension speaker jack add to the overall versatility of this incredible bass amp.
Your BFX100 is Musician Made in the U.S.A., using only the best components.
Extensive testing at the hands (and ears) of skilled technicians and musicians
ensures you that this amplifier is the absolute best it can be.
In order to get the most out of your new bass amp, we urge you to read this man-
ual before you begin playing.
And thank you for choosing

10. DSP MODE: Select the type of digital
effect(s) applied to the signal with this con-
trol. The effects are described as follows:
13. INSERT: Connect an external effects
device using this jack. Use a stereo 1/4” male
Y-cord: ring = send, tip = return, sleeve =
ground. See the illustration to the right for
more information.
DELAY: Slapback delay effect
ECHO: Long delay effect with regeneration
CHORUS: Chorus effect
14. HEADPHONES: For private listening,
connect a pair of stereo headphones into this
jack. The internal speaker is disconnected
when headphones are plugged in.
FLANGE: Light flange effect
FUNK-WAH: Touch-sensitive wah-wah (“T-Wah”)
effect
15. SPEAKER: Use this jack to connect the
amplifier to an external speaker with a mini-
mum impedance rating of 4 ohms. The inter-
nal speaker is disconnected when this jack is
used.
OCTAVE: Adds secondary note one octave
lower than original note
CHO/HALL: Chorus effect with large hall reverb
effect
RM: Small room reverb effect
HALL: Large hall reverb effect
WARNING: TO AVOID POSSIBLE
HEARING DAMAGE, DO NOT
USE HEADPHONES IN THE
SPEAKER JACK!
11. DSP LEVEL: This is the output level con-
trol for the selected DSP effect(s). For a dry
signal (no effect), rotate the control full
counter-clockwise. Rotating the control
clockwise increases the magnitude of the
DSP effect(s) applied to the signal.
16. ON LED: This LED will illuminate when
the amplifier is turned on.
17. POWER: This switch applies AC power
to the amplifier. The amplifier is ON when the
side of the switch with the indicator (|) is
depressed.
12. DSP FOOTSWITCH: Connect a one but-
ton footswitch (such as the Crate CFP-1)
here for remote on/off control for the internal
DSP effects.

gain, contour and graphic EQ controls.
22. BALANCED LINE OUT LEVEL: Use this
control to adjust the output signal at the
Balanced Line Out jack (#20). This control
works independently from the the front panel
Master Level control.
19. AC LINE CORD: Plug this cord into a
properly wired, grounded, 120 volt, 60 cycle
outlet. DO NOT attempt to defeat the
ground connection of this power cord! If
your amplifier was purchased outside of the
United States, see the unit’s rear panel label-
ing for its power rating, and follow the above
guidelines.
Connecting to the Insert jack:
The Insert jack (#13) lets you patch external
effects into the amplifier just prior to its power
amp stage. Use Crate’s STP201, STP202 or
STP203 stereo-to-mono Y-cord or an adapter
such as Crate’s YPP117 and 2 1/4” mono signal
cables to connect to the effect as shown below.
20. BALANCED LINE OUT: This XLR-type
connector supplies a balanced preamp output
signal for connecting to a house mixing board,
recording console or external amplifier with
balanced inputs. The signal can be set to Pre
or Post EQ by the Pre/Post switch (#21). The
line out signal level can be controlled by the
Balanced Line Out Level control (#22).

21. PRE/POST SWITCH: You can select
either Pre or Post EQ for the signal at the
Balanced Line Out jack (#20) with this switch.
When the switch is depressed, the signal at
the jack is pre-EQ—a direct output, not affect-
ed by the gain, contour, or graphic EQ. When
the switch is in the out position, the signal is
