BASS PREACHER
Compressor/Sustainer
Congratulations on your purchase of the Electro-Harmonix Bass Preacher.
The Bass Preacher is a compact compressor/sustainer effect with variable
parameters allowing for extreme or subtle adjustments of the dynamic
qualities of your bass playing. Whether you want to transparently level out
the notes of your playing, or create a more extreme, squashed sounding
effect, the Bass Preacher can be dialed in to the perfect compression sound.
Although designed with bass guitar in mind, the Bass Preacher also works
great on guitar for those seeking a more subtle and transparent effect than
what other stompbox compressors offer.
The input sensitivity ranges from -10 dBu to +2 dBu, making it a perfect fit
for both passive and active basses of varying output levels. The Bass
Preacher has a maximum gain reduction of 21 dB, with enough make-up
gain to return your signal to full volume at maximum sustain (compression).
The Attack switch changes the response time to give you additional control
over the sound of the compressor. The Bass Preacher features true bypass
circuitry.
-USING HE BASS PREACHER-
Use the footswitch to turn on the effect. A red status LED illuminates to
indicate that the effect is engaged. Adjust the SUS AIN knob for the
desired amount of compression. Adjust the VOL knob to cut, match, or
boost the outgoing signal in relation to the incoming signal. Select AST,
MED, or SLOW with the A ACK toggle switch to change the timing of the
onset of compression. With ATTACK in FAS mode, the compression
engages immediately upon playing a note, producing a more squashed
sound. In SLOW mode the compression engages more slowly, allowing
more initial transients to come through. The MED mode is a compromise
between the two attack envelopes.

-CON ROLS & I/O Jacks -
Footswitch & Status LED – When the effect is engaged this red LED will
illuminate. When power is applied, the Status LED glows brightly to signal
that all operational voltages are satisfactory. The LED will not light if the
Bass Preacher is bypassed. Press the footswitch to toggle between effect on
and true bypass mode.
VOL Knob – Use VOL to adjust the amount of makeup gain.
SUS AIN Knob – Turn SUS AIN to set the amount of compression.
A ACK Switch – Toggle A ACK to set the timing of the attack/decay
curve.
INPU Jack – Plug your instrument or the output of another effects pedal
into this ¼” jack. The input impedance is 450kΩ.
AMP Jack – The AMP jack outputs the Bass Preacher’s audio signal. The
output impedance ranges from 150Ω to 2.8kΩ.
9V Power Jack – The Bass Preacher accepts 9V Batteries, and can also be
powered from an Electro-Harmonix 9.6DC-200 power supply. Plug the output
of the AC adapter into the 9V power jack located at the top of the Bass
Preacher. The Bass Preacher draws 33mA at 9VDC with a center negative
plug. The Bass Preacher accepts Boss
®
and Ibanez
®
style AC Adapters
capable of delivering at least 50 mA.
Warning: Do not use an incorrect power supply or you risk damaging the
Bass Preacher and voiding your warranty. Always check the specifications on
the power adapter you intend to use before plugging it into the Bass
Preacher.
- CHANGING HE BA ERY -
To change your 9V battery, remove the four screws on the bottom of the
Bass Preacher. Take off the bottom plate and change the battery. Do not
touch the circuit board while the bottom plate is off or you risk damaging a
component.
