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 THE BASS PREACHER-
Use the footswitch to turn on the effect. A red status LED illuminates to indicate that the effect is engaged. Adjust the SUSTAIN 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 FAST, MED, or SLOW with the ATTACK toggle switch to change the timing of the onset of compression. With ATTACK in FAST 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.
-CONTROLS & 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.
SUSTAIN Knob - Turn SUSTAIN to set the amount of compression.
ATTACK Switch – Toggle ATTACK to set the timing of the attack/decay curve.
INPUT 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 THE BATTERY –
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.
