Electro-Harmonix B9 Quick Manual

Organ Machine
Congratulations on your purchase of the Electro-Harmonix B9. The B9 transforms the
tone of a guitar and/or keyboard into that of a convincing full body electric organ.
The 9 presets were finely tuned to emulate some of the most popular and classic
electric organ tones. The B9 provides control over percussive attack level, modulation
speed, organ and dry volume. The tracking on the B9 can keep up with the quickest
musical passages.
WARNING: Your B9 comes equipped with an Electro-Harmonix 9.6DC-200BI power supply
® ®
(same as used by Boss & Ibanez : 9.6 Volts DC 200mA). The B9 requires 100mA at 9VDC with
a center negative plug. Using the wrong adapter or a plug with the wrong polarity may damage
your B9 and void the warranty.
GETTING STARTED
Connect the supplied power adapter to the 9V power jack. Plug your instrument into
the INPUT jack; connect your amp to the ORGAN OUTPUT jack. Set the DRY knob to
minimum and all the other top row knobs to about mid position. Select the preset
named FAT & FULL and step on the footswitch to turn on the LED. Play your
instrument and adjust controls to your liking. MOD controls modulation speed and
CLICK controls percussive click level.
DRY VOLUME KNOB
Controls the volume of the untreated instrument level at the ORGAN OUTPUT jack.
ORGAN VOLUME KNOB
Controls the overall volume of the ORGAN preset.
MOD KNOB
MOD controls the speed of modulation. Modulation can be completely turned off
when MOD is set fully counterclockwise. The type of modulation is contingent on the
preset selected. The different types of modulation available are vibrato, tremolo and
chorus. See the preset descriptions for modulation type.
CLICK KNOB
CLICK controls percussive click level. It was designed to simulate the harmonic
percussion effect on classic B3 and C3 organs. The click will be added to the very first
note or chord played. The click will retrigger only when current notes have been
released and their amplitude falls below a threshold. For a few presets, CLICK
controls parameters unique to the preset. See the preset descriptions for details.

BYPASS FOOTSWITCH

signal is outputted regardless if the B9 is in Effect or Bypass mode.
ORGAN OUTPUT JACK
ORGAN outputs the mix set by the DRY and ORGAN controls.
