Controls the volume of the untreated instrument level at the ORGAN OUTPUT jack.

Controls the overall volume of the ORGAN preset.

MOD controls the speed of modulation. 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 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.


Press the BYPASS Footswitch to toggle the B9 between buffered Bypass
and Effect mode. The status LED lights when in Effect mode.???í???í

DRY outputs the signal present at the INPUT Jack through a buffer circuit.

ORGAN outputs the mix set by the DRY and ORGAN controls.

1. Fat & Full- This sound adds an extra octave below and above to
make your guitar sound twice as big. Fills out any band in an instant!
MOD Type: Chorus.

2. Jazz- This preset has the cool, smooth jazz tone reminiscent of the late great organist Jimmy Smith. MOD Type: Chorus.

3. Gospel- This preset has the upper octave drawbars added to capture that great soulful organ tone. MOD Type: Chorus.

4. Classic Rock- This preset captures the classic rock sound of songs
like Procol Harums Whiter Shade of Pale. Add a touch of distortion
for a classic dirty organ. MOD Type: Chorus.

5. Bottom End- This preset has the lower draw bar sound. Perfect for
adding bottom to your guitar or playing B3 bass sounds. With the CLICK
control up you can lay down a bass line like the one on Sugarloafs
Green Eyed Lady. MOD Type: Chorus.

6. Octaves- This preset uses the fundamental tone plus one octave above.
This sound is great for songs like Led Zeppelins Your Time is Going
to Come. MOD Type: Chorus. CLICK control adds not only key click, but
higher harmonics.

7. Cathedral- Turn up the reverb and you are at the seat of a giant
cathedral organ! Psychedelic rock tones easily pour out. MOD Type:
Tremolo. CLICK adjusts the tremolo depth.

8. Continental- This is the classic combo organ sound similar to classic
songs 96 Tears,Woolly Bully and House of the Rising Sun. MOD
Type: Vibrato. CLICK controls vibrato depth.

9. Bell Organ- If you crossed an electric piano with an organ this is
it. MOD Type: Tremolo. CLICK adjusts the amount of bell or chime added
to the sound.

1. The B9 is best as the first pedal in an effects chain. Place
modulation, delay and reverb effects after the B9. The unit will not
perform well if placed in the effects loop of a guitar amp.

2. The unit performs best using the bridge pickup of a guitar. If a
guitars pickup has a weak output, performance can be improved by
putting a clean boost or a compressor in front of the B9. It is not
advised to place a distortion or overdrive in front of the B9. This will
muddy up the input signal and cause the tracking to be unstable. If
overdrive or distortion is desired its best to place it after the B9.

3. Some guitar amplifiers have a uneven peaky frequency response that
may cause some sounds to be over accentuated. A compressor in front or
after the B9 can help smooth this out. This helps for a guitar player
whos playing is less than desirable in the dynamics department.

4. The B9 was designed to be used with a guitar. The unit can be used
with a bass guitar BUT the range the bass player can play will be
limited. The unit tracks best above the C note, third fret on the A
string. Below that performance is compromised.

5. The top range using a guitar in standard tuning is the 23rd fret. Above that the organ sound will not be heard.

6. The B9 tracks great and will follow whatever you play, but sloppy
guitar playing will sound like a sloppy organ player. The B9 will bend
notes just a regular guitar does. Organs do not bend, so for a more
authentic organ sound limit bending.
