NOTE:
If noise is noticeable when the bass is not being played, and the effect is on, adjust the
NOISE GATE THRESHOLD by turning it to the minimum position and then turn it slowly
to the point where the noise becomes unnoticeable (while not playing). Play the bass to
check that the effects sound is released OK. If the release is too abrupt or unnatural
sounding, try turning the NOISE GATE THRESHOLD down a little.
MODIFY mode
In MODIFY mode, you can add a upper 5th or a lower 4th sourd to the one octave high
effect sound. Or you can mute the original bass sound completely. Also, you can set how
the MODIFY footswitch works. The MODIFY LED lights when the mode is on.
The SELECT switch selects the type of effect when the MODIFY mode is turned on:
NOTE:
Please do not turn the SOLO mode on within 10 seconds of turning the power on, as
there may be an audible click.

MIX output
This outputs a mix of the direct and effect signals. If you plug into the EFFECT
output, this outputs the direct signal only.
EFFECT output
This outputs only the effect signal.
Connect your bass to the INPUT jack.
Connect the MIX output to the input of your amplifier.
If you want to separate the bass and effects sounds, also connect the EFFECT
output to the input of a separate amplifier. In this case, MIX outputs the original
bass sound and EFFECT outputs the effect sound.
Turn your amp/s on.
Adjust the INPUT LEVEL while playing the bass. The level should be adjusted so
as the Red LED does not come on when playing at your loudest. However, since
the pitch cannot be determined properly if the level is too low, the level should be
adjusted as high as possible without turning on the Red LED.
Press the ON/OFF (left) footswitch to turn the effect on.
Adjust the TONE, DISTORTION and OUTPUT LEVEL to suit your taste.
ADD UPPER 5TH - Upper 5th is added to the effect sound.
SOLO - The direct signal is muted and only the effect sound is played.
ADD LOWER 4TH - Lower 4th is added to the effect sound.
For bass players who want to add more
depth to their sound, the UniBass is at your
feet giving great versatility and depth to
your playing style. It does this by shifting
the pitch one octave up and outputing the
original bass sound plus the effect sound
