• Set all controls to their middle
position and set switches to their
off position (all LEDs unlit).
• Run a cable from your bass to
the Input jack of the Bass D.I.+
and run another cable from the
Bass D.I.+ Output jack to
your amplier.
• To use the D.I. (Direct Input)
function, run a balanced line
(microphone cable) from the Bass
D.I.+ Direct Output to your mixing
board or PA input.
• Turn on the Bass D.I.+ Clean
channel effect by depressing the
Effect footswitch (Effect LED lit).

designed to color your bass
tone with added punch,
denition and clarity.

set the distortion channel’s
output level.
• Push in the Gate switch to
activate the adjustable noise gate
with Smart Gate™ technology.
Set the Trigger knob threshold
low (counter-clockwise) to kill
hum and hiss from the distortion
signal while sustaining desired
signals without premature,
audible cutoff. To create a
dynamic distortion effect, set
the Trigger to higher (clockwise)
Trigger threshold settings so that
the gate only opens during loud
passages. The Gate’s yellow
status LED turns off when the
gate is opened and on when the
gate is closed.
• Use the Bass, Mid and Treble
controls to shape Clean and
Distortion effect tones.
• The Parallel Output can be used
to connect to a tuner or any
other parallel processing device.
• The Bass D.I.+ can be phantom-
powered through its Direct Output
jack from a phantom power-
capable mixing console. Push the
Phantom/Ground switch to its
down position to enable phantom
power or up position to ground lift
the Direct Output connection and
