NS CR Omni Bass Instructions
Strap system
The large, thin washer should be
placed between the instrument and the
hub (failure to use the washer can
damage the surface of the instrument).
Insert the attachment screw into the
threaded insert on the back of the
instrument. Use a 4 mm hex wrench,
flat screwdriver, or coin to tighten the
screw. The hub should be held firmly
but still be able to rotate.
Adjusting Pivot Friction
Adjusting Long Arm Friction
To adjust the arm friction, tighten or
loosen the two hex screws in the hub.
The screw closest to the long arm
should generally be tightened more
than the other screw, to provide more
friction on the long arm. The hex
wrench can be stored in the hole in the
ends of the tubes, but care must be
taken to insure that the hex wrench is
not positioned where it will scratch the
instrument when the arms are moved.
Rotate the arms into position
for use, and attach
conventional guitar style strap
to the ends of the arms. Place
strap over the shoulder like a
guitar, and adjust the position
of arms and rotation of the hub
to the desired position for play.
The instrument should remain
in position.

CONTROLS
Knob 1 - Volume
Knob 2 –Balance: counterclockwise for magnetic pickup, clockwise for bridge
pickup, center for both.
Knob 3 - Balance: counterclockwise for optimal pizzicato (plucked, sustained)
sound, clockwise for optimal arco (bowed and percussive plucked) sound, center
for both.
Knob 4 - Treble: boost and cut.
Knob 5 - Bass: boost and cut. Note:
For bowing, it is best to use the bridge pickup only in arco mode.
STRINGS
NS Bass Cello strings by D’Addario. The NS Bass Cello also accommodates most long
scale bass guitar strings.
STRING HEIGHT
Adjust bridge height with Philips head screws under the bridge, accessible from the back
of the instrument.

INTONATION (Fretted Model Only)
To adjust intonation, first loosen set screws in the top of the bridge with a 1.5 mm hex
wrench as shown below. If the intonation becomes sharp at the 12th and 24th fret, push
the top of the bridge away from the headstock using finger pressure. If the intonation
becomes flat at the 12th and 24th fret, push the bridge toward the headstock. A small
amount of movement is all that is required. Re-tighten the set screw when the best
intonation is achieved.
PICKUP ADJUSTMENT
Magnetic pickups adjust by loosening set screws in the anchor adjacent to the round coil
caps (use 1.5mm hex key). Hold at desired height and re-tighten set screw.
BATTERIES
Always unplug the instrument when not in use to save the batteries. Change both 9 volt
batteries at the first sign of distortion. These are located behind the lower back plate
and can be accessed by loosening the small plastic knobs.
TRUSS ROD
The truss rod will reduce relief when tightened. Use 5mm hex wrench, with access near
nut. Clockwise rotation decreases relief.
