Congratulations
Thank you for purchasing the Yamaha B1D Divided Pickup Unit.
The B1D Divided Pickup Unit can pick up the vibrations produced by
an electric bass guitar’s strings, and transmit those signals to a Yamaha
Guitar MIDI Converter (G50). When properly installed and adjusted it
can convert almost any steel stringed bass guitar into a controller for a
guitar synthesizer system. It can be used on normal 4-string basses as
well as 5-string, and 6-string basses.
To get the most out of your B1D, please read this owner’s manual
carefully, and follow the installation instructions within, in order to ensure proper operation. Also, keep this manual in a safe place for future
reference.
■ Features
As well as any normal 4-string electric bass, the
unit can also be used on 5-string, and 6-string
basses. A number of installation options are
provided to allow for different guitar shapes, use,
and playing styles. Choose a method that best
suits your bass and playing requirements.
Methods for Attaching the Divided Pickup:
Special Fittings (removable), double-sided
adhesive tape, screw.
Methods for Attaching the Controller:
Velcro fastener, bracket, double-sided
adhesive tape, screw.
• One touch operation allows you to switch
between bass synthesizer sound and bass
guitar sound. Also, the synthesizer’s voice
and bass guitar’s signal can be output
separately or together, offering a wide
variety of sounds for added playing enjoy-
ment.
• Of course, the bass synthesizer’s volume can
be controlled. But you can also control other
functions like octave, parameter values,
program changes (that are transmitted from
the G50’s memory), and G50’s memory
numbers (which can be changed by a value
of +1/-1).

Precautions !! PLEASE READ THIS BEFORE PROCEEDING !!␣
■ Location
Do not expose the B1D to the following conditions to avoid deformation, discoloration, or more
serious damage.
• Direct sunlight (e.g. near a window).
• High temperatures (e.g. near a heat source,
outside, or in a car during the daytime).
• Excessive humidity.
• Excessive dust.
• Strong vibration.
■ Connections
• When connecting the B1D to the Yamaha G50
Guitar MIDI Converter, be sure to use the
specified multi-pin cable (supplied with the
G50 Guitar MIDI Converter).
• Always connect the direct guitar cable (page
4), even if you don’t intend to use the direct
guitar sound. The direct guitar cable is
essential for proper grounding, to minimize
noise and prevent electric shock.
• Always unplug cables by gripping the plug
firmly, not by pulling on the cable.
• Disconnect all cables before moving the
instrument or any connected equipment.
■ Handling and Transport
• Never apply excessive force to the controls,
connectors or other parts of the instrument.
• Physical shocks caused by dropping, bump-
ing, or placing heavy objects on the instru-
ment can result in scratches and more serious
damage.
• Be careful not to damage the B1D controller
when placing the guitar in a case or on a
stand.
■ Cleaning
• Clean the unit with a dry soft cloth.
• A slightly damp cloth may be used to remove
stubborn grime and dirt.
• Never use cleaners such as thinner.
■ Notes on Adhesive Tape
• Depending on the surface of the bass guitar the
finish may peel off or be altered chemically
when the pickup/controller is mounted using
adhesive tape (double-sided). To make sure, it
is recommended that you first try this method
of attachment by applying some tape at a place
on the guitar body which is not visible normally.
• If the pickup must be removed from the base guitar,
always use a fresh layer of double-sided adhesive
tape and/or cushion when reinstalling, as the
adhesive properties of used tape/cushion are reduced
drastically when peeled off the mating surface. Also,
before attaching the adhesive tape or pickup, clean
the mating surface thoroughly, as dust and grease
may cause the pickup to come loose.
■ Service and Modification
• The B1D contains no user serviceable parts.
Opening it or tampering with it in any way can
lead to irreparable damage and possibly electric
shock. Refer all servicing to qualified
YAMAHA personnel.
Yamaha is not responsible for damage caused by improper installation, handling, or operation.

13-pin cable connector to the Guitar MIDI Converter.
BASS: Only the direct bass sound (output from
the electric bass pickup) will be heard.
SYNTH: Only the synthesizer sound (output from
the divided pickup) will be heard.
MIX: Both the direct bass guitar signal and the
synthesizer sounds will be heard.
r Direct Bass Guitar Input Jack
This jack allows the B1D to receive the combined
output from the bass guitar’s normal pickups (bass
guitar signal) from the guitar’s output jack. Use the
supplied direct bass guitar signal cable when
making connections.
The bass guitar signal is output from the GUITAR
DIRECT OUT jack of the G50 (→ pg. 13).
