Mode d’emploi
The G1D is a high-performance guitar synthesizer
pickup/driver designed for use with the Yamaha G50
Guitar MIDI Converter. When properly installed and
adjusted it can add high-performance MIDI guitar
synthesizer capability to just about any electric or
steel-string acoustic guitar.
Please read this owner’s manual carefully, and
follow the installation instructions within in order to
ensure proper operation.

Precautions !! PLEASE READ THIS BEFORE PROCEEDING !!
■ Location
Do not expose the G1D 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 G1D 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
12), 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, bumping,
or placing heavy objects on the instrument can
result in scratches and more serious damage.
• Be careful not to damage the G1D 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 alcohol or thinner.
■ Service and Modification
• The G1D 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.

1 Pickup
This is the actual “pickup” unit which converts
the physical motion of the guitar’s strings into an
electrical signal which can be processed by the
G1D and transmitted to the G50 Guitar MIDI
Converter.
■ CAUTION!
• Because of its slender dimensions the pickup
unit is quite delicate and can be damaged if subjected to unnecessary force, bending, or twisting.
Handle the pickup carefully!
2 Multi-pin Cable Connector
This is the main output from the G1D. One end
of the multi-pin cable supplied with the G50 Guitar
MIDI Converter is plugged in here, and the other
end of the cable is plugged into the DIVIDED
INPUT connector on the G50. The multi-pin cable
connector delivers both the individual string output
from the G1D pickup and the combined output
from the guitar’s output jack to the G50 Guitar
MIDI Converter. It also supplies power from the
G50 to the G1D, and sends the control signals
produced by the G1D UP/DOWN buttons and
VOL control to the G50.
5 Volume Control
Controls the volume of the MIDI tone
generator(s) connected to the G50 Guitar MIDI
Converter (the G50 translates the position of this
control to MIDI master volume data which is sent
to the tone generator). Use the guitar’s original
volume controls to adjust the volume of the direct
guitar sound.
6 UP/DOWN Buttons
These button can be used to select different
synthesizer voices and select other functions while
playing the G1D. Press either button briefly to
increment or decrement the G50 Guitar MIDI
Converter memory number by one (and thereby the
voice number of the synthesizer or tone generator
it is driving), or hold either button for continuous
scrolling in the corresponding direction.
7 GUITAR/MIX/SYNTH Selector
Selects the type of output to be delivered via
the multi-pin cable connector to the G50 Guitar
MIDI Converter, as listed below:
GUITAR Only the direct guitar sound will be
heard (i.e. no synthesizer sound will be
produced).
MIX Both the direct guitar sound and
individual-string synthesizer output
will be heard.
SYNTH Only the individual-string synthesizer
output is sent to the G50 (no direct
guitar sound will be heard).
3 Direct Guitar Input Jack
This jack receives the combined output from
the guitar’s normal pickups from the guitar’s output
jack. The short cable supplied with the G1D is
used to connect the guitar’s output jack (large 1/4"
phone jack end of the cable) to the G1D direct
guitar input jack (small mini-jack end of the cable).

Installation
Installing the G1D on a guitar is not a
difficult process, but it does require care and at
least a modicum of mechanical ability. If you
don’t feel totally confident that you can handle
the job, it might be a good idea to leave the
installation to someone experienced in guitar
modification or repair.
Guitar Compatibility
The G1D can be installed on most electric and
steel-string acoustic guitars, with the following
exceptions:
• Since the G1D employs a magnetic pickup, it
will not work with nylon or other non-metallic
strings.
• The G1D is designed for use with 6-string
guitars. It will not work properly with 12-string
guitars or other non-standard string configura-
tions.
• The G1D pickup should be installed between
the guitar’s bridge and bridge pickup. Installa-
tion may not be possible if there is not enough
room between the bridge and bridge pickup of
your guitar, or between the guitar top and
strings.
IMPORTANT!
Make sure your guitar’s neck (truss rod) and
string height/intonation (bridge) are properly
adjusted before installing the G1D.
Installing the Controller
Unit
Install the controller unit before installing the
pickup, being careful not to damage the pickup
during the installation process.
A number of installation options are provided:
• Screw.
• Double-sided adhesive tape.
• Re-usable adhesive pads.
• Velcro fastener.
• Bracket.
• Suction cups.

1. Determine the optimum
location for installation.
Normally, the controller should be attached
somewhere behind the guitar’s bridge, as shown in
the illustration. It should be accessible, but it
should not interfere with your playing or any of the
guitars controls or adjustments. Consider the
following points carefully when deciding on the
best location to install the controller:
Pickup
Direct guitar’s cable

• Velcro fastener.........................................1
• Bracket..................................................... 1
• Suction cups ............................................ 3
Multi-pin cable
• The controller and pickup cable should not get
in the way of your picking-hand at any time.
Make sure the location you choose will not
affect your playing style.
• The controller should not block or hamper
access to any of the guitar’s controls: tone,
volume, bridge adjustments (especially watch
out for intonation/saddle screws accessed from
the rear of the bridge).
• The controller must be well within reach of
both the pickup cable (when the pickup is in its
final installed position) and the direct guitar
cable
• Neither the controller unit itself nor any of the
connected cable plugs should extend beyond the
body of the guitar to prevent accidental damage.
