PLEASE KEEP THIS MANUAL
The G50 is a high-performance Guitar MIDI Converter designed to work in conjunction with the Yamaha G1D Divided
Pickup Unit installed on an electric or steel-string acoustic
guitar. The G50 offers unprecedented MIDI guitar synthesizer
performance with exceptionally fast response and a range of
advanced features that bring the true creative potential of MIDI
control to guitar players for the first time. A MIDI guitar system
incorporating the G50 and G1D is not only great for performance, but it gives guitar players an ideal means for entering
music data in a MIDI sequence recording system.
Please read this owner’s manual carefully, and follow the
instructions within in order to ensure proper operation. Also
keep this manual in a safe place for later reference.

Precautions !! PLEASE READ THIS BEFORE PROCEEDING !!
■ Location
Do not expose the G50 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.
■ USE THE CORRECT POWER SUPPLY
Power to the G50 should be supplied only from the
appropriate Yamaha AC adaptor (the PA-3B or another
adaptor specifically recommended by Yamaha). Use of
another adaptor may cause serious damage to the unit.
Also make sure that the adaptor you have is appropriate
for the AC mains supply voltage in the area where you
intend to use the G50. (The correct input voltage is
marked on the adaptor.)
■ Power Supply
• Turn the power switch OFF when the instrument is not
in use.
• The power adaptor should be unplugged from the AC
outlet if the G50 is not to be used for an extended
period of time.
• Unplug the G50 during electric storms.
• Avoid plugging the G50 into the same AC outlet as
appliances with high power consumption, such as
electric heaters or ovens. Also avoid using multi-plug
adaptors since these can result in reduced sound
quality and possibly damage.
■ Turn Power OFF When Making Connections
• To avoid damage to the G50 and other devices to
which it is connected (a sound system, for example),
turn the power switches of all related devices OFF
prior to connecting or disconnecting audio and MIDI
cables.
■ Handling and Transport
• Never apply excessive force to the controls, connectors or other parts of the instrument.
• Always unplug cables by gripping the plug firmly, not
by pulling on the cable.
• Disconnect all cables before moving the instrument.
• Physical shocks caused by dropping, bumping, or
placing heavy objects on the instrument can result in
scratches and more serious damage.
■ Cleaning
• Clean the cabinet and panel 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.
• Avoid placing vinyl objects on top of the instrument
(vinyl can stick to and discolor the surface).
■ Electrical Interference
• This instrument contains digital circuitry and may
cause interference if placed too close to radio or
television receivers. If this occurs, move the instrument further away from the affected equipment.
■ Data Backup
• The G50 contains a special long-life battery that
retains the contents of its internal memory even when
the power is turned OFF. The backup battery should
last for several years. When the backup battery needs
to be replaced “BALo” will appear on the display
when the power is turned on. When this happens, have
the backup battery replaced by qualified Yamaha
service personnel. DO NOT ATTEMPT TO REPLACE
THE BACKUP BATTERY YOURSELF!
■ Service and Modification
• The G50 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.
■ MIDI Connections
• When connecting the G50 to MIDI equipment, be sure
to use high-quality cables made especially for MIDI
data transmission.
• Avoid MIDI cables longer than about 15 meters.
Longer cables can pick up electrical noise that can
causes data errors.
YAMAHA is not responsible for damage caused by improper handling or operation.

G50 Overview
The G50 is basically an “interface” which converts the
analog output from a G1D Divided Pickup Unit installed
on your guitar (or directly from the guitar’s normal output
if used without the G1D in the mono synthesizer mode) to
corresponding MIDI data which is transmitted to a MIDI
tone generator to produce the “synthesized” sound output.
When you play a note or chord on your guitar, the G50
instantly generates MIDI data corresponding to the note(s)
you play — along with the appropriate pitch bend data if

you bend a note — so that you can use most standard
guitar techniques to play any voice that can be produced
by the connected MIDI tone generator — brass, strings,
organ, percussion … anything! You can play just the
synthesized sound, mix the synthesized sound with the
normal guitar sound played through a standard guitar
amplifier or sound system, or just play the normal guitar
sound.

The G50 has 128 “programs” that you can select and play.
In fact, you can edit each of these programs to provide
precisely the response and playing features you want. You
can, for example, specify the G50’s sensitivity in response
to notes you play on the guitar, the pitch bend range,
which voice on your tone generator will be selected when
the G50 program is selected, and much more. There are
also special “split” functions which let you play different
voices on different strings, or different voices at different
picking positions. You could, for example, play upright
bass on the lowest two strings (5 and 6) while playing
organ on the top 4 strings (1 through 4). The G50 offers
many other features that provide an extraordinary range of
creative possibilities.
