PART 1 GA204 Acoustic Guitar

Care Of Your Instruments
• We recommend that you always keep your instrument
in a case or gig bag when transporting or storing it. This
reduces the possibility of damage due to nicks and
jams,or sudden changes i climate or atmosphere.
• Never put your instrument in the trunk of your car or
place anyting on top of it.
• Perspiration can damage the finish of your instruments
so always wipe down your guitar with a clean soft cloth
after playing or before storing.Polish with high gloss
guitar polish will prolong the life of the finish.

Tuning Your Instruments
We recommend standard guitar tuning to A-440,using
the electronic tuner.The following chart shows standard
tuning.The 1st string is the smallest diameter.Tune the
two outside string first,then tune towards the center.This
aqualizes the pressure on the bridge and allows rapid
tuning.

Action Adjustment
• Action is the distance that a string must be depressed
before it meets the fret.Action measurements are taken
in 64th's of an inch,and are calculated from the top of
the 12th fret to the underside of the string.We sets the
action on all instruments at the factory for optimum
playability.On occasion,lower than standard settings are
desired by the players.Lower than standard action often
result in “buzz” or “rattle”.This is caused by the string
vibrating against the fret.Buzz or rattle caused by lower
than standard action is not considered a defect of the
instrument.

Action Adjustment
Action at the 12th fret
Treble Side
Bass Side
5/64
7/64
For action at the first fret,all instruments are set at the same height.
Treble strings are cut to 1/64” and the action progresses up to 2/64”
on the bass strings. Be sure that the truss rod is properly adjusted
before setting action.

Truss Rod Adjustment
All guitar necks are subject to great stress as a result of
string tension.humidty or changes in
climate.Occasionally there are times when the neck may
need adjustment.The truss rod is adjustable at the
soundhole,using an allen wrench or an adjustment
wrench.
Note:This adjustment shoule be performed periodically
and only by qualified repair personnel.Over adjustment
can result in damage to the instrument and will not be
covered under warranty.

Restringing Your Instrument
As simple as it may sound,proper string installation is
critical to the playability to your instrument.An incorrectly
installed string can slip and cause the instrument to go
out of tune.
1.At the Bridge
The lower end of the instrument is strung as shown on
the page.

Restringing Your Instrument
2.At the Headstock
To fasten a string on the post and prevent slipping,bring
the string up the center of the instrument to the post
desired.Put string(A) through the hole or slot in the post
at (B) to (C);around the upper side of the post(D),and
under the string(A) at (B),back again around the string
post(D).Now when you wind the string it will lock itself
against the post.

EQ Control Knobs and Switches
EQ is a device that converts the
sound of the guitar into signals
and sends them to the amplifier.
To use EQ, a 9V battery
with sufficient power should be
put in. If EQ is not used for a
long time, the battery should
be taken out.
