Things you will need
Screwdriver; cellophane tape; rubber bands; scissors; two AA
alkaline batteries or two zinc-carbon batteries. (* NiCd and other
rechargeable batteries have low voltage. Therefore the guitar
may not work when these batteries are used. Oxyride batteries
have high voltage. Using these batteries may break the circuit.)
Notes for tightening screws
When tightening screws, firmly press the screwdriver
straight against the screw and turn. It is said that 70
percent of the force applied is used for pushing against the
screw and 30 percent for turning it. The types of screws
used are those that carve grooves into the plastic as they
are inserted (self-threading). For this reason, the screw
hole may be damaged if you exert too much force when
tightening the screw. Since it is difficult to turn a precision

Q. Turning the tuning peg does not cause the pitch to rise.
A: The initial string tension may be insufficient. Remove the neck
cover, loosen washer head screw securing the string in question,
increase the tension in the string, and then retighten the screw.
A: Note that excessive tightening of the tuning peg can damage the
threads on the tuning shaft. If this has occurred, remove the string
in question, move the peg lug to a position beyond the damaged
threads, and then tighten the string.
Q. The guitar cannot be tuned properly.
A: Check whether the bridge has become detached or is angeled
incorrectly.

1 Insert the batteries and turn the
power on
Insert the batteries into the battery box and turn the
volume dial to ON. The LED power indicator lights when
the power is on. You can adjust the volume with the
volume dial.
After you have actually made some sound, try changing
the spacing between the strings or the position of the
pickup. You may find a difference in ease of play and in
the sound. Try moving them around until you find
positions that you like.
Loosen the screws securing the pickup
before adjusting the position of the pickup.

2 Let’s tune
If you have a musical instrument nearby, tune the guitar
using the scales of the instrument. Turn the pegs to adjust
the tension of the strings until getting the desired pitch.
When you turn the pegs, you are increasing the tension in
the strings from loose to tense. The pitch will gradually
increase while you are turning the pegs. Stop turning when
you have reached the desired pitch. If you have tuned too
high, turn the pegs to reduce the tension in the strings and
start tuning again. Because the tension in a string changes
during tuning, it may affect the other strings. Since the
tuning of one string will affect that of the others and may
change their pitch, once you have finished tuning all four
strings, start again from the thickest string.
Change a string if it has broken or become worn. Use strings for
electric gutars. We recommend the string gauges to the right. To
change the string, (1) turn the pegs so that there is no tension
remaining in any of the strings. (2) Remove the neck cover and body
cover. (3) Remove the washer head screw on the back of the neck
that is securing the string to be changed. (4) Remove the bolt
securing the string anchor shaft. (5) Pull and lift up the string anchor
shaft and remove the string from the shaft. (6) Pass the new string
through the shaft and retighten the string.

Useful Tips
How to hold the Mini
Electric Guitar
Holding the guitar securely is
a key point in playing a guitar.
Your left hand should gently
grip the neck while the right
hand holds the body.
Pose
The Mini Electric Guitar is very delicate. The angle of the neck
sensitively affects the sound. Turning the neck up in order to see the
fret (left picture) or peeking into the fret by slouching your back (right
picture) are not good posture. Even when you tune the guitar, keep
holding your body as the same way as when you play.
14
JR.SCIENTIST
Holding a pick, and play
Hold the pick with thumb and index finger.
Strum the string near the pickup. Use side of
your palm to mute the string.
Alternate picking is a technique that employs
strictly alternating downward and upward
picking strokes in a continuous run, and is
the most common method of plectrum
playing.
It is easier to play if your thumb is relaxed
and points toward the tip of the pick.
Adding expression to the sound
Let's learn some techniques that will make
you sound like an advanced player.
Vibrato
Hold a string in one position and shake the
string. The rapid shake of the string bends
the sound and makes vibrato. Shown in the
pictures below, the most common method is
to hold a string in one position and rapidly
twist the wrist and shake the finger back and
forth. You can use another method for the
Mini Electric Guitar to create a vibrato. Hold
a string in one position and change the
pressure (hard and soft) rapidly.
Tapping
One of the more advanced and impressive
techniques is tapping.
Tapping is performed either one-handedly or
two-handedly incorporating hammer-ons and
pull-offs. Hammer-on is done by sharply
bringing a finger down on the fingerboard to
make a sound. Pull-off is to make sound by
pulling off a fretting finger slightly across the
face of the string. It is a very effective
technique and makes a performance very
dramatic.
It is easier to tap if you hold the guitar neck up
right. It is not force that makes tapping loud,
but more the way you tap. Practice finger
movement patiently till you get a hang of it!
