ELECTRIC ACOUSTIC GUITAR
Thank you for purchasing the YAMAHA Electric Acoustic Guitar.
Incorporating a piezo pickup matched with a condenser micro-
phone, this instrument achieves a realistically natural sound never
before attained. A newly developed pre-amp section is utilized,
designed to maximize the microphone's characteristics.
The guitar's control section is simple, easy to use, and designed
to fit any playing style.
In order to make the most of the advanced features and perfor-
mance provided by your guitar, please read this manual carefully
before using the instrument.
PRECAUTIONS
The output jack is an EIAJ-standard 1/4" phone jack. Be sure
to use an appropriate connection cable.
The built-in preamplifier is automatically turned on when a
plug is inserted into the output jack. When not using the
instrument, or when playing it without amplification, be sure to
remove the plug from the output jack so that the preamplifier
power is turned off.
Always set the VOL. control to "0" when plugging in or
unplugging the connection cable.
The battery check indicator (BAT.) will light briefly when a
plug is inserted or removed from the output jack. This is
normal and does not indicate a malfunction.

Using the Sound Hole Cover
Feedback often occurs when controls are boosted on the electric
acoustic guitar to match the volume of other instruments when
playing in a band.
Another source of feedback results from using the BLEND control
to increase the output from the internal condenser mic.
When the instrument is used under the conditions described above,
the Sound Hole Cover should be inserted into the sound hole.
With the Sound Hole Cover in place, feedback is effectively re-
duced.

ADJUSTING SADDLE HEIGHT
String height can be adjusted at the bridge with the two adjuster
screws located on either side of the bridge. With the strings
loosened, rotate the adjuster screws to adjust string height. A
half turn will result in approximately a 0.4 mm adjustment.
• To raise the height of the strings → rotate the screw counter-clockwise (loosen
t
the screw).
CUT
BOOST
• To lower the height of the strings → rotate the screw clockwise (tighten the
screw).
After adjustment of the string height is complete, tune the guitar.
* When you lower string height, loosen the truss rod a little (convex or
back-bowed). When you raise string height, tighten the adjusting
rod a little (concave or up-bowed), fret buzz will stop.
