Electric Acoustic Guitar
Owner's Manual
Thank you for choosing a Yamaha electric-acoustic guitar.
In order to make the most of the advanced features and perfor-
mance provided by your guitar, please read this manual care-
fully before using the instrument.
PRECAUTIONS
l Before connecting the guitar to the amplifier, refer to the "Battery
Replacement" section and install the batteries.
l Always set the guitar's VOLUME control and the volume control
on the amplifier to their minimum levels when connecting or dis-
connecting the cable.
l The built-in preamplifier is automatically turned ON when a guitar
cable is connected to the output jack. When not using the instru-
ment, or when playing it without amplification, be sure to remove
the guitar cable from the output jack so that the preamplifier pow-
er is turned OFF. Also, if the instrument is not going to be used for
an extended period of time, or when battery power is depleted,
we recommend that the batteries be removed in order to avoid
power consumption or leakage.
