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

performance 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 VOLUME control to "0" when plugging in or

unplugging the connection cable.

The battery check indicator (BATT.) will light briefly when a plug is

inserted or removed from the output jack. This is normal and does not

indicate a malfunction.

Be sure to remove the battery if the instrument will not be used for an

extended period of time in order to prevent possible damage due to

battery leakage.
