Owner’s Manual

PRECAUTIONS

l

 Always set the guitar’s VOLUME control and the volume control on the 

amplifier to their minimum levels when connecting or disconnecting 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 instrument, 

or  when  playing  it  without  amplification,  be  sure  to  remove  the  guitar 

cable from the output jack so that the preamplifier power 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 bat-

teries be removed in order to avoid power consumption or leakage. 

l

  Even when the guitar cable is disconnected from the output jack, 

pow-

er is turned ON when the TUNER switch is ON (

). Always turn the 

TUNER switch OFF (

) after using the tuner.

This Yamaha electric-acoustic guitar incorporates a new pickup and 

electronics  system  designed  to  capture  and  deliver  a  real  acoustic 

sound like that of an acoustic guitar recorded with a microphone. 

In order to make the most of the advanced features and performance 

provided by your guitar, please read this manual carefully before us-

ing the instrument.

USING THE TUNER

q

 Press the TUNER switch (

) to activate the tuner. (The 

 lamps 

light.)

w

 Tune the guitar string until the note name of the desired pitch appears in the 

display.

e

 The string is in tune when only the   lamp lights in the center of the 

display.

USING A.F.R. (Auto Feedback Reduction)

If you experience problem feedback while performing, follow the A.F.R. set-

ting instructions below to effectively control the feedback.

q

 When feedback occurs, press the A.F.R switch after all sound other than the 

feedback has muted.

*Thesystemmayhaveadifficulttimedetectingtheproblemfrequencyiftwoormore

soundsarepresentatthesametime.

w

 The system automatically detects the frequency causing the feedback and 

applies a –12dB notch filter. The number of notch filter bands currently ap-

plied is shown in the display.

*Thesystemcanapplyamaximumof5notchfilterbands.

*If the detected frequency is the same or very close to a frequency that is already

e

 Hold the A.F.R switch until “

” appears in the display to cancel all notch 

filters. Or, switch off the power (unplug cable from output jack) to cancel all 

notch filters.

q

VOL Control: Controls the volume.

*Alwayssetthevolumetoitsminimumlevelwhenconnectingordisconnectingthe

cable.

w

3-Band Equalizer: Adjusts the LOW, MID, and HIGH frequency levels.

e

TUNER Switch: Switches the tuner ON (

)/OFF (

).

r

Display: Displays tuner information and settings, and A. F. R. functions.

t

TYPE  Switch:  Selects  the  pickup’s  mic  simulation  type  (1:  large  dia-

phragm condenser mic/ 2: small diaphragm condenser mic/ 3: ribbon mic).

y

FOCUS/WIDE Switch: Selects the setting for the simulated mic.

FOCUS: This setting delivers a clear tone appropriate for use when play-

ing with a band.

WIDE: This setting delivers broad tone appropriate for solo use.

u

RESONANCE  Control:  Rotating  to  the  right  delivers  more  body  tone, 

rotating to the left produces less. The knob’s central detent position is the 

standard setting.

i

BLEND Control: Controls the mix level of signals received from the pick-

up and the simulated mic. Rotate fully to the left for 100% pickup signal 

and fully to the right for 100% simulated mic signal.

o

A.F.R Switch: When feedback occurs, this function automatically detects 

the problem frequency and applies a filter to eliminate the feedback.

Sound  Hole  Cover  (supplied):  Inserting  the  sound  hole  cover  into  the 

sound hole effectively reduces feedback.
