ELECTRIC ACOUSTIC GUITAR Owner’s Manual

SERVICE

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.

THE CONTROLS

BATTERY REPLACEMENT

Be sure to replace the battery as soon as possible when the battery check indicator lights in order to avoid reduced sound quality.

*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.

qPress the catch on the battery holder in the direction indicated by the arrow in the illustration q in order to unlock it.

wSlide out the battery case.

eRemove the old battery from the battery case, and insert the new battery making sure that the (+) and (–) terminals of the battery are positioned as shown in the illustration e. Use only a DC9V, S-006P (6F22) or equivalent battery.

rSlide the battery case back into the battery holder and press firmly so that the battery case locks into place.

qVOL.

Controls the instrument's volume. Volume is adjusted linearly from a level of 1 to 10 without any degra- dation in sound quality.

*Always set the VOL. level to "0" be- fore making any connections to the guitar's jack.

w BAT. (Battery Check) Indicator

When battery power is depleted the red LED will flash. In this condition, sound quality will not change how- ever; the battery should be replaced with a new one as soon as possible.

eEQUALIZER

LOW :

Adjusts the low frequency level (+/–12dB).

HIGH :

Adjusts the high frequency level (+/–12dB).

PRES. :

A d j u s t s t h e o v e r t o n e l e v e l (+/–12dB). Adjusts the brilliance.

rA.M.F. Control

tMID Control

Mid-range equalization is carried out by first selecting the center fre- quency with the A.M.F. (Adjustable Mid Frequency) knob. The MID knob can then be used to boost or cut (+/–12) the selected frequency.

CUT BOOST

By controlling the center frequency, more substance can be given to the tone.

For strumming, flat or cut settings are better, for lead or fingering boosting is recommended.

*The A.M.F. control will have no ef- fect when the MID knob is centered.

yBLEND

Blends the tone of the Bar Sensor (Piezo Pickup) and Condenser Mic. With the control centered, a 50:50 mix is achieved. Fully rotating the knob to the Piezo side allows only Piezo tone output. Fully rotating to the Mic. Side results in a mix of 70% Mic and 30% Piezo.

To obtain a natural sound, set the knob somewhere between its cen- ter and the mic side.

For strumming in a band, set the knob somewhere between its cen- ter and the Piezo side.

ADJUSTING SADDLE HEIGHT (only for CPX)

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 the screw).

•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.
