Name Explanation

1 DC IN jack

Accepts connection of an AC Adaptor (PSA series; sold separately). By using an AC Adaptor, you can play without being concerned about how much battery power you have left. * We recommend that you keep batteries installed in the unit even though youll be

powering it with the AC adaptor. That way, youll be able to continue a performance even if the cord of the AC adaptor gets accidently disconnected from the unit.

* Use only the specified AC adaptor (PSA-series). * If the AC adaptor is connected while power is on, the power supply is drawn from the

AC adaptor.

2 CHECK indicator

This indicator shows whether an effect is ON/OFF, and doubles as the Battery Check indicator. The indicator lights when an effect is ON. * If this indicator goes dim or no longer lights while an effect is ON, the battery is near

exhaustion and should be replaced immediately. &Changing the Battery

3 LINE OUT jack

This output jack is used for connecting to mixers, recorders, and other devices that accept line-level input. When a cable is also connected to the G.AMP OUT jack, the effect sound is output from the LINE OUT jack when the effect is switched on, while the output is muted when the effect is switched off.

&Connections

Before using this unit, carefully read the sections entitled: USING THE UNIT SAFELY and IMPORTANT NOTES (supplied on a separate sheet). After reading, keep the document(s) where it will be available for immediate reference.

Name Explanation

4 G.AMP OUT jack

This output jack is used for connecting to guitar amps and other effects processors. The effect sound or direct sound is output from here depending on whether the effect is switched on or off. When a cable is simultaneously connected to the LINE OUT jack, the output from the G.AMP OUT jack is muted when the effect is switched on, while the direct sound is output when the effect is switched off.

&Connections

5 INPUT jack

This jack accepts input signals (coming from an electric guitar, some other musical instrument, or another effects unit). * The INPUT jack doubles as power switch. Power to the unit is turned on when you plug

into the INPUT jack; the power is turned off when the cable is unplugged. When not using the effects unit, be sure to disconnect the plug from the INPUT jack.

6 Pedal switch This switch turns the effects on/off.

7 Thumbscrew When this screw is loosened, the pedal will open, allowing you to change the battery.

&Changing the Battery

8 [REVERB] knob Adjusts the amount of reverb applied to the sound.

9 [LEVEL] knob Adjusts the volume of the effect sound.

10 [BODY] knob Adjusts the resonance of the sound produced by the guitar body, altering the characteristic mellowness and breadth of the acoustic guitar sound.

11 [TOP] knob Adjusts the sense of attack and the harmonic content of the upper range. * If the sound is distorted, adjust by turning the [TOP] knob to the left (counterclockwise). * Distortion can also be suppressed by turning the [LEVEL] knob to the left.

12 [MODE] knob

Provides for selection of the tone. The knob can be used to select any of four tones.

STANDARD This tone is that of the popular Dreadnought acoustic guitar body style.

JUMBO This setting provides a tone characteristic of an oversized guitar body, a tone featuring a rich bass response along with a beautiful high end.

ENHANCE Providing a sharper attack than the standard tone, this tone does not become masked by the sounds of other instruments, even in bands and ensembles.

PIEZO This setting provides the tone of a round-back acoustic guitar, with subdued body resonance and a unique attack.

Precautions When Connecting 5 To prevent malfunction and equipment failure, always turn down the volume,

and turn off all the units before making any connections.

5 Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices.

When powering up: Turn on the power to your guitar amp last.

When powering down: Turn off the power to your guitar amp first.

5 Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.

Changing the Battery 1. Hold down the pedal and loosen the

thumbscrew , then open the pedal upward.

* The pedal can be opened without detaching the thumbscrew completely.

2. Remove the old battery from the battery housing , and remove the battery snap connected to it.

3. Connect the battery snap to the new battery, and place the battery inside the battery housing.

* Be sure to carefully observe the batterys polarity (+ versus -).

4. Slip the coil spring onto the spring base on the back of the pedal, and then close the pedal.

* Carefully avoid getting the battery snap cord caught in the pedal, coil spring, and battery housing.

5. Insert the thumbscrew into the guide bush hole and tighten it securely.
