The use of an adapter other than the specied type may damage the unit and pose a safety hazard. Connect the AC adapter only to an AC outlet that supplies the rated voltage required by the adapter. When disconnecting the AC adapter from the AC outlet, always grasp the adapter itself and do not pull at the cable. During lightning or when not using the unit for an extended period, disconnect the AC adapter from the AC outlet.

Volume

Caution Do not use the GFX-3 at a loud volume for a long time
since this can cause hearing impairment.
Usage Precautions Electrical interference
For safety considerations, the GFX-3 has been designed to provide maximum protection against the emission of electromagnetic radiation from inside the device, and protection from external interference. However, equipment that is very susceptible to interference or that emits powerful electromagnetic waves should not be placed near the GFX-3, as the possibility of interference cannot be ruled out entirely. With any type of digital control device, the GFX-3 included, electromagnetic interference can cause malfunctioning and can corrupt or destroy data. Care should be taken to minimize the risk of damage.

[Battery operation]

Use four conventional IEC R6 (size AA) batteries (alkaline). The GFX-3 cannot be used for recharging. Pay close attention to the labelling of the battery to make sure you choose the correct type. When not using the unit for an extended period, remove the batteries from the unit. If battery leakage has occurred, wipe the battery compartment and the battery terminals carefully to remove all remnants of battery uid. While using the unit, the battery compartment cover should be closed.

Cleaning

Use a soft, dry cloth to clean the GFX-3. If necessary, slightly moisten the cloth. Do not use abrasive cleanser, wax, or solvents (such as paint thinner or cleaning alcohol), since these may dull the nish or damage the surface.

Changing the Sound of a Patch
The patches of the GFX-3 can be modied by changing effect types and parameters. This section shows how to edit patches.
INPUT COMP/ISO DRIVE EQUALIZER ZNR CABINET MOD REV/DLY OUTPUT

Patch conguration

Each patch of the GFX-3 consists of several effects (effect modules), as shown in the illustration above. A patch is a stored combination of modules, each with their distinct parameter settings. Within each module, there are several different but related effects which are called effect types. For example, the MOD (modulation) module comprises effect types such as CHORUS, PHASER, and WAH, of which one can be selected. The elements that determine the sound of a patch are called effect parameters. Each module has certain effect parameters, whose value can be adjusted with the effect module keys, PARAMETER keys, [VALUE] dial, etc.

Push the expression pedal fully down and release it.
Push strongly, so that pedal touches here.
When foot is lifted, pedal returns slightly.
Hold down the [PEDAL] key while turning power to the GFX-3 on.
The indication "dn" appears on the display.
The adjustment is complete, and group/bank display for the patch appears again.
Fully raise the expression pedal and press the [STORE] key.
The indication "UP" appears on the display.
The position of the pedal in step 3 determines the module on/off switching point. If you want the pedal to perform on/ off switching with a lighter touch, set the pedal in step 3 to a somewhat higher position. If the indication "Er" is shown, repeat the

procedure from step 2.

Effect Types and Parameters
In this section, all effect types and parameters of the modules in the GFX-3 are explained. As shown in the illustration, the GFX-3 has eight effect modules which can be thought of as being connected in series. It is possible to use all effect modules together, or to switch individual modules on and off. Nearly all modules incorporate several effect types, of which one can be selected at a time.

Troubleshooting

No sound, or very low volume
Is the power switch set to ON? Are [INPUT] jack and [PHONES/OUTPUT] jack connected correctly to instrument and amplier? Is the shielded cable defective? Is the GFX-3 set to the mute condition? Is the master level parameter set to a low value? Is the expression pedal pushed down? For some patches, the expression pedal controls the volume. Set it to a suitable position. on the DRIVE module setting.

High noise levels

Adjust ZNR parameter. If problem persists, try reducing GAIN. If BOOSTER or COMP/ ISO module is used, try decreasing GAIN parameter of DRIVE module.
Expression pedal on/off switching does not work properly.
