Do not use the GFX-3 at a loud volume for a long time

Caution

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.

• 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 ﬁnish or damage the surface.

Please keep this manual in a convenient place for future reference.

Changing the Sound of a Patch

The patches of the GFX-3 can be modiﬁed by changing effect types and parameters. This section shows how to edit patches.

INPUT OUTPUT

Select the patch to edit.

Patch conﬁguration

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.

OTE

Also within the same module, different effect types will have different parameters.

Patches for editing can be selected from either a preset group (A, b) or a user group (U/u). Patches from a preset group are read-only. If you have altered such a patch and want to keep it, you must store it in a user group (

To change the patch level, operate the [VALUE] dial.

While the group/bank number indication is shown on the display, the [VALUE] dial can be used to adjust the patch level (ﬁnal output level of the patch).

When you turn the dial, the current patch level setting (1 - 30) appears on the display. A dot (.) in the bottom right of the display indicates that the patch has been edited.

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 ampliﬁer?

• 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.

■

Sound is unnaturally distorted

• Adjust level and GAIN parameters of effect modules.

• Set COMP/ ISO module to OFF.

When a guitar with high output is used with these effects, unwanted distortion may occur depending
