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.

ZOOM GFX-3 |
Introduction
Thank you for selecting the ZOOM GFX-3. This product is a sophisticated Guitar Effects Processor with the following features.
● Versatile array of effects
The Variable Architecture Modeling System (VAMS) developed by ZOOM adapts the internal configuration of the unit to achieve exactly the desired sound. The GFX-3 provides 50 choices, ranging from distortion and modulation effects to spatial sound processing.
● Full complement of distortion effects
20 distortion type effects not only recreate the characteristics of famous vintage amps but also duplicate the sound and operation of renowned compact effects and pedals. The built-in acoustic simulator makes an electric guitar sound like an acoustic instrument.
● 120 ready-to-use patches
Effect module setting combinations can be stored as patches. The GFX-3 offers 60 user patches which can be freely modified, plus 60 preset patches. Together, these 120 settings let you make great music straight away.
● Mode-free editing for creative flexibility
The selectors and keys arranged on the panel let you directly access any effect. Because there is no need for mode switching, editing can be performed quickly even during a performance. The built-in pedal makes things even simpler by letting you vary effect parameters in real time. The GFX-3 is a powerful tool for enhancing any live performance.
● Energizer produces powerful sound
The Energizer lets you match the output of the GFX-3 to the playback system. Enjoy powerful, dynamic sound even with a small guitar amp or an audio system with flat response.
●Designed for use on stage
The metal chassis of the GFX-3 can withstand the rigors of use on stage. Stability is excellent, and the dual power supply allows the unit to be powered either from an AC adapter or from batteries. With one set of alkaline batteries, the unit will operate continuously for up to 11 hours.

Quick Guide
This section explains the basic operation steps, allowing you to use the unit right away.
Selecting a patch
To select a patch, press one of the foot switches [1] - [3] whose LED is not lit.
The single effects (effect modules) in the GFX-3 can be combined, and parameter settings for each effect can be changed to achieve a desired sound. Such a combination of effects with certain parameter settings is called a patch. Patches are always called onto the panel in banks of three, and the foot switches [1] - [3] are used to select the patch.
Group |
Bank number |
To switch to a patch in another group or bank, use the BANK [Q]/[W] keys and then the foot switches [1] - [3].
Patches are organized in user groups (U, u) which can be modified, and preset groups (A, b) which are read-only. Each group comprises ten banks numbered from 0 to 9, and each bank has three patches.
The BANK [Q]/[W] keys select groups and banks in the order U0 - U9, u0 - u9, A0 - A9, b0 - b9.
*Pressing foot switches [1] and [2] together has the same effect as pressing the BANK [W] key, and pressing foot switches [2] and [3] together has the same effect as pressing the BANK [Q] key.
