The meanings of these symbols are as follows: · Handling Caution This symbol indicates explanations about extremely dangerous matters. If users ignore Warning this symbol and handle the device the wrong way, serious injury or death could result. This symbol indicates explanations about dangerous matters. If users ignore this symbol and handle the device the wrong way, bodily injury and damage to the equipment could result. Since the GFX-4 is a precision electronic device, avoid applying excessive force to the switches and buttons. Also take care not to drop the unit, and do not subject it to shock or excessive pressure. · Alterations Caution Never open the case of the GFX-4 or attempt to modify the product in any way since this can result in damage to the unit. Caution · Connecting cables and input and output jacks Caution Please observe the following safety tips and precautions to ensure hazard-free use of the GFX-4. You should always turn off the power to the GFX-4 and all other equipment before connecting or disconnecting any cables. Also make sure to disconnect all cables and the AC adapter before moving the GFX-4. · Power requirements Warning · The GFX-4 is powered by the supplied AC adapter . · To prevent malfunction and safety hazards, Do not use any other kind of AC adapter. · When using the GFX-4 in an area with a different line voltage, please consult your local ZOOM distributor about acquiring a proper AC adapter. · Environment Avoid using your GFX-4 in environments where it will be exposed to: Caution · Extreme temperature · High humidity or moisture · Excessive dust or sand · Excessive vibration or shock Usage Precautions · Electrical interference For safety considerations, the GFX-4 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-4, as the possibility of interference cannot be ruled out entirely. With any type of digital control device, the GFX-4 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-4. 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. 2 ZOOM GFX-4 Introduction Thank you for selecting the ZOOM GFX-4 (simply called the "GFX-4" in this manual). The GFX-4 is a sophisticated Guitar Effects Processor with the following features. G Versatile array of effects The Variable Architecture Modeling System (VAMS) adapts the internal configuration of the unit to achieve exactly the desired sound. The GFX-4 includes vintage effects such as famous overdrive, distortion, compressor, and phaser sounds of the seventies and eighties, as well as ultramodern processing functions. Up to eight effects can be freely combined for simultaneous use. Introduction G Great choice of distortion sounds In addition to traditional guitar amplifier characteristics, the GFX-4 uses modeling technology to duplicate the sound and operation feel of celebrated compact distortion effects. Well-proven combinations such as booster + distortion or compressor + overdrive can be established quickly and easily. By combining distortion effects with the built-in amp and cabinet simulator, you can get optimum sound also for line out recording. G Designed to get the best out of any guitar The ACTIVE NORMAL switch provides quick and precise impedance and level matching for any guitar. Whether you have a passive pickup or use an active pickup or integrated preamp, your instrument will sound its best. The OUTPUT MONO jack uses analog bypass with a mechanical switch, so that the output in bypass mode is not subject to any kind of digital signal processing. G Simple and intuitive operation Thanks to three FX panels, the GFX-4 can be operated like a series of compact effects. Foot switches are convenient for turning effects on and off, and sound parameters can be adjusted quickly with rotary controls. The Easy Edit function is a snap to use also during a performance. With the GFX-4, playing your instrument and editing the sound is one seamless operation. G Extensive patch library A combination of effects can be assigned a name of up to six characters and stored as a patch in the memory of the unit. There are 60 user patches (4 groups x 5 banks x 3 patches) which can be freely rewritten, plus 60 preset patches that make the unit ready to use right out of the box. The possibilities are almost endless. G Great for use on stage The GFX-4 incorporates an expression pedal that can serve as real-time effect controller or volume pedal. The easy-to-read 6-character display and 2-character indicator make it easy to check patch names and settings at a glance, which is helpful during a live gig. In order to get the most out of this sophisticated product, please read this manual carefully before use. We recommend that you keep the manual at hand for future reference. ZOOM GFX-4 3 Terms Used in This Manual This section explains some important terms that are used throughout the GFX-4 documentation. G Module A "module" is a section that works like a stand-alone compact effect device for tailoring certain aspects of the sound. In the GFX-4, you can use the six modules Patch COMP/OD/ENV, DRIVE, EQUALIZER, PEDAL, MODULATION, and DELAY/REVERB as well as the ZNR (Zoom Noise Reduction) + AMP SIM (Amp Simulator) simultaneously. Terms Used in This Manual INPUT COMP/OD/ENV Module DRIVE EQUALIZER PEDAL MODULATION DELAY/REVERB OUTPUT G Effect types and parameters Within each effect module, there are various effect types which are specific processing functions. The various settings of the currently selected effect type are called parameters. By selecting an effect type and varying the parameters, you can create a new effect. The mode is used for switching patches and for editing the currently selected patch. · Manual mode This mode lets you switch modules on and off, operating the unit in the same way as a compact effect with the knobs and foot switches on the FX panels. · Store mode This mode serves for storing patches edited in program mode or manual mode in the memory of the unit. It also allows changing the store positions of user patches. · Bypass/mute mode When the GFX-4 is in the bypass condition, effect processing is temporarily turned off and only the original sound is heard. In the mute mode, all sound is turned off and the built-in chromatic tuner can be used. · Special mode This mode serves for making amp simulator and ZNR settings, patch name and patch level settings, and for returning the GFX-4 to the factory default condition. G Patch/group/bank Effect module combinations and effect parameter settings are stored in memory as "patches". The ...
