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 GFX-4 can hold a total of 120 patches. These are divided into 60 user patches which are read/write, and 60 read-only preset patches. Both the user patches and preset patches are divided into four groups (A, b, C, d). Each group has 5 banks numbered from 0 - 4, and each bank has 3 patches. To use a patch in the GFX-4, you first call up the bank and then use the three foot switches 1 - 3 to select the patch. User patches GROUP d GROUP C GROUP b GROUP A BANK 4 BANK 3 PATCH 1 BANK 2 PATCH 1 BANKPATCH 2 1 PATCH 1 BANKPATCH 2 0 PATCHPATCH 3 1 PATCH 2 PATCHPATCH 3 1 PATCH 2 PATCH PATCH 2 3 PATCH 3 PATCH 3 Preset patches GROUP d GROUP C GROUP b GROUP A BANK 4 BANK 3 PATCH 1 BANK 2 PATCH 1 BANKPATCH 2 1 PATCH 1 BANKPATCH 2 0 PATCHPATCH 3 1 PATCH 2 PATCHPATCH 3 1 PATCH 2 PATCH PATCH 2 3 PATCH 3 PATCH 3 G RTM (real-time modulation) The RTM function allows use of the expression pedal to adjust DRIVE, MODULATION, or DELAY/REVERB module parameters or the volume in real time. For example, you might use the pedal during a performance to vary the reverb mix balance or adjust wah intensity with your foot. The module, effect type, and parameter, as well as the parameter change direction can be set separately for each patch. G Modes Operation of the GFX-4 is divided into five main modes, as listed below. · Program mode This is the basic operation mode of the GFX-4. The unit is always in this mode after power is turned on. 4 ZOOM GFX-4 Controls and Functions Top Panel ZNR key & LED LEVEL/NAME (level name) key & LED AMP SIM (amp simulator) key & LED STORE key MANUAL/CANCEL key & LED Module keys & LEDs (COMP/OD/ENV, DRIVE, EQUALIZER, PEDAL, MODULATION, PEDAL WAH/PEDAL PITCH , DELAY/REVERB) Expression pedal Controls and Functions GROUP/BANK indicator / / / keys Display BANK foot switch TYPE DOWN/UP key [FX panel 1 - 3] Parameter knobs Foot switches 1 - 3 & LEDs Rear Panel OUTPUT STEREO/PHONES jack OUTPUT MONO jack INPUT jack ACTIVE NORMAL switch MASTER LEVEL knob AC adapter connector POWER switch ZOOM GFX-4 5 Getting Connected Guitar amp/instrument connection Guitar amplifier To use the output of the GFX-4 in mono, connect the OUTPUT MONO jack. To use the output of the GFX-4 in stereo, connect a Y cable to the OUTPUT STEREO jack. * When connecting the GFX-4 to a hi-fi system or a multi- track recorder (MTR), activating the built-in amp simulator ( p. 7) is recommended). Headphone guitar INPUT OUTPUT MONO OUTPUT STEREO/PHONES The ACTIVE NORMAL switch should be set to "NORMAL" when using a conventional passive guitar and to "ACTIVE" when using an active type guitar with high-output pickup or built-in preamplifier. NORMAL NORMAL ACTIVE ACTIVE Getting Connected AC adapter Wind the AC adapter cable around the hook as shown in the illustration to guard against inadvertent disconnection. MTR About the Mono Output The GFX-4 has two output jacks labeled OUTPUT STEREO and OUTPUT MONO. When the OUTPUT MONO jack is used, a mechanical relay switch operates in bypass mode, which results in true bypass (analog bypass where the signal is not subject to any kind of digital processing). I When using effects The OUTPUT MONO jack supplies only the left-channel signal. This is suitable for example for connection to a guitar amp or another effect device. INPUT Digital Processing OUTPUT MONO Volume Pedal Master Level I When using Bypass When the GFX-4 is in bypass mode, the analog input signal appears unchanged at this jack, due to the action of a switching relay. (This means that there is absolutely no sound quality change caused by digital processing.) Note that the expression/volume pedal and the MASTER LEVEL knob have no effect on the signal in this condition. When wishing to use the volume pedal and master level control also in bypass mode, use the OUTPUT STEREO jack. Bypass mode INPUT Digital Processing OUTPUT MONO Volume Pedal Master Level 6 ZOOM GFX-4 Preparations Power Up 1.

ZOOM GFX-4 15 Editing Operations This section describes the various editing operations that can be carried out with the unit. The basic steps for patch editing are as follows. 1. While the GFX-4 is in program mode, select the patch you want to edit. Module is on Module is off Module LEDs The module LEDs show the status of each module within that patch. COMP/OD/ENV, DRIVE, EQUALIZER module LEDs 3. To toggle the selected module between on and off, press the module key of the corresponding FX panel again. Module LED status Lit red Lit green Lit orange Out Module on/off status On Off On Off FX pedal 1 assignment Yes Yes No No You can also switch between on and off by pressing the module key of the module whose LED is flashing. The PEDAL module serves for making expression pedal settings. It is not a regular effect and can therefore not be turned off. COMP/OD/ENV, DRIVE, and EQUALIZER share the FX pedal 1 which can be assigned to any of these modules. However, when the assigned module is off (module LED lit in green), operating the FX pedal 1 only switches module on or off. 4. To switch the effect type of the selected module, use the TYPE DOWN/UP keys on the corresponding FX panel. For example, when switching a module from on to off, the module LED changes from flashing red to flashing green. The assignment of FX panels 1 - 3 to the modules is as follows. · FX panel 1: COMP/OD/ENV, DRIVE, Editing Operations MODULATION, DELAY/REVERB module LEDs Module LED status Lit red Out Module on/off status On Off EQUALIZER module · The MODULATION and PEDAL modules share the FX pedal 2. Normally, the FX pedal 2 controls the MODULATION module, but when the PEDAL module is selected as operation target, the FX pedal 2 controls the PEDAL module. The PEDAL module LED is flashing. · The FX pedal 3 is permanently assigned to the DELAY/REVERB module. It always controls the DELAY/REVERB module. · FX panel 2: PEDAL, MODULATION module · FX panel 3: DELAY/REVERB module The name of the currently selected effect type is shown on the display. Effect type name Lit when type was changed 2. Press one of the module keys (COMP/OD/ENV, DRIVE, EQUALIZER, PEDAL, MODULATION, DELAY/REVERB) to select the target module. The LED of the selected module flashes, and the display shows the name of the effect type selected for that module (if the module is on), or "-OFF--" (if the module is off). Approximate setting of parameters 1 - 3 (Out when there is no parameter) 16 ZOOM GFX-4 · Unlike other modules, the EQUALIZER module has only one effect type. Therefore pressing the TYPE DOWN/UP keys has no effect. (The display shows only EQUALIZER "HIGH".) · When a module that is currently set to off is selected, the effect type and parameter cannot be changed. For the effect types PDLWAH (pedal wah) and PDLPIT (pedal pitch) in the MODULATION module only, it is possible to directly call up the editing display by pressing the PEDAL WAH/PEDAL PITCH key. For details, see page 26. You can also use the / keys and L/M keys to select the effect type and alter the parameter value. The / keys serve to bring up the effect type or parameter 1 - 3, and the L/M keys serve to adjust the value. 6. Use the module keys to select another module and adjust the effect type/parameter value and on/off setting in the same way. 7. When editing is completed, store the patch as required. If you call up another patch in program mode without storing the current patch, any editing changes will be lost. 5. To set the effect parameters of the selected module, operate parameter knobs 1 - 3 of the corresponding FX panel. The display shows the most recently edited parameter name, and the GROUP/BANK indicator shows the value of the parameter. Parameter name Lit when parameter was changed Operation Differences of Manual Mode and Program Mode When the MANUAL key is pressed while the GFX-4 is in program mode, the unit switches to manual mode. (Pressing the key again switches back to program mode.) In manual mode, the foot switches 1 - 3 on the FX panels serve to turn modules on and off. This lets you change the sound of the currently selected patch in a way similar to using a compact effect. Operation differences in manual mode and program mode are listed below. Editing Operations Manual mode Module LED Display GROUP/BANK indicator Module LED of last edited module flashes and display shows parameter name/effect type name. GROUP/BANK indicator shows parameter value.
