Features

Thank you for selecting the ZOOM G2.1u (hereafter simply called the "G2.1u"). The G2.1u is a multi effect processor with the following features and functions.

Latest processing technology for outstanding performance

96 kHz / 24 bit sampling (with 32 bit internal processing) assures excellent sound quality. Frequency response remains flat up to 40 kHz, and input-converted signal-to-noise ratio is an amazing 120 dB, demonstrating the high level of performance achieved by the G2.1u. The G2.1u also has a USB connection and can be used as a direct guitar/computer interface.

Versatile palette of effects including new creations

Out of a total of 54 effects, up to nine (including ZNR) can be used simultaneously. The high-quality choices provided by the G2.1u include distortion effects that simulate the tones of famous amps and effects pedals, 6-band guitar EQ and delay effects with "hold" controloperated by foot switch.

Great for live performances and direct recording

The distortion effect module provides two different algorithms for each of its 17 effect types, one for live performance and one for direct recording. Depending on the on/off setting of the CABINET & MIC effect which simulates amp cabinet sound and mic characteristics, the most suitable algorithm is automatically selected, giving you the best sound for any application.

Integrated rhythm functions and auto-chromatic tuner

A number of rhythm patterns using realistic PCM drum sounds are provided. This is convenient for use as a metronome during individual practice or to provide a simple rhythm part for a quick session. An auto-chromatic tuner for guitar is also built right into the unit, allowing you to easily tune your instrument also at home or on stage.

Sophisticated user interface

The combination of a rotary type selector and three parameter knobs make the effect editing process intuitive and quick. The mute interval when switching patches has been reduced to less than 5 milliseconds. Seamless patch changing is now a reality.

Dual power supply principle allows use anywhere

The G2.1u can be powered from four IEC R6 (size AA) batteries or an AC adapter. Continuous operating time on batteries is approximately 7.5 hours with alkaline batteries.

Easy operation with expression pedal and foot switch

The expression pedal on the top panel lets you adjust the tonal quality of an effect or the volume in real time. An optional expression pedal (FP01/FP02) or foot switch (FS01) can be connected to the CONTROL IN jack. The external expression pedal is used for controlling the volume. The foot switch is convenient for quickly toggling effect programs or for setting the tempo of the rhythm function.

Please take the time to read this manual carefully so as to get the most out of the unit and to ensure optimum performance and reliability.

Terms Used in This Manual

This section explains some important terms that are used throughout the G2.1u documentation.

IN OUT

Effect module

As shown in the illustration above, the G2.1u can be thought of as a combination of several single effects. Each such effect is referred to as an effect module. In addition to modules comprising compressor effects (COMP), amp simulator/distortion effects (DRIVE), and modulation/special effects (MOD/SFX), the G2.1u also provides a module for ZNR (ZOOM Noise Reduction). Parameters such as effect intensity can be adjusted for each module individually, and modules can be switched on and off as desired.

Effect type

Within some effect modules, there are several different effects which are referred to as effect types. For example, the modulation/SFX effect module (MOD/SFX) comprises chorus, flanger, pitch shifter, delay, and other effect types. Only one of these can be selected at a time.

Effect parameter

All effect modules have various parameters that can be adjusted. These are called effect parameters. In the G2.1u, effect parameters are adjusted with the parameter knobs 1 – 3. Similar to the knobs on a compact effect, these change aspects such as tonal character and effect intensity. Which parameter is assigned to each knob depends on the currently selected effect module and effect type.

Operating the G2.1u on batteries

Patch

In the G2.1u, effect module combinations are stored and called up in units referred to as patches. A patch comprises information about the on/off status of each effect module, about the effect type used in each module, and about effect parameter settings. The internal memory of the G2.1u holds up to 80 patches (including 40 patches which allow read/write).

Bank and area

A group of ten patches is called a bank. The memory of the G2.1u comprises a total of eight banks, labelled A to d and 0 to 3. Banks A – d form the user area which allows read/write. Banks 0 to 3 are the preset area containing read-only patches. The patches within each bank are numbered 0 through 9. To specify a patch of the G2.1u, you use the format "A1" (patch number 1 from bank A), "06" (patch number 6 from bank 0), etc.

Play mode/edit mode

The internal status of the G2.1u is referred to as the operation mode. The two major modes are "play mode" in which you can select patches and use them for playing your instrument, and "edit mode" in which you can modify the effects. The module selector serves for switching between the play mode and edit mode.

Insert four fresh IEC

R6 (size AA) batteries.

• If the DRIVE module is set to OFF for the currently selected module (display shows "oF"), Parameter knobs 1 and 2 have no effect.

• Changes made here are temporary and will be lost when you select another patch. To retain the changes, store the patch in the user area.

• The master level in common to all patches is set in edit mode (→ p. 34).

Adjusts the PATCH LEVEL parameter (output level of the entire patch).

Select a patch

To switch the patch, press one of the [W]/[Q] foot switches.

Pressing the [W] foot switch calls up the next lower patch, and pressing the [Q] foot switch calls up the next higher patch.

Repeatedly pressing one foot switch cycles through patches in the order A0 – A9 ... d0 – d9 → 00 – 09 ... 30 – 39 → A0, or the reverse order.

ZOOM G2.1u

Directly selecting a bank

To select the banks A – d, 0 – 3 directly, use the BANK [-]/[+] keys.

Pressing the BANK [-] key calls up the next lower bank, and pressing the BANK [+] key calls up the next higher bank.

Using the Tuner

The G2.1u incorporates an auto-chromatic tuner. To use the tuner function, the built-in effects must be bypassed (temporarily turned off) or muted (original sound and effect sound turned off).

Switch to bypass or mute

Setting the G2.1u to the bypass

In play mode, press both [W]/[Q] foot switches together briefly and release.

Setting the G2.1u to the mute state

In play mode, press both [W]/[Q] foot switches together and hold for at least 1 second.

Patch change at bypass/mute

When you press both [W]/[Q] foot switches together while playing your instrument, the bypass/mute condition is activated. However, the sound may change momentarily just before the condition is activated. This is because the G2.1u switches to the next higher or lower patch when one of the foot switches is pressed slightly earlier. (When you cancel the bypass/mute condition, the original patch number will be active again.) This kind of behavior is not a defect. It is due to the very high speed at which the G2.1u responds to patch switching. To prevent the sound change caused by the above condition, do not produce sound with your instrument until the bypass/mute condition is fully established.
