Usage precautions

Electrical interference with other equipment In consideration of safety, the G2Nu/G2.1Nu has been designed to provide maximum protection against the emission of electromagnetic radiation from the device and to minimize external electromagnetic interference. However, equipment that is very susceptible to interference or that emits powerful electromagnetic waves should not be placed near the G2Nu/G2.1Nu, as interference could occur. In such a case, place the G2Nu/G2.1Nu and the other equipment sufficiently far apart. With any type of digital control device, the G2Nu/G2.1Nu included, electromagnetic interference could cause malfunction and could corrupt or destroy data. Please use caution. Cleaning Use a soft cloth to clean the panels if they become dirty. If necessary, slightly moisten the cloth. Never use cleansers, wax, or solvents such as paint thinner, benzene or alcohol. Malfunction If the unit should malfunction, disconnect the AC adapter and turn the power OFF immediately. Then, disconnect all other connected cables. Prepare information including the model name, serial number, specific symptoms related to the malfunction, your name, address and telephone number and contact the store where you bought the unit or ZOOM support. Please keep this manual in a convenient place for future reference.

Module
As shown in the illustration above, you can use up to 8 effect units simultaneously. Each of these units is called a "module."
A set of 10 patches is called a "bank." This unit has a total of 20 banks, including user banks AJ, which can be edited and saved and preset banks 09, which can only be recalled. (See the illustration at the top right.)

Effect type

Among the modules, some allow different "effect types" to be activated. For example, when using the MODULATION module (modulation/delay effects) you can choose one of several effect types, including chorus, flanger and delay.
Each operation status of the G2Nu/G2.1Nu is called a "mode." Depending on the currently selected mode, the functions of keys and knobs change. The modes include the play mode in which you choose a patch and play your instrument, the rhythm mode in which you can play back a rhythm pattern, the edit mode in which you can create and change patches, and the store mode in which you can save patches.

Depending on the recording method chosen in step 2, recording occurs as follows. If a note mark was chosen Recording continues for the set time and then loop playback starts (and "PLAY" appears on the display). If "Manual" was chosen When the [] foot switch is pressed again, or the maximum time (about 5 seconds) is reached, loop playback starts (and "PLAY" appears on the display).
