Effects Specs

• The Zoom G2 and Zoom G7 both provide nine effects modules, which are the underlying effects units that serve as the base structures for more complex effects. With both consoles, these modules are COMP, WAH/EFX1, ZNR, PRE AMP, EQ, CABINET, MOD/EFX2, DELAY, and REVERB. In addition, both the G2 and the G7 are capable of applying a maximum of nine effects simultaneously. Simultaneous effects allow users to combine effects, making for more elaborate, multi-layered sounds. Where the G2 and the G7 differ in terms of effects, however, is in the total number of different types of effects the consoles can produce using their base modules. While the G2 can produce a maximum of 54 different effect types, the G7 can produce a maximum of 92 different effect types.
  
  

Patch Memory

• Patches are the configurations of effects that you can save and recall when using guitar effects consoles. Of the Zoom G2 and Zoom G7, the latter has a larger patch memory, allowing for a larger amount of saved patches. Specifically, the G2 provides 40 preset patches, which Zoom programs on the consoles, and 40 user patches, which you can program to your own liking. This makes for a total of 80 patches. In comparison, the G7 allows for 160 total patches: 80 preset patches and 80 user patches.
  
  

Inputs and Outputs

• For connecting the effects console to peripheral components, including guitars and headphones, the Zoom G7 provides a greater amount -- and broader range -- of inputs and outputs in comparison to the Zoom G2. Specifically, the G2 provides only one 1/4-inch input jack, one line/headphone output jack, an expression pedal input jack and a foot switch input jack. In comparison, the G7 provides a 1/4-inch input jack, an auxiliary 1/8-inch input jack, two line output jacks, one headphone output jack, an expression pedal input jack, a MIDI input/output jack and a USB port. The MIDI and USB connectors allow you to connect the G7 to computers for uploading and downloading audio data.
  
  

Power Requirements

• The Zoom G2 can derive its power from two different sources: a 9-volt AC adapter or four AA alkaline batteries. In comparison, the Zoom G7 can derive its power only from a single power source: a 15 V AC adapter. Being able to run on batteries allows the G2 to operate without the need for a power outlet.
