G-Force mono input effects

Not all effects in the G-Force are full stereo, some just create a stereo effect from a mono input. The Drive and Phaser create mono effects only.

Mixed left+right or left only input

The following table tries to show how inputs of effect blocks behave when routed first in the signal chain (i.e., right after the stereo Gate), compared with being routed after other blocks. Thanks to Ralf for pointing out this distinction.

Effect Input when routed first Input when routed elsewhere
Compressor stereo stereo
Phaser filter left+right left only
Other Filter effects stereo stereo
Panner left+right left+right
Tremolo stereo stereo
Pitch Shift left+right left only
One- and Quad Tap delays left only left only
Stereo, Dual- and Dual Two Tap delays stereo stereo
Drive left+right left only
Chorus/Flanger stereo stereo
Reverb left+right left only

This means that if you pan a Panner, Delay or Pitch Shift signal hard right, the resulting signal becomes muted if a "left only" input effect with 100% Mix is routed after it. The reason for this, according to TC Electronic, is that an Advanced Chorus/Flanger with Phase Reverse On would otherwise be cancelled if its phase reversed stereo output was mixed together by a following effect block. Despite this, the Panner still mixes left+right together.
