The GT-1000 supports Wet/Dry setups using the DIVIDER block in the effect chain. Setting the DIVIDER to DUAL splits the input signal into two parallel paths. Effect blocks can be moved freely between the wet and dry paths by highlighting a block and pressing and turning knob [6] simultaneously.
Mono Wet/Dry setup
Set the DIVIDER to DUAL to create parallel wet and dry paths. Move effect blocks into the desired path using knob [6]. Use the second page of the DIVIDER settings to adjust the level and ratio for each path.
Stereo Wet/Dry setup
Highlight the speaker icon (ML/R) and turn knob [1] to disable STEREO LINK. This separates the L and R outputs. Move the ML and MR speaker icons to the desired wet or dry paths using knob [6].
Note: When using the DIVIDER, start at a low volume to avoid overload.
