Expression pedal 2 of the G9.2tt is designed for operation with one foot. When the pedal is
fully turned to the right, pushing it strongly down, hitting it, or otherwise exerting strong force
on it will damage the pedal. Be sure to operate the pedal only within its designated range.
If you loosen the pedal too much, the internal screw may come off, and you will no longer be
able to tighten the pedal. Perform this operation with care.
If the screw should have come off inside the unit, contact your dealer or an authorized Zoom
service station.
Never try to open the cabinet of the G9.2tt yourself, and never turn power to the G9.2tt on if
the screw is unsecured inside the unit. Otherwise the electronic circuitry may be seriously
damaged.

Adjusting the Expression Pedal Torque
[Table 2] The table below shows an example for Z-pedal operation when vertical direction is assigned to "PdlPosi V"
and horizontal direction to "PdlPosi H".
Z-Talking
This effect changes the guitar sound into a talking sound. When using the Z-pedal, vowels can be changed in various
ways by moving the pedal in the vertical or the horizontal direction.
Try assigning the vertical direction of the Z-pedal (P2V1 - P2V4) to the "Formant V" parameter and the horizontal
direction (P2H1 - P2H4) to the "Formant H" parameter.

REVERB module
Z-Delay
This is a delay effect which allows adjustment of panning and mix level using the pedal.
Try assigning the vertical direction of the Z-pedal (P2V1 - P2V4) to the "Mix" parameter and the horizontal direction
(P2H1 - P2H4) to the "Pan" parameter.

Z-Dimension
This is a spatial effect which allows adjustment of depth, panning, and reverberation using the pedal.
Try assigning the vertical direction of the Z-pedal (P2V1 - P2V4) to the "Depth" parameter and the horizontal direction
(P2H1 - P2H4) to the "Pan" parameter.

This is a delay effect which causes the effect sound to swirl like a tornado.
Try assigning the vertical direction of the Z-pedal (P2V1 - P2V4) to the "Rate" parameter and the horizontal direction
(P2H1 - P2H4) to the "Width" parameter.
