User Manual for Electro-Harmonix EHX Expression Pedal

Quick Guide

The EHX Expression pedal is designed to control expression parameters on devices equipped with an expression jack. To ensure proper operation, always use the included 1/4 inch TRS cable. Standard 1/4 inch TS instrument cables will not work with this device.

Controls and I/O Jacks

• TRS OUT Jack: Connects the pedal to the expression input of your device using a 1/4 inch TRS cable.
• REV Button: Reverses the sweep direction of the pedal. In the OUT position, the sweep is standard (minimum to maximum). In the IN position, the sweep is reversed (maximum to minimum).
• TRS +/- Button: Adjusts the polarity of the TRS jack for compatibility with various devices. For EHX pedals, this should be set to the OUT position.
• RANGE Knob: Adjusts the minimum setting of the expression pedal. Turning the knob towards 0 moves the minimum sweep setting towards the fixed maximum. Set to 10 for the full range.
