Model: EHX Next Step Expression Pedal
The EHX Expression Pedal is part of our innovative Next Step Effects series. It does not use a potentiometer, optics or magnetism to sweep expression-enabled controls. The result is a responsive expression pedal that provides precise control over your expression or control- voltage capable effects and instruments.

The EXPRESSION pedal has no moving parts: it does not use a potentiometer, optics or magnetism to sweep expression enabled controls on other devices. The result is a responsive expression pedal that allows precise control over your expression or control-voltage capable effects and instruments.
The EHX EXPRESSION pedal ships from the factory with a TRS cable. The TRS cable is necessary when connecting the EXPRESSION pedal to a device with an expression control input. Plug one end of the included ” TRS cable into the OUTPUT jack of the EXPRESSION pedal; connect the other end of the TRS cable into an effect or instrument with an expression input. Within seconds the EHX logo in the center of the pedal will light. Your EXPRESSION pedal is now ready for use. Please note: as long as a plug is inserted into the OUTPUT jack, a drain is placed on the 9V battery inside the EXPRESSION pedal. We recommend you unplug the OUTPUT jack when the EXPRESSION pedal is not in use to extend battery life.
The RANGE dial located on the right side of the EXPRESSION pedal controls the Heel setting of the pedal’s sweep (or Toe setting with REVERSE engaged). As the numbers on the dial increase, the expression sweep range increases. Minimum range occurs when the control is set to 0; maximum range is achieved at a setting of 10. Please note: When the REVERSE button is out, the RANGE control only restricts the Heel setting, not the Toe. If REVERSE is pushed in, the RANGE control only restricts the Toe setting, not the Heel.
BYPASS SETTING Control
This dial controls the EXPRESSION pedal’s output setting while in bypass mode. A setting of 0 for BYPASS SETTING is equivalent to the Heel position. A setting of 10 on the dial is equivalent to the Toe position. Setting the dial anywhere in between will yield an intermediate bypass setting. Please note: the RANGE and REVERSE controls have no affect on the BYPASS SETTING control. BYPASS SETTING always sweeps through the entire EXPRESSION pedal’s range.
The REVERSE button reverses the direction of the EXPRESSION pedal’s output as it is swept from Heel to Toe. This button has two positions: out and in. Set to out, REVERSE is disengaged and the EXPRESSION pedal’s output increases as you move the pedal from Heel to Toe. In most cases, this is the equivalent of turning a knob in the clockwise direction or pushing a slider control upward. Pushing the REVERSE button to the in position engages the Reverse function. When set to the in position, the output of the EXPRESSION pedal decreases as you move the pedal from Heel to Toe. This is the equivalent of turning a knob counter-clockwise or pushing a slider downward. Please note: the REVERSE button does not change the polarity of the TRS OUTPUT jack, it only changes the direction of the EXPRESSION pedal’s sweep.
OUTPUT Jack: TRS = EXP, TS = CV
The type of cable inserted into the OUTPUT jack determines the output state of the EXPRESSION pedal. When a TRS cable (the cable supplied with the EHX EXPRESSION pedal) is plugged into the OUTPUT jack, the pedal works as a standard expression pedal with the following connections: TIP = potentiometer wiper or output signal, RING = Toe position and SLEEVE = Heel position. This is the standard polarity for the TRS plug of an expression pedal that many in the industry follow including all EHX products as well as BossÂ®/RolandÂ®, MoogÂ®, NordÂ® etc. The REVERSE button does not change the TRS plug polarity, it only changes the direction of the output sweep.
If you plug a standard ” instrument cable, with mono TS plug, into the EXPRESSION pedal’s OUTPUT jack, the EXPRESSION pedal output will automatically change over to Control-Voltage (CV) mode. In CV mode you can use the EXPRESSION pedal as a CV source. The maximum range in CV mode is 0V to 5V. Adjusting the RANGE control will move the minimum voltage from 0V up to approximately 4.5V, the maximum voltage of 5V does not change.
Toggle between bypass and effect mode by tipping the EXPRESSION pedal forward, in the Toe direction, past the flat position of the EXPRESSION pedal. You do not need to tip the EXPRESSION pedal all the way forward; 25% of the total forward travel will do it. The EXPRESSION pedal needs to return to its flat position before you can toggle between bypass and effect mode again. Please note: while in bypass mode, the BYPASS SETTING control on the right side of the EXPRESSION pedal adjusts the output setting.
When the EXPRESSION pedal is in effect mode, the EHX logo in the center of the pedal will light up. In bypass mode, the logo does not light.
Plugging into the OUTPUT jack activates power from the internal 9 Volt battery. The input cable should be removed when the unit is not in use to avoid running down the battery. If an AC Adapter is used, the EXPRESSION pedal will be powered up as long as the AC Adapter is correctly plugged in.
The EXPRESSION pedal’s power jack is located on the same side as the OUTPUT jack. A 9 Volt AC Adapter capable of delivering at least 25mA of current at 9VDC is required to power the EXPRESSION pedal. The inner ring of the 9 Volt AC Adapter must be negative, the outer ring positive. The optional 9V power supply from Electro-Harmonix is 9.6DC-200BI (same as used by BossÂ® & IbanezÂ®) supplies 9.6 Volts DC/200mA. The unit’s battery may be left in or taken out when the AC Adapter is in use. The actual current draw of the EXPRESSION pedal is 12mA.
