Electro-Harmonix Control Knob Static Expression Pedal

The Cntl Knob is an affordable, compact, easy-to-use pedal that delivers static remote control for devices with expression control jacks. It lets you set two preset values that represent two positions of a traditional expression pedal and toggle between them with its footswitch.

The pedal’s EXP 1 Knob selects the first expression setting and the EXP 2 Knob the second. On both, fully CCW corresponds to the heel position while fully CW to the toe position. LEDs indicate which knob is active and can be powered by your pedalboard’s power supply or an optional EHX’s 9.6DC200mA PSU.

To maximize the Cntl Knob’s compatibility with other products it’s equipped with a TRS+/- Button that lets you match its expression polarity with the device being controlled. For extra convenience it comes equipped with a 6 foot TRS (Tip-Ring-Sleeve) cable.
