Electro Harmonix Cntl Knob Static Expression Pedal

Take complete command of your expression-controlled effects with the Cntl Knob, a brilliantly simple pedal that puts two preset expression positions right at your feet. This compact and budget-friendly unit replaces the need for a full expression pedal by allowing you to set two distinct values using the EXP 1 and EXP 2 knobs, then toggle between them via the built-in footswitch.

Setting up your preferred positions couldn’t be easier – simply turn each knob to your desired expression level, with fully counter-clockwise representing the heel position and fully clockwise the toe position. Bright LEDs clearly show which preset is currently active, while the pedal can be powered either from your existing pedalboard supply or with EHX’s optional 9.6DC200mA power unit.

The Cntl Knob’s TRS+/- button ensures seamless compatibility across different manufacturers by letting you match the expression polarity to whatever device you’re controlling. A generous 6-foot TRS cable comes included, so you’re ready to connect straight out of the box.
