Electro Harmonix Worm


Expected in 54 days

Electro Harmonix Worm is modulation madness in a pedal! All-analog multi-effects processor featuring Phaser, Tremolo, Vibrato, and a Neo-modulated Wah. At the heart of The Worm is a specially designed tone-bending engine that creates groundbreaking oscillatory effects.

The Mode Rotary Switch selects between the four different types of effects: Wah, Phaser, Tremolo and Vibrato. The Range Knob adjusts the amount of effect that will be applied to your signal. As the Range knob is turned from the Counter-Clockwise (minimum) position to the Clockwise (maximum) position, the intensity of the effect will increase. The Rate  Knob adjusts the speed of modulation for the effect.

The Toggle Switch set to AUTO means normal modulation use. When this switch is set to Manual mode, the internal modulation waveform is disconnected from the circuit and the Range knob will sweep through the effect. In addition, while in Manual mode, you can connect an expression pedal or control voltage (between 0 – 5V only) to the EXP jack and use the expression pedal to sweep the effects.
