User Manual for Electro-Harmonix The Worm Analog Modulation Pedal

Quick guide from the manual

The Worm is a multi-functional analog modulation pedal featuring four effects: Modulated Wah, Phaser, Tremolo, and Vibrato. The device operates in True Bypass mode when the effect is disengaged. Important: The unit requires the supplied 24V DC / 100mA power adapter. Do not use other adapters, as this may cause damage or injury. The unit does not accept batteries.

Controls

MODE Rotary Switch: Selects between the four available effects: WAH, PHASER, TREMOLO, and VIBRATO.

RANGE Knob: Adjusts the intensity of the effect. Turning from counter-clockwise (minimum) to clockwise (maximum) increases the effect intensity.

RATE Knob: Adjusts the speed of the modulation. Turning from counter-clockwise (minimum) to clockwise (maximum) increases the speed from slow to fast.

AUTO / MANUAL/EXP Toggle Switch: Set to AUTO for standard modulation. Set to MANUAL/EXP to disconnect the internal modulation waveform, allowing the RANGE knob to sweep the effect. In this mode, you can also connect an expression pedal to control the sweep.

STATUS LED and FOOTSWITCH: The LED blinks at the rate of the modulation when the effect is engaged. The footswitch toggles the effect on and off.
