User Manual for The Worm Analog Modulation Pedal

Quick guide from the manual

The Worm is a multi-functional analog modulation pedal that combines four distinct effects: Modulated Wah, Phaser, Tremolo, and Vibrato. This device requires a specific 24V DC power supply and does not support battery operation.

Controls and Operation

The pedal features several controls to shape your sound:

• 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: Controls the speed of the modulation. Turning clockwise increases the speed from slow to fast.
• AUTO / MANUAL/EXP Toggle Switch: Set to AUTO for standard modulation. In MANUAL/EXP mode, the internal modulation is disconnected, allowing the RANGE knob to sweep the effect or enabling the use of an external expression pedal/control voltage.
• STATUS LED and FOOTSWITCH: The LED blinks at the modulation rate when the effect is engaged. The footswitch toggles the effect on and off (True Bypass).

Jacks and Connections

• INPUT Jack: Connect your instrument here (Input impedance: 300 kΩ).
• OUTPUT Jack: Connect to your amplifier or the next effects pedal (Output impedance: 1 kΩ).
• EXP. PEDAL Jack: Connect an expression pedal or a Control Voltage (CV) generator (0–5V only). The expression pedal must use a TRS plug with the tip connected to the wiper.
• 24V PWR Jack: Connect the supplied 24V DC/100mA power adapter.

Power Requirements

Warning: Use only the supplied 24V DC/100mA power adapter. Using an incorrect adapter can cause serious bodily injury, damage the unit, and void the warranty. The Worm does not accept batteries.
