EHX The Worm Analog Modulation Pedal
The Worm Analog Modulation Pedal
Congratulations on your purchase of The Worm, a multi-functional modulation pedal. The Worm is four analog effects in one: Modulated Wah, Phaser, Tremolo and Vibrato.
AC ADAPTOR
Your Worm comes equipped with a 24 volt DC (inner positive) / 100mA external power adapter. Use only the power adapter that is supplied! Using the wrong adapter can cause serious bodily injury and may damage your unit. This will void the warranty.
CONTROLS
MODE Rotary Switch
Selects between the four different types of effects: WAH, PHASER, TREMOLO and
VIBRATO.
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.
RATE Knob
Adjusts the speed of modulation for the effect. As the RATE knob is turned
from the Counter-Clockwise (minimum) position to the Clockwise (maximum)
position, the speed of the effect will go from slow to fast.
AUTO / MANUAL/EXP Toggle Switch
Set this switch to AUTO mode for normal modulation use. When this switch is
set to MANUAL/EXP mode, the internal modulation waveform is disconnected from
the circuit and the RANGE knob will sweep through the effect. In addition,
while in MANUAL/EXP mode, you can connect an expression pedal or control
voltage (between 0 – 5V only) to the EXP. PEDAL jack and use the expression
pedal to sweep the effects.
STATUS LED and FOOTSWITCH
If the effect is engaged, the LED will blink at the same rate that the effect
modulates. If the LED is off, The Worm is in True Bypass mode. The footswitch
engages/disengages the effect.
