DISASSEMBLE THE PEDAL
Remove the four screws that
secure the back of the pedal
housing. Pull the knob off of
the front of the pedal, unscrew
the mounting nuts for the
potentiometer and the switch,
and unscrew the mounting
nuts for the instrument and
power jacks on the side panels.
Gently push the switch and the
pot shaft from the front of the
enclosure and the board should
come right out.
